  • Cutting diameter: 1/8 - 3/4 inches
  • Size: 4.9 x 4.9 x 7.4 inches
  • Weight: 2 lbs

This is not a complete drill bit sharpener on its own, but rather, it's an attachment which helps you to use your bench or surface grinder to sharpen your drill bits, and this assumes you also have a grinder beforehand.

Its basic usage concept is quite simple. You insert your drill bit into this attachment and fix the attachment itself in front of your grinder. Then properly place the clamp in front of your grinder, then adjust its angles and you're ready to start sharpening.

This grinder clamp attachment works with 1/8 to 3/4-inch bits and it's designed for use with OSHA-, ANSI-, and UL-approved surface grinders or electric benches. It's also completely made from metal, so you're sure it'll last very long.

  • Cutting angle: 90 - 150 degrees
  • Cutting diameter: 1/8 to 7/8 inches
  • Size: 14 x 7 x 3 inches
  • Weight: N/A

Tormek is a well-known brand when it comes to grinding equipment. Producing grinding machines for all professions and tools, Tormek also makes high-quality jigs and other attachments, including this DBS-22.

The first thing to understand here is that it's only compatible with Tormek grinders, and as one of the best-rated drill bit sharpeners, its features are really worth its high price.

You get a 4-facet point on your drill bit, which offers you clean, straight holes without walking when there is no pilot hole. The design also makes it easy to create 2 asymmetrical cutting edges. Simply grind one side, flip the jig over, and grind the other.

Tormek's DBS-22 is also very versatile. If you know how to use it, then you can easily custom grind any bit for a particular material or clearance.

Although it's not an automated sharpener, this jig is still an amazingly precise tool for sharpening your bits. You just need to read the instructions and build up a little skill with it and you'll amaze yourself.


  • Produces 2 symmetrical edges that are precisely equal
  • It creates a 4-facet point for ideal drilling performance
  • Adjustable sharpening angles between 90 and 150 degrees
  • Can easily handle drill bits 1/8 to 7/8 inch diameter

  • Cutting angle: 118 - 135 degrees
  • Cutting diameter: 3/32 to 1/2 inch
  • Size: 14 x 12.8 x 7.5 inches

Designed around a diamond sharpening wheel of industrial strength, you can rest assured that it'll last you for over 200 sharpening sessions, and if you should need to change it, the change process is also very easy.

The box comes with a user guide, the pre-installed 180-grit diamond wheel, a 1/2-inch chuck and a wrench for changing the sharpening wheel.

Although this is a very good bit sharpener, its downside is having fewer features and flexibility than Drill Doctor's top-of-the-line model, the 750X, but if you're on a budget and it serves your needs well, then, why not save some money?


  • Will sharpen 118 and 13-degree point angles
  • Can create and sharpen split-point bits
  • Comes with a pre-installed 180-grit diamond sharpening wheel
  • Sharpens twist, carbide, HSS, black oxide, cobalt, tin-coated, and masonry bits

  • Cutting diameter: 1/8 to 3/4 inch
  • Size: 8.7 x 5.3 x 2 inches
  • Weight: 1.4 lbs

If you need a cheap and good drill bit sharpener, then here's something for you to take a closer look at. Weighing just 1.4 lbs, its made from metal and designed for precise bit sharpening.

All you need to do is to install it near your surface or bench grinder, follow the instructions, and you've got yourself an affordable and fun tool to restore your drill bits with.

You can use it to sharpen drill bits from 1/8 to 3/4 inch diameters, and you can do it quickly and accurately, once you've mastered the tool.

#6. Grizzly G1081 Drill Bit Sharpener Attachment

Editor's Rating: 3.9 out of 5 stars (3.9 / 5)

Grizzly G1081 Drill Bit Sharpener Attachment
  • Cutting angle: 41 to 88 degrees
  • Cutting diameter: 1/8 to 3/4 inch
  • Size: 8 x 5 x 1.3 inches
  • Weight: 1.35 lbs

Grizzly's G1081 has the same specs as Woodstock's D4144. It's made using metal, it's about 8 inches tall and it weighs just about the same.

With the Grizzly G1081, you'll also need to already have a grinder in order to for it to work. You install it near your grinder and then use the settings to place your bit against the grinding wheel to get the sharpness you need.

There is an included user manual, but you'll need to focus well to understand the setup and usage. Once you get the hang of it though, you'll find it's a very simple and straightforward method to sharpen your drill bits and save some money.

On one hand, this attachment might not pass as a compact drill bit sharpener, since you need to set it up near your grinder, but on the other hand, it's cheaper to buy up-front and there's no maintenance cost associated directly with it.


