Tips in Buying the Best Drill Bit Sharpener

Sharpening drill bits is understandably intimidating. The process can get quite tricky, which is why you need a drill bit sharpener that will be able to provide you with the features that you are looking for. Having said that, here are a few more tips you need to keep in mind if you want to buy the best drill bit sharpener:

  • Check how easy it is to use.

Drill bits are small and tricky to align if you are using a drill bit sharpener that doesn’t have good alignment and clamping features. It is a good idea to make sure all these present in the drill bit sharpener you are buying just to make sure you don’t become frustrated and annoyed when trying to align your drill bits. It should also come with a manual that is easy to understand.

  • Make sure it can sharpen different kinds of drill bits.

Not all the sharpeners out there are capable of sharpening all drill bits. If there are specific drill bits that are in heavy rotation in your drilling kit, you would want to make sure the sharpener you are buying can cater to these drill bits. That same goes with different finishes and material used for the drill bits. For instance, if the sharpener has a specific kind of wheel that only caters to carbide, you won’t be able to sharpen your titanium or high steel drill bits without changing the wheel first.

  • The wheel should be durable.

Speaking of the wheel, make sure it does not break at first use. Always look for wheels that can last for hundreds of sharpening jobs, so you are truly getting your money’s worth. If it is a universal type of wheel that can sharpen different bit materials, all the better. If not, look for something that has an easy mechanism to change the wheel.  

  • Look for additional features.

A dirt collection system, back-cut split point system and many are just a few of the useful features you can find in today’s drill bit sharpeners. Decide whether you will want to spend a bit more money on these features or if you want something with simpler and more basic features.
