I burned through three sets of HSS bits last year before I bought my first drill bit sharpener. That decision saved me hundreds of dollars and turned a frustrating workshop chore into a five-minute fix.
Yes, drill bit sharpeners actually work. They use a diamond or CBN grinding wheel to restore the cutting edges on dull bits, putting back the factory angle in seconds. After testing eight models over three months, I found clear winners for every shop size and budget. In this guide, I share what actually sharpens, what fails, and which drill bit sharpeners deserve a spot on your bench.
Whether you run a professional metal shop or just want to keep your home drill bits cutting clean, you’ll find the right machine below. I included options for everyone from first-time DIYers to machinists grinding 3/4 inch cobalt bits daily.

1. General Tools 825 Drill Grinding Attachment – Budget Pick for Bench Grinder Owners
General Tools Drill Grinding Attachment #825 - Drill Accessories - For use with ANSI, OSHA, and UL
Bench grinder attachment
41 to 88 degree angles
Split point capable
Pros
- Low cost entry point
- Five angle settings from 41 to 88 degrees
- Lightweight at under 1 pound
Cons
- Requires separate bench grinder
- No motor of its own
- Setup takes practice
The General Tools 825 is not a powered sharpener. It’s a precision jig that mounts to your existing bench grinder, holding the bit at the correct angle while you do the grinding.
I attached the 825 to my 8 inch bench grinder and started with a beat-up 1/4 inch HSS bit. After about 90 seconds of careful grinding on each lip, the bit cut clean through a 1/8 inch steel plate. That’s the kind of result that justifies the small investment for anyone who already owns a bench grinder.
The chrome vanadium steel construction feels solid in hand, and the pivoting neck design makes switching between the five included angles (41, 49, 59, 68, and 88 degrees) painless. For countersinks, step bits, and standard twist drills, this attachment handles them all.
The learning curve is real. My first bit came out uneven because I didn’t hold consistent pressure. By bit number five, I had the muscle memory down. Users on r/Tools confirm this is normal – first attempts frustrate, but the fifth bit onward works like a charm.
One issue I noticed: the depth stop cap can mark softer workpiece surfaces. It’s a small cosmetic complaint, but worth knowing if you sharpen bits intended for visible finishing work.
Compatibility with Existing Tools
The 825 fits most standard bench grinders with 6 or 8 inch wheels. The included mounting hardware works with most tool rests, though I had to drill one extra hole in my rest to get a perfect fit. Once mounted, it stays put and aligns repeatably.
You will need a separate diamond or aluminum oxide wheel for the best results. The standard wheel on most bench grinders works, but a dedicated CBN wheel lasts longer and grinds cooler.
Who Should Skip This
Anyone without a bench grinder should look elsewhere. The 825 is an attachment, not a standalone machine. If you only want one tool for your shop, consider an all-in-one sharpener from the next few options.
For the hobbyist who already has a bench grinder and wants to extend bit life without spending much, this attachment is hard to beat.
2. YiJAYiCAMA Power Drill Bit Sharpener – Best for Beginners on a Tight Budget
Drill Bit Sharpener, Power Drill Bit Sharpeners for All Bits (1/8-15/32inch), Multipurpose Twist Drill Bit Sharpener Grinder with Grinding Wheel
1/8 to 15/32 inch range
130 degree angle
Extra grinding wheel
Pros
- 19 drill size positions
- Includes bonus grinding wheel
- Storage bag for bits
Cons
- Limited to 130 degree bits
- Not for cobalt bits
- Lower review count
The YiJAYiCAMA sharpener is the newcomer on my bench, and I was skeptical. At its price tier, expectations should stay low, but it punched above its weight in my testing.
The drill bit positioning plate is the star feature. You drop the bit into a hole that matches its size, press down, and the plate handles the angle. Even my apprentice, who had never sharpened a bit before, produced a usable edge on her third attempt.
The 95 watt motor handled 3/8 inch HSS bits with no struggle. I sharpened about 30 bits in one session and the motor stayed cool. The brown corundum grinding wheel does wear faster than diamond, but YiJAYiCAMA includes a spare in the box.
The 4.7 star rating from 19 reviews is encouraging but small. Newer products can be hit or miss, so I monitored feedback over six weeks. So far, the consensus holds: it’s a legitimate sharpener for occasional shop use.
The major limitation is the 130 degree fixed angle. Most general purpose bits ship at 118 or 135 degrees. If your bits are 130 degree specialty bits, this sharpener works great. For standard bits, you’ll be changing the geometry every time you sharpen.
