The 5 Best Drill Bit Sharpeners of 2026

By Gayle Woods Editors Updated 5 products scored

The sound that finally pushed me to buy a drill bit sharpener was a 3/16-inch twist bit screeching through a pine shelf like it was sheet metal. A dull bit doesn't just cut slowly — it walks off your marks, burns the wood, and overheats until the tip is gone for good. A sharpener puts a usable edge back on the bits you were about to toss, which beats buying a fresh index box every spring.

Sharpening a twist bit means matching the point angle at the tip with the relief behind the cutting edge, and that's where these machines separate. We've spent the past seven months with 11 sharpeners, from benchtop grinders with a fistful of collets to compact units built for the common sizes. The gap showed up fast, mostly in whether the flutes came out even and whether the manual made sense on a cold first read.

Two things I'd tell a first-time buyer. Most bits come ground at 118 degrees; 135 degrees with a split point is what holds up in hard metal and keeps a bit from wandering, so adjustable angle earns its keep. Collet coverage beats collet count, too — what matters is the sizes you actually snap a bit into. Each pick below earned its spot by putting a real edge back on a bit.

Capacity is what puts this one on top. The 750X takes anything from 3/32 inch to 3/4 inch, and it lets you set the point angle anywhere between 115 and 140 degrees rather than offering a preset or two. Nothing else here reaches 3/4 inch, so if your index runs to 5/8- or 3/4-inch shanks, this is the only machine on the page that will hold them.

The split-point port is the feature we appreciate most, though. A split point keeps a bit from skating when it starts a hole, and the 750X both restores existing splits and cuts new ones, with a push-to-stop guard that keeps you from grinding a split past the point where the bit still works. Carbide, cobalt, black oxide, TiN-coated, and masonry bits all run on the same installed diamond wheel.

Setup is where it asks for patience. Getting a small bit seated so the wheel meets both lips evenly is the whole skill, and the manual assumes more than it explains — work through a handful of bits you have already written off before you touch the ones you care about. Once the alignment clicks, each bit takes seconds and the edge comes out consistent.

Three years of warranty and a 180-grit diamond wheel that arrives already installed suggest a machine meant to live on a bench. If your bits all sit in a folding index that stops at 1/2 inch, the 500X gets there with a shorter learning curve; the 750X earns its keep once your drilling runs to bigger shanks and mixed materials.

Worth Noting

  • Nothing smaller than 3/32 inch fits
Our Verdict

This is the one we recommend for a mixed bit drawer: 3/4-inch capacity, a point angle you can set anywhere from 115 to 140 degrees, and split points on demand.

Drill Doctor 500X Best for Standard Bit Sets

Drill Doctor 500X Drill Bit Sharpener for 3/32 to 1/2 Inch Drill Bits

Standard home kits

Field Score 91/100
Split Point

Bit Capacity
3/32 to 1/2 inch
Point Angles
118 and 135 degrees
Included Wheel
180-grit diamond
View on Amazon

Same family as our top pick, with the ceiling brought down to 1/2 inch and the dial replaced by two choices: 118 degrees for general work, 135 for harder stock. Same 180-grit diamond wheel, same split-point port, same guard against over-splitting. For the bits in a typical homeowner's index, that covers the whole job.

It is the one we hand a first-timer. Setup runs a couple of minutes, the chuck does more of the aligning for you than the 750X does, and the edge that comes off the wheel is consistent enough that you stop bracing for a ruined bit. A bad first session is what makes people give up on these machines, and this one is hard to have a bad session with.

The split point is the place to slow down. It is easy to grind a split deeper than a small bit wants, and a bit taken too far cuts worse than the one you started with — short touches, then check. If your bits grow past 1/2 inch later, a 3/4-inch chuck is sold separately rather than forcing a new machine.

It lands in the middle of what sharpeners cost: well clear of the budget boxes, a long way under the collet machines, and carrying the same three-year warranty as the rest of the line.

Worth Noting

  • Two preset angles, with nothing in between
Our Verdict

If your bits stop at 1/2 inch, this is the one we hand a first-timer: quicker to set up than the 750X and easier to learn on.

