Best Drill Bit Sharpener: 4 Products You Should Totally Own


A dull drill bit benefits no one. It should always be sharp so you can work efficiently. To easily maintain this type of tool attachment, get your hands on the best drill bit sharpener money can buy.

Our Pick: Drill Doctor 350X Drill Bit Sharpener

Drill bit sharpeners normally can’t match ALL size options. That’s why you should consider your bits’ dimensions first before buying a sharpener. Since we can only choose one product for the top spot, we selected the Drill Doctor 350X Drill Bit Sharpener because of its standard features.

This device can sharpen twist bits measuring 3/32 inches up to 1/2 inches. It can also sharpen drill bits of different styles and materials – even the ones made of lighter metals.

Speaking of materials, we should also focus on the sharpener’s components. The diamond sharpening wheel is so strong that it meets industry standards. It won’t warp or deform despite heavy use.

Since overheating is a concern to avoid affecting the bit’s quality, this machine has a design that can cool itself. The bit won’t get hot, which preserves durability made possible by tempering.

If you still have a lot to learn about sharpening drill bits, you should pick a user-friendly option. This sharpener is ideal for beginners because it doesn’t require an alignment port.

All you need to do is keep the bit secure and move the chuck. Just let the V-block jaws hold it. These jaws are so well-designed that they can even hold small bits.

When it comes to controlling the chuck, simply turn it in an even number of half turns. One of your goals is to ensure an accurate 118-degree angle.

Runner Up: Tormek DBS-22 Drill Bit Sharpener

With its four-facet point, Tormek DBS-22 Drill Bit Sharpener ensures stability which leads to precision. It will move the bit’s point to a really secure chisel edge. The result is symmetry, an essential factor for efficiency and longer lifespan for the drill.

When it comes to angles, this sharpener focuses on the range between 90 and 150 degrees. In addition, you’ll be able to adjust the optimal clearance angle based on requirements to seven, nine, 11, or 14 degrees.

Regarding size, the holder can sharpen drill bits as small as 1/8 inch. It can also hold bigger bits measuring 7/8 inch at most.

Also Great: General Tools 825 Grinding Attachment

One of the most versatile options out there, General Tools 825 Grinding Attachment has an adjustable angle gauge to match any drill bit. For symmetry, it has a neck that pivots to easily grind the bit on both sides.

Since this product works well with a surface or electric bench grinder, it is ideal not just for homeowners but for professionals as well. It may look complicated, but it quickly gets the job done. Just be patient with the user’s manual.

Budget Pick: Woodstock D4144 Drill Sharpener

Despite being the most affordable one here, Woodstock D4144 Drill Sharpener is still hard to beat when it comes to efficiency and precision. It is perfect for 1/8-inch to 3/4-inch drill bits.

Just like standard sharpeners, this device is adjustable, too. It will allow you to set different angles for the drill bit’s point.