  • Can be used for drill bits with 1/8 to 3/4-inch diameters
  • The metal body is strong and long lasting
  • Offered at a very low price
  • Comes with a user manual for set up and operation


  • Requires an extra surface or bench grinder
  • Setting it up needs a bit getting used to

#7. Neiko 10170A Electric Drill Bit Sharpener

Editor's Rating: 3.8 out of 5 stars (3.8 / 5)

Neiko 10170A Electric Drill Bit Sharpener
  • Cutting angle: N/A
  • Cutting diameter: 1/8-5/8
  • Size: 10.6 x 7.6 x 5.3 inches
  • Weight: 4.4 lbs

Neiko is a Chinese maker of affordable tools and lots of other products for the home and garage. This drill bit sharpener from Neiko features a unique design which sets it apart from the rest on this list.

The idea is simple, just stick your drill bit into a fitting hole in the top and the rotating grinding stone inside will sharpen it for you. There are two heads to choose from, with the heads having many holes with labels that show their diameters.

A simple knob on top allows you to adjust the height of the stone, so you can set it exactly to what you want. Each of the heads also comes with its own grinding wheel and an electric motor, while the entire package includes a 6-foot power cable and an AC power adapter.

On the other hand, such a system as this has its issues, because unlike the automatic sharpeners from Drill Doctor, for instance, you'll need some skills to properly sharpen your bits with this Neiko machine.

This sharpener also sharpens at one standard angle only, so you can't select a sharpening angle as you would with a  professional drill bit sharpener.


  • Electric drill bit sharpener is compact and portable
  • Features guiding holes on top to make its use easy
  • Includes rubber feet for stability
  • Comes with two heads for your convenience


  • Only sharpens at one angle, which is not adjustable
  • You'll need some personal effort to properly sharpen your bits

How To Buy the Best Drill Bit Sharpeners

How To Buy the Best Drill Bit Sharpener

A drill bit sharpener is a very specialized tool with a specialized job. This demands a closer understanding of its different features, so you can make the right choice and get a bit sharpener that's perfect for your needs. Following are these features to consider.

#1. Size

There are 2 sizes to consider when you're talking about a drill bit sharpener. The first size refers to the sharpener itself, about how big or small it is, and whether you have enough space for it. Most drill bit sharpeners are usually compact anyway.

The other size refers to the size of the bits the sharpener can handle. This most especially refers to how large the bit holder and the grinding stone are.

You should know that drill bit sharpeners are designed for particular drill sizes, so anything beyond that size will not work. What you need to do, first, is to know the size range of your drill bits, and then begin the search for a sharpener for that size range.

#2. Material

A second consideration is whether the bit sharpener is for your drill bit's particular material. This is because while most sharpeners on the market will sharpen most drill bit materials, some drill bits with special finishes or alloy materials could pose a problem.

So, making sure that your bits are standard is the key here, else you'll have to find a specialized sharpener for your drill bits. Most conventional sharpeners can handle tin-coated bits, masonry bits, steel bits, tin-, cobalt- and titanium-coated bits anyway.

#3. Versatility

A bit sharpener's versatility here refers to how many different kinds of bits it can sharpen. Some sharpeners can work automatically but they'll be limited to only a certain type of bits, while other sharpeners can sharpen more bit types.

Most tools will easily sharpen twist drill bits, but if you need to sharpen a spade bit, then you'll need a more versatile sharpener. A more versatile tool is definitely more valuable in every situation, but you should also consider its extra cost.

#4. Ease of Use

Specialized drill bit sharpeners can have your bit sharp and ready in just a few seconds while sharpening it manually with a Jig and a bench grinder will produce varied results depending on your skills.

It's left for you here to know how patient you are and how much time you can spend to set up and finish the sharpening session. If you don't have the time, automated sharpeners can be your friend.

#5. Grinding Stone

Your grinding stone's quality will help you to know how long it'll last, while its grit determines how sharp, or abrasive, it is. You need a stone with a grit over of 100 or more, and if you can, get diamond grinding wheels because they're simply the best.

#6. Brand & Warranty

Buying a product from a well-known brand is always a smart thing to do. With drill bit sharpeners, well-known brands include Drill Doctor, but there are also other reputable brands, both with standard and specialized bit sharpeners.

For warranties, more is always better, so while considering which sharpeners to buy, the one with a longer warranty always gets an extra vote.


If you had any doubt about your blunt old drill bits before, you should have made up your mind by now to do something worthwhile and sharpen them by yourself, instead of just throwing them away and getting new ones.

Sharpening your drill bits by yourself not only saves you money, it's also an interesting experience that brings you closer to the world of tool making.

As we reach the end of this drill bit sharpeners review, remember that the final choice between a full drill bit sharpening solution and an attachment, or between precision and a budget sharpener, is yours to make.
