Best Drill Sharpeners - Buyer's Guide

size

Choose a drill bit sharpener that fits well with the available space. Besides, you don't want to buy a tool that will take much space on your workbench, leaving you with no room for other things. Also, the size of the tool determines its weight. This means that a big sharpener is most likely heavy, and you don't need to be carrying a heavy object around any time you need it. Moreover, check the size of the drill bits it can sharpen to establish if it's going to be of use to you. You can check this by ensuring your drill bits' diameter fit the sharpener you intend to buy correctly.

Material

It would be better if you chose aluminum or silicon carbide durable elements to ensure your choice of sharpener lasts long. Better still, Borazon and diamond grinding wheels are among the most rigid materials in existence. This way, you will buy and never think about replacing it anytime sooner.

power Source

There are two types of drill sharpeners; manual and electric. Lately, electric sharpeners are better because of their powerful, fast, and accurate performance. However, the electrical model limits you to working near a socket. Therefore, make sure your working space is close to a socket. Conversely, manual sharpeners are easily portable as they need no connection to a power outlet. Make sure your choice works best for you whenever you need it.

versatility

Most probably, you need more sharpening items in your home and not just the drill bits. Therefore, you need to settle for a versatile tool in sharpening more items, either household or even farm tools. Besides, buying a multi-functional sharpener gives you value for your money. Also, ensure it comes with all the necessary accessories to sharpen all the tools you need, from hard ones to the soft and delicate ones.

bit placement

Defining how powerfully the bit will sharpen, correct placement is vital to the sharpener's overall performance. Some have a hole in the middle, making the abrasive surface move circularly around it. Also, the bit locks into the machine. The result comes from how firmly it holds the bit. Also the amount of space between the sharpener and the bit is a determinant. However, this is a standard feature across most drill bit sharpeners, but others have more resistance to slipping and vibration.

Best Drill Sharpeners - FAQs

How does a drill bit sharpener work?

These are the best and easiest way to sharpen drill bits. They deliver quick work from something that would take a long time to do using your hands and still save you money from always having to replace your drill bits. Set your drill bit sharpener at diverse desired point angles to grind down your dull drill bit and prolong its use.

Do you need a drill bit sharpener?

Same as all the other cutting tools, drill bits can also become dull and blunt. Besides, old and used up drill bits will not deliver clean and precise holes when working. Like a dull knife, a blunt bit can also be a safety risk due to higher chances of slipping. But one of the primary reasons for having a high-quality drill bit sharpener is because it will save you numerous trips to the store to ensure your project moves as desired.

Can you sharpen drill bits using your hands?

Yes, but it is not an advisable move. If need be, you can try sharpening your drill bits by hand with a belt sander or a bench grinder. However, this will most probably not be appropriate to deliver precise cuts compared to what a top selection bit sharpener can provide.
Moreover, if you sharpen your drill bits by hand, you need to wear safety gear, including glasses and protective clothing, because chips of metal can fly off into the air and your eyes. You must also be watchful of where to place your hand, so you don't trap and hurt your finger on the sanding belt or grinding wheel.

What is the best angle to sharpen a drill bit?

For a hobbyist, it is not so severe whether the point angle is 118 or 120 degrees. The chisel edge has to be at 55 degrees to the central cutting edge.