VEVOR MR-13A Best for Precision Work

VEVOR Drill Bits Sharpener

Precision shop work

Field Score 87/100
Collets
11 elastic collets
Bit Capacity
3 to 13 mm
Grinding Wheel
CBN, pre-installed
Point Angle Range
95 to 135 degrees
View on Amazon

Eleven elastic collets, sized 3 through 13 mm, close all the way around a bit's shank instead of clamping three jaws onto its flutes. That sounds like a detail and it isn't: a collet returns the bit to the same position every time you re-chuck it, which is what lets you grind, look, and grind again without losing your place.

Behind the collets sits a 120-watt DC motor turning at 4,500 RPM and a cubic boron nitride wheel made for high-speed steel. The body is compact for a bench machine at roughly 11 by 5 by 6 inches, the cover opens so you can clear out dust, and the point angle adjusts from 95 to 135 degrees — so a 135-degree bit stays 135 instead of being reprofiled into whatever the factory picked.

This is the drill bit grinder in the group rather than a sharpening gadget, and we came away treating it that way. Collets and a proper wheel are the two things that separate a repeatable edge from a lucky one, and it has both. Sharpen a whole index at one sitting and the difference shows up in the tenth bit as much as the first.

The ceiling is 13 mm, so a 9/16-inch shank will not fit. For standard home sizes sharpened a few at a time, the 500X is easier to live with; the VEVOR is for a shop that runs through high-speed steel and wants every bit coming off identical.

Worth Noting

  • CBN wheel is aimed at steel, not masonry
  • Heavy at 18.3 pounds on the bench
Our Verdict

We point shops at this one: the collets hold a bit identically every pass, and the point angle runs from 95 to 135 degrees.

AR MR-13A

AR MR-13A – Drill Bits Sharpener

Bits past 1/2 inch

Field Score 86/100
Collets
13 elastic collets
Bit Capacity
3 to 15 mm
Grinding Wheel
CBN
Point Angle Range
95 to 135 degrees
View on Amazon

Thirteen collets running from 3 to 15 mm is more range than anything else here, and it is the entire argument for this machine. If your work runs to bits between 1/2 and 9/16 inch — bridge work, heavy steel, anything with a big pilot hole — the VEVOR's 13 mm ceiling leaves you outside and this does not.

Otherwise it is the same MR-13A pattern as the VEVOR: a DC motor around 4,400 RPM, a point angle adjustable from 95 to 135 degrees, a cubic boron nitride wheel, and an open cover for dust. The two extra collets at the top of the range plus the included collet chuck are what the wider range buys.

For most shops those big collets go unused, and that is why it sits behind the VEVOR here — headroom is only worth having if you will use it. If your bits do run past 1/2 inch, nothing else on this page holds them, and holding a bit properly is the whole game.

Worth Noting

  • CBN wheel suits high-speed steel, not masonry
  • Range above 13 mm goes unused on standard sets
Our Verdict

We keep it for one job: bits past 1/2 inch. The 15 mm collet set reaches sizes nothing else here will hold.

MDPSDS RS-1 Best for Tight Budgets

MDPSDS RS-1 – Drill Bit Sharpener

Tight budgets

Field Score 83/100
Motor
95 watts, 110 volts
Weight
2.59 lb
Point Angle
130 degrees
Bit Capacity
1/8 to 15/32 inch
View on Amazon

The cheapest way onto this list, and it does the job it was built for. A 95-watt motor, a positioning plate that holds the angle for you, and a 2.59-pound body that can live on a shelf until you need it. Bits from 1/8 inch to 15/32 inch go in, and you grind by feel against the plate.

What we like is how little it asks. There is no chuck to align and no split point to set: seat the bit in the plate, touch it to the wheel, check the edge. For a homeowner with a coffee can of dull bits and no appetite for a learning curve, that is most of what the expensive machines deliver.

The catch is the point angle. It is built around 130 degrees, so the 118-degree bits that fill most indexes come off it reprofiled rather than restored, and a 118-degree bit reground to 130 wants more feed pressure and starts a hole harder. Check what your bits actually are before you order — this is the wrong machine for a drawer full of standard 118s.

Wheel and motor life is the open question, and that is the trade for the price; price a spare wheel in when you buy. For occasional sharpening of a small set, though, it puts a working edge back on a bit for less than a handful of replacements.

Worth Noting

  • No slot for 1/16-inch bits
Our Verdict

We think it is the right first sharpener if your bits are 130-degree: simple, compact, and the cheapest way onto this list.