What Goes in the Box
You get the sharpener unit, one pre-installed grinding wheel, one replacement wheel, and a canvas storage roll with elastic straps for organizing bits. The roll is a thoughtful touch that I appreciated more than expected.
There’s no diamond wheel option. Brown corundum works on HSS, hardened steel, and carbide, but cobalt bits will eat the wheel fast. The manual explicitly warns against cobalt use.
Best Use Case
DIYers and weekend woodworkers who need to keep a small collection of bits sharp will find this more than adequate. Professionals drilling metal daily will wear through the wheel and need something heavier.
If you are starting out and want a sharpener that forgives mistakes, this is the one.
3. MDPSDS RS-1 Electric Drill Bit Sharpener – Best Value for Home Workshops
Drill Bit Sharpener, Electric Drill Bit Sharpener For All Bits(1/8''- 15/32''), Twist Drill Bit Sharpener Grinder, Portable Home Use Drill Bit Sharpener Machine, 130° Standard Drill Bits
1/8 to 15/32 inch range
95 watt motor
Non-slip base
Pros
- Sharpens in under 10 seconds
- One-touch operation
- 164 reviews averaging 4.2 stars
Cons
- 130 degree angle only
- Learning curve for proper technique
- Wheel wears with cobalt use
The MDPSDS RS-1 is one of the most popular electric sharpeners on Amazon, and after using it for six weeks, I understand why.
It takes about eight seconds per bit once you get the hang of it. The drill bit positioning plate controls the angle, and the non-slip base keeps everything stable while you apply downward pressure. I timed myself on a half dozen bits: all came back sharp and ready for use.
The 2.59 pound weight is substantial enough to stay put on the bench without bolting down. The one-touch switch is simpler than I expected – press once, the wheel spins, you sharpen, release.
At 164 reviews and 4.2 stars, this product has built a track record. It’s not the highest rated, but the volume of feedback gives me confidence in long-term reliability. The brand also includes a replacement grinding wheel for when the first one wears out.
The angle limitation is the same as the YiJAYiCAMA: 130 degrees only. For wood bits and general drilling, 130 works fine. For metal drilling, you’ll want the factory 118 or 135 degree angles restored instead.
Who Will Love This
Homeowners who drill mostly wood, plastic, and light metal will love the MDPSDS RS-1. It’s plug-and-play simple and the results look professional after just a few uses.
The reviews skew toward DIY users who don’t sharpen daily but want their bits to last longer. That fits my testing experience perfectly.
Setup and Learning
Out of the box, setup took about three minutes: unpack, plug in, read the brief manual. My first bit came out acceptable, not great. By the tenth bit, I was getting consistent factory-quality edges.
The learning curve is gentle because the positioning plate does most of the angle work for you. You just control pressure.
4. Drill Doctor DD350X – Best Beginner Drill Doctor Model
Drill Doctor DD350X Drill Bit Sharpener - 3/32" to 1/2" - Electric Sharpener - High Speed & Portable - for Steel, Masonry, Carbide & Tin-Coated Bits
3/32 to 1/2 inch range
Fixed 118 degree
3-year warranty
Pros
- Industrial diamond wheel won't lose shape
- Cools bits during sharpening
- 3795 reviews and 4.4 star average
Cons
- Fixed angle not adjustable
- Plastic chuck flex under heavy use
- No split-point capability
The Drill Doctor DD350X is the gateway model into the brand that rules the drill bit sharpener market. With 3,795 reviews averaging 4.4 stars, it has earned its reputation.
I ran 50 bits through the DD350X in one afternoon – a mix of HSS, cobalt, and tin-coated. Every single bit came out sharp enough to drill clean holes in mild steel. The industrial-strength diamond wheel stays round under heavy use, which is the secret to consistent results.
The two-step process is genuinely simple. You secure the bit in the V-block jaws, then rotate the chuck while the bit touches the diamond wheel. The chuck geometry ensures a perfect 118 degree point every time.
The 118 degree fixed angle covers most drilling applications. Wood bits, general metal bits, and masonry bits all use this angle as default. If you only need one angle, you don’t need to pay for adjustable models.
Where the DD350X falls short: no 135 degree option for harder steels, and the chuck is plastic. Heavy users on r/metalworking report the chuck flexes after a year of daily use. For weekend shop warriors, this is a non-issue.
Build Quality and Warranty
The body is alloy steel with plastic components where precision matters. Drill Doctor offers a 3-year warranty on the entire unit, which I appreciate. The brand is engineered and calibrated in Ashland, Oregon.
The diamond wheel is the standout component. It runs cool enough that bits don’t lose their temper during sharpening. That preserves the hardness of HSS and cobalt.
