Best Drill Bit Sharpeners in 2027

The Drill Doctor 750X leads our ranking for this keyword. It sharpens bits from 2.38 mm to 19.05 mm. That is 3/32 to 3/4 in, which covers most twist bits in a home or shop set. It also starts smaller than the three 3 mm models, so tiny bits are not left out.

Angle control matters most here. The point angle adjusts from 115 to 140 degrees, and 140 is the highest upper limit in the group. You set it to match the material you drill. It also creates or restores split points, and the Push to Stop port helps prevent over splitting.

It restores carbide, cobalt, high speed steel, black oxide, TiN coated and masonry bits with a diamond wheel. A 180 grit wheel comes installed. The kit adds a 3/4 in chuck, a carrying bag, a wheel hub wrench and a 6 foot cord. It carries a 3 yr warranty. The maker lists the footprint as 11 × 5.75 × 6.5 in, so it fits on a small bench.

The Drill Doctor 350X ranks second. It sharpens bits from 2.38 mm to 12.7 mm, or 3/32 to 1/2 in. That suits the twist bits in a typical household case. Larger bits are out of reach, since the top size is lower than on the 750X and on the models that list 20 mm.

A diamond wheel does the grinding, and the listing says it handles high speed steel, masonry, carbide and TiN coated bits. On Chuck Alignment is meant to simplify setup. V Block chuck jaws help keep small bits from twisting while you sharpen. Those features matter because alignment decides how even the cutting edge comes out.

The maker does not publish a point angle range, split point support, angle adjustment or warranty for this model. If you need set angles or split points, check the listing first. It lists 2.33 lb and a footprint of 4.5 × 6.75 × 12.5 in, so it is easy to store.

The VEVOR MR-20G ranks third. It handles bits from 3 mm to 20 mm, and it ties for the largest top size in the group. It comes with 18 collets, one for each whole size from 3 to 20 mm, plus 2 chucks. A collet that fits the shank closely helps hold the bit true while it is ground.

Point angle adjusts from 95 to 135 degrees. That range starts lower than the 750X but stops short of its 140 degrees. You can also set the lip relief angle with positioner pins, and the listing mentions 4 types. Two wheels are offered, CBN for high speed steel and SDC for alloy tungsten steel.

It is a bench machine. It lists 20.1 lb, the heaviest of the models that list weight, and a footprint of 11.4 × 5.7 × 6.3 in. The motor runs at 4500 RPM, the highest listed speed. The maker does not publish split point support, masonry capability or a warranty.

The Drill Doctor 500X ranks fourth. It sharpens bits from 2.38 mm to 12.7 mm, which is 3/32 to 1/2 in. A 3/4 in chuck is sold separately if you need larger bits. For small and medium twist and masonry bits, the standard range is enough.

The point angle is not adjustable. You choose between two settings, 118 degrees for general work or 135 degrees for harder materials. That gives a stated range of 118 to 135 degrees. Fewer settings mean less to adjust, but you cannot dial in an angle in between.

Split point sharpening is included. It can create or restore split points, which helps reduce walking when you start a hole. The Push to Stop port helps prevent over splitting. The kit has a 1/2 in chuck, a preinstalled 180 grit diamond wheel, a wheel hub wrench and a 6 foot cord. The warranty is 3 yr.

The AR MR-13A ranks fifth. It covers bits from 3 mm to 15 mm with 13 collets, one for each whole size in that span. That is a smaller range than the VEVOR and PreAsion MR-20G units, which reach 20 mm. It also cannot sharpen bits under 3 mm, where the Drill Doctor models start at 2.38 mm.

The grinding wheel is cubic boron nitride, listed as CBN. The listing says the surface finish rivals new bits and that drilling accuracy stays within 0.1 mm. Point angle adjusts from 95 to 135 degrees. Those are the maker's claims, so treat them as listing information, not proof.

The motor runs at 4400 RPM. The listing mentions an open-type cover that opens for dust cleaning and an all-iron structure. A collet chuck is included for holding bits. The maker does not publish weight, dimensions, split point support, masonry capability or a warranty, so check those before you buy.