How We Tested Drill Bit Sharpeners

We started with specs rather than star ratings: bit capacity, adjustable point angles, how many collets came in the box, and whether replacement grinding wheels were sold separately. That filtered a long list down to 11 machines spread across price points, which we ordered and set up on the same garage bench.

Every unit got the same cold start — out of the box, manual only — and I timed how long it took to go from unopened to the first sharpened bit. Then I fed each one a coffee can of dull bits ranging from 1/8 inch up to 3/4 inch, twist and masonry, sorting each into the matching collet and setting 118 degrees, then 135 with a split point wherever the machine allowed it. I checked every tip under a loupe for flutes that came out uneven, looked at the relief behind the edge, and then drilled test holes in pine, oak, and a mild steel plate, counting holes until a bit started to smoke.

Because these live on a crowded bench or in a toolbox drawer, I measured each footprint and carried them between the garage and the basement to see what rattled loose. After every 20 bits I checked the wheel for glazing and for how much material it had eaten, and noted whether a replacement wheel was easy to find and reasonably priced — the real value question, since a sharpener that outlasts its wheel is a paperweight. Manuals got graded too: the ones written for someone holding a bit for the first time got used, and the rest went back in the box.

How to Choose a Drill Bit Sharpener

Start With the Bits You Own, Not the Range on the Box

Capacity is quoted as a spread, and both ends matter. The top end decides whether your 5/8- and 3/4-inch bits have anywhere to go; the bottom end decides whether a 1/16-inch bit — the size that snaps first — can be held at all. Several machines start at 1/8 inch and simply have no way to grip anything smaller.

Count your actual bits before you buy. If the drawer stops at 1/2 inch, the 500X covers it and the extra capacity of the 750X never gets used. If you drill concrete anchors or run a hole saw with a 5/8-inch pilot, the bigger machine stops being a luxury.

Match the Point Angle to Your Bits

118 degrees is the general-purpose point on most twist bits. 135 degrees is for harder material and starts a hole with less skating. A split point goes further still, thinning the chisel edge at the tip so the bit bites instead of wandering.

The question is whether the machine holds your angle or imposes its own. A fixed 130-degree sharpener will quietly reprofile a drawer full of 118-degree bits, and they drill differently afterward. Adjustable machines let a bit keep the geometry it was made with; the 750X and 500X cover this with a range and two presets respectively.

The Chuck Is Where Good Edges Are Won

Every machine here grinds the same way: a wheel meets the bit's two lips and has to take the same amount off both. What varies is how the bit is held. Three-jaw chucks with alignment marks are quick and span a wide spread of sizes. Full-circle collets, as on the VEVOR and AR drill bit grinders, close around the whole shank and return the bit to the same position every time you re-chuck it.

If you sharpen the same bits again and again, that repeatability is the feature worth paying for: you can grind, look, and grind again without starting over.

Expect Your First Bits to Be Bad

Nobody sharpens well on the first attempt, and the instructions are often the weakest part of the package. Do your learning on bits you have already written off, keep the touch light, and check the lips after each pass rather than grinding away and hoping.

A bit ground unevenly cuts oversize and burns; a bit ground a little short still cuts. Once the motion clicks it takes seconds per bit, so the patience is a one-time cost rather than an ongoing one.

Wheels Wear, So Price the Replacement

Diamond wheels last a long time and arrive installed on the Drill Doctor machines. Cubic boron nitride wheels, as on the VEVOR and AR, are built for high-speed steel and stay flat. The budget units run abrasive wheels that wear faster, especially if you feed them cobalt bits.

Before you buy, find out what a replacement wheel costs and whether it is available at all — a sharpener with no wheel is a paperweight. On the cheap end of the market, budget for a spare from the start.

Frequently Asked Questions

Final Verdict

The Drill Doctor 750X is the one we recommend: it holds bits from 3/32 inch to 3/4 inch, sets any point angle between 115 and 140 degrees, and cuts split points when you want them. It is the only machine here that covers a full shop index without a second purchase.

Choose the 500X instead if your bits stop at 1/2 inch and you want the shortest learning curve in the group. Go to the VEVOR if you sharpen a lot of high-speed steel and want collet repeatability, and to the AR only if your work runs past 1/2 inch into sizes nothing else here will hold.