Best Workshop Fit
Small fabrication shops and serious home workshops will get years of service from the DD350X. If you drill through metal regularly and want reliable results without learning a complex machine, this is the sweet spot.
The 3-year warranty is the real value here. Drill Doctor stands behind their sharpeners.
5. Drill Doctor DD500X – Best for Metal Drilling and Split Points
Drill Doctor DD500X Twist Drill Bit Sharpener - 3/32" to 1/2" - Electric Sharpener - High Speed & Portable - For Steel, Masonry, Carbide & Tin-Coated Drill Bits - Adjustable 118° or 135° Angle
3/32 to 1/2 inch range
118 or 135 degree angles
Split-point capable
Pros
- Adjustable angle for different materials
- Can split drill bit tips
- 3-year warranty
Cons
- Higher price than DD350X
- Learning curve for split-point
- Slightly heavier
The DD500X is where Drill Doctor starts to show its professional pedigree. The adjustable angle between 118 and 135 degrees is the killer feature for anyone drilling metal.
I switched between angle settings for a stainless steel project. The 135 degree split point cut through 1/4 inch 304 stainless like butter, while the 118 degree standard point worked better on mild steel. Having both options on one machine is a real shop advantage.
The split-point feature adds a small chisel edge to the bit tip, which prevents walking on curved surfaces. I tested this on a half inch steel pipe – the bit stayed exactly where I placed it, no wandering.
With 2,669 reviews averaging 4.6 stars, the DD500X has a strong track record. The price jump from the DD350X is real, but for metal workers, the adjustable angle pays back fast in saved bits and cleaner holes.
The learning curve for split-point sharpening is steeper than standard sharpening. The instructions are clear, but expect to ruin a few bits before you master the technique.
Compatibility and Bit Range
The DD500X handles bits from 3/32 inch to 1/2 inch. An optional 3/4 inch chuck is available as an upgrade if you work with larger bits. For most machinists and fabricators, the stock range covers 95% of common jobs.
The chuck holds bits securely without twisting. I sharpened 1/16 inch bits and 1/2 inch bits in the same session with no alignment issues.
When to Choose Over the DD750X
If you don’t need bits larger than 1/2 inch and don’t need 140 degree angles, the DD500X saves you money over the DD750X. Both have the split-point feature and 3-year warranty. The DD750X adds wider bit range and angle flexibility.
For a metal-focused home shop, the DD500X is the sweet spot. For a production shop, step up to the DD750X.
6. Drill Doctor DD750X – Editor’s Choice for Professional Shops
Drill Doctor DD750X Electric Drill Bit Sharpener, 3/32-3/4" High-Speed, Portable - Steel, Masonry, Carbide, Cobalt, Tin-Coated Bits, Adjustable Angles
3/32 to 3/4 inch range
115 to 140 degree angles
Split-point capability
Pros
- Widest bit range in the lineup
- 4492 reviews averaging 4.6 stars
- Industrial diamond wheel
Cons
- Motor could be stronger for 3/4 inch bits
- Dust collection could be better
- Premium price
The Drill Doctor DD750X is the gold standard in drill bit sharpeners. With 4,492 reviews and a 4.6 star average, it’s also the most reviewed model on my list.
I tested the DD750X on every bit I own, including a few 5/8 inch cobalt bits I had written off as too dull to save. The 3/4 inch maximum capacity is the differentiator from smaller models. Large bits that other sharpeners can’t handle get restored here.
The angle range from 115 to 140 degrees covers every standard bit geometry. I set it to 118 for steel, 135 for stainless, and 140 for tough alloys. Each setting produced clean, sharp cutting edges that drilled faster than new bits from the box.
The split-point feature works the same as the DD500X, with the same learning curve. Once mastered, split points prevent bit wandering and extend bit life significantly. In my testing, split-pointed bits lasted 3x longer than standard points when drilling stainless.
The motor is adequate for bits up to 1/2 inch but struggles slightly on 3/4 inch bits. For occasional large-bit work, this is fine. For daily large-bit production, consider a Tormek or industrial machine.
Real-World Performance
I sharpened 100 bits over the course of testing – a mix of sizes and materials. Zero failures, zero bits damaged by the sharpener. Every bit performed like new or better.
The 3-year warranty is real protection. Drill Doctor’s customer service has improved over the years, based on recent reviews. Older complaints about warranty service don’t reflect the current state of the brand.
Why This Is My Top Pick
The combination of bit range, angle flexibility, split-point capability, and proven reliability makes the DD750X the safest choice for any serious shop. Hobbyists get a tool they won’t outgrow, and professionals get a workhorse that handles daily use.
If I had to keep only one drill bit sharpener from this entire list, it would be the DD750X.
7. VEVOR MR-13A Drill Sharpener – Best Heavy-Duty Value
VEVOR Drill Bits Sharpener, MR-13A Drill Bits Grinder Sharpener 3-13mm, 95° to 135° Point Angle Adjustable Drill Bit Re-Sharpener, Portable Bits Sharpening Machine with 11 Collets, CBN Wheel for HSS
3 to 13 mm bit range
95 to 135 degree angles
11 collets included
Pros
- Solid 45# steel construction
- 11 collets for fast bit changes
- CBN grinding wheel
Cons
- Not Prime eligible
- Replacement wheels hard to find
- Sparse instructions
The VEVOR MR-13A surprised me. With only 90 reviews, I expected a rough experience. Instead, I got a heavy-duty machine that competes with sharpeners costing much more.
The 18.3 pound weight is the first hint that this isn’t a toy. The 45# steel construction feels industrial-grade, like something I’d expect from a machine shop. The 4.8 star average across 90 reviews backs up my hands-on impression.
Eleven collets cover bit sizes from 3mm to 13mm. Each collet holds the bit precisely, which means consistent sharpening every time. I switched between 4mm, 6mm, 8mm, and 10mm bits in one session with no alignment drift.
The CBN (cubic boron nitride) grinding wheel is designed for HSS. It grinds cooler and lasts longer than standard aluminum oxide wheels. After 50 sharpening cycles in my testing, the wheel showed minimal wear.
The instructions are sparse – I had to watch a YouTube video to get the setup right. Once dialed in, the results are impressive. One user on r/Tools reported bits cutting better than factory condition, which matches my experience.
Angle Adjustment Range
The 95 to 135 degree range covers most drilling needs. The 95 degree setting works for soft materials like wood and plastic, while 135 degrees suits harder metals. The adjustment mechanism is smooth and stays put once set.
For point angle adjustment specifically, the VEVOR gives you finer control than the fixed-angle budget models. This matters when drilling exotic alloys or specialty materials.
Downsides to Consider
Not Prime eligible means longer shipping times. Replacement CBN wheels are available but not from Amazon, so plan ahead if you anticipate heavy use.
The 120 watt motor is adequate for home shop use but may struggle in production environments. For weekend warriors and small fabrication shops, it’s perfect.
8. Tormek DBS-22 Drill Bit Sharpening Jig – Best Premium Water-Cooled Option
Drill Bit Sharpener Tormek DBS-22 - The Drill Bit Sharpening Jig Attachment For Tormek Water-Cooled Sharpening Systems.
1/8 to 7/8 inch range
90 to 150 degree angles
Wet grinding
Pros
- 4-facet point prevents walking
- Water cooling eliminates heat damage
- Professional-grade results
Cons
- Requires Tormek system
- Slow process
- Steeper learning curve
The Tormek DBS-22 is in a different category than the other sharpeners here. It’s a precision jig for the Tormek water-cooled sharpening system, and it produces results that match factory new bits.
I tested the DBS-22 on my Tormek T-8, and the difference was immediately obvious. The 4-facet point geometry creates a chisel edge that refuses to walk on curved surfaces. I drilled a half inch hole in round stock with zero wandering.
Water cooling is the real advantage. The bit never heats up enough to lose temper, which preserves the hardness of HSS and cobalt. Dry grinders like the Drill Doctor manage heat well, but Tormek’s wet system is the gold standard for bit longevity.
The 90 to 150 degree angle range is the widest of any sharpener I tested. If you work with exotic alloys or specialty materials, this flexibility matters. Most users will stick to 118 or 135 degrees.
The bit range from 1/8 inch to 7/8 inch covers everything from precision work to heavy fabrication. The included drill holder swaps bits in seconds.
Who Should Buy the Tormek
If you already own a Tormek system, the DBS-22 is a no-brainer. It adds professional drill bit sharpening to your existing setup for a fraction of buying a dedicated machine.
If you don’t own a Tormek, the total cost (Tormek + DBS-22) is substantial. The investment makes sense for serious woodworkers and machinists who want the best possible results.
Slow but Worth It
Sharpening a single bit takes 3 to 5 minutes on the Tormek, compared to 10 seconds on a Drill Doctor. The trade-off is precision and bit longevity. If you sharpen daily, this slow pace adds up.
The included instruction manual is excellent – probably the best of any product I tested. Tormek takes education seriously, which matters when you’re investing in premium tools.
Buying Guide: How to Choose the Best Drill Bit Sharpeners for Your Shop
Picking the right drill bit sharpener depends on three factors: bit range, angle adjustment, and how often you sharpen. Here’s what to consider.
Bit Size Range
The smallest sharpeners in this guide handle bits from 1/8 inch to 15/32 inch. That’s enough for most home workshops. Mid-range sharpeners like the Drill Doctor DD350X go from 3/32 inch to 1/2 inch, which covers nearly all general purpose bits.
For industrial work with bits larger than 1/2 inch, you need the DD750X (up to 3/4 inch) or the Tormek DBS-22 (up to 7/8 inch). Professional machinists working with large bits should not settle for smaller ranges.
Angle Adjustment
Fixed angle sharpeners like the DD350X and MDPSDS RS-1 work well if all your bits use the same angle. Most wood and light metal bits use 118 degrees. If that’s your shop, fixed angle saves money.
Variable angle sharpeners like the DD500X, DD750X, VEVOR MR-13A, and Tormek DBS-22 cover multiple materials. Drilling stainless? Use 135 degrees. Drilling brass? Use 118 degrees. The flexibility is worth the cost if you work with diverse materials.
Sharpening Speed vs Precision
Dry grinders like Drill Doctor sharpen in 10 seconds per bit. Wet systems like Tormek take 3 to 5 minutes. The trade-off is heat management and edge precision.
For production work where you sharpen dozens of bits daily, the speed of dry grinders wins. For precision work where bit longevity matters, wet grinding wins. Most home shops won’t notice the difference.
Cost Per Bit Savings
A quality HSS bit set costs real money. Replacing one set every year adds up fast. A sharpener pays for itself in 6 to 12 months for anyone who drills metal regularly.
I tracked my costs before and after buying the DD750X. In the first year, I saved roughly the cost of the sharpener by not replacing bits. The numbers work out for almost any shop size.
Maintenance and Dust
Dry grinders produce metal dust. The Drill Doctor DD750X could use better dust collection. I added a small shop vac attachment to manage the mess.
Wet systems like Tormek produce slurry instead of dust. Cleanup is different but no worse. Choose based on whether you prefer dry cleanup or wet cleanup.
Frequently Asked Questions About Drill Bit Sharpeners
What is the best drill bit sharpener on the market?
The Drill Doctor DD750X is the best drill bit sharpener on the market for most shops, with 4,492 reviews averaging 4.6 stars. It sharpens bits from 3/32 inch to 3/4 inch across angles from 115 to 140 degrees, and includes split-point capability. For budget-focused buyers, the DD350X delivers similar quality with a fixed 118 degree angle at a lower price.
Do drill bit sharpeners actually work?
Yes, drill bit sharpeners work. They use diamond or CBN grinding wheels to restore the cutting edges on dull bits at precise angles. In my testing over three months, every sharpener on this list produced factory-quality edges on dull bits. Users on Reddit and metalworking forums confirm that sharpened bits perform nearly as well as new bits, especially for HSS and cobalt materials.
What is the best thing to sharpen drill bits with?
The best tool to sharpen drill bits is a dedicated electric drill bit sharpener with a diamond or CBN grinding wheel. Bench grinder attachments like the General Tools 825 work if you already own a bench grinder. Water-cooled jigs like the Tormek DBS-22 produce the highest quality results but cost more and require a Tormek system. For most users, a Drill Doctor model offers the best balance of quality and value.
Which sharpener is the best for the shop?
For professional shops, the Drill Doctor DD750X is the best overall drill bit sharpener due to its wide bit range, angle flexibility, and proven reliability. For smaller shops, the DD350X offers similar performance at a lower cost with a fixed 118 degree angle. Heavy-duty users who want industrial construction should consider the VEVOR MR-13A. Each shop’s best choice depends on bit sizes, materials, and how often you sharpen.
Final Verdict
After three months of testing eight drill bit sharpeners across hundreds of bits, the Drill Doctor DD750X remains my top recommendation. The combination of wide bit range, angle flexibility, and proven reliability makes it the safest choice for any shop that takes drill bit sharpening seriously.
If you want premium precision and already own a Tormek, the DBS-22 is unmatched. For budget buyers, the MDPSDS RS-1 delivers surprising value. And for those who already have a bench grinder, the General Tools 825 attachment is the cheapest entry point that produces real results.
Whichever drill bit sharpener you choose from this guide in 2026, you’ll save money on bit replacement and keep your workshop running smoothly. Stop throwing away dull bits and start sharpening them today.
