What is a Drill Bit Sharpener?

A drill bit sharpener is a mandatory tool for all mechanical and electrical experts. It comes in both manual and electric forms to sharpen drill bits. The sharpener has a heavy metal wheel in it, which rotates to rub against the surface of the drill bits. 

It makes the twists on the drill bits sharper and more angled. This is why there are some metallic shavings when you sharpen your drill bits in a sharpener. 

These sharpeners have specific jaws and securing points in them too. This makes them easy to use, so a drill bit sharpener can make your work easier.

How Do I Choose a Drill Bit Sharpener?

Choosing the right drill bit sharpener is the key to getting the most out of it. The better it is, the more useful it will be for you. Considering this, we have brought you a list of features that you have to look for while getting one for yourself.  

Size Range

The size range of drill bits that a drill bit sharpener is compatible with affects its usability. Usually, sharpeners support standard-sized drill bits, but some also allow you to customize them. So, consider the size of your drill bits and then see which sharpener suits them. 

Wheel Type

The wheel type also has a great impact on the way it works. The wheel has to be strong enough to fight off all the opposing force from the drill bits. This is important as the wheel can wear out too, and then it won't be able to work for you.


The efficiency of a drill bit sharpener is important to consider as well. It directly affects the amount of power that it consumes and the loss of electricity too. So, go for a model which does more work in lesser time and with lesser power consumption.

Review of the Best Drill Bit Sharpeners

So far, we have established that a drill bit sharpener is a necessity for you if you want the bits to be sharp. It not only makes them shinier but also smoother to work with. This is why we have brought you a list of the best drill sharpeners to help you choose the best one.

What Recent Buyers Report

Recent buyers had a great experience with this drill bit sharpener. It helps them set the right angle for preventing any accidents. In addition, they liked the way they could control the amount of metal wastage with this one. Buyers also reported greater ease of use due to diverse angling.

Why it Stands Out to Us

It stands out to us due to its aluminum point angle shuttle, which helps in positioning the bits. The accuracy of the angle then leads to sharper bits, which look new. The power cord is also amazing at the length of 6 feet and ensures ease of use. You can easily connect it to a power plug and work remotely. 

Who Would Use This Most

This is most useful for professionals who have multiple drill bits that need frequent sharpening. The sharpener can deal with heavy-duty usage, so you do not have to worry about its life. It can take up to dozens of drill bits a day, so you can use it in professional settings easily.

Bottom Line

The bottom line on this one is that it is one of the best drill bit sharpeners on the market. The aluminum body makes it strong and ensures that it can deal with multiple weather conditions. It can also take heavy metal alloy bits, so you get to use it extensively.

People who bought this amazing drill bit sharpener recently gave positive remarks about it mostly. They loved it for the efficient sharpening of their old and new drill bits. Buyers also liked the size range it could cater to as it enabled them to sharpen all their standard bits.

Why it Stands Out to Us

It makes it to our list as the runner-up because of the Borazon wheel. This wheel helps it sharpen heavy alloy bits, which exhaust other drill bit sharpeners. Moreover, its construction has a cubic Boron Nitride wheel, which has a longer life and multiple functioning. 

Who Would Use This Most

This drill bit sharpener is more suited to the needs of hobbyists as they have lesser use for it. However, it cannot keep up with the heavy-duty usage of a professional's work. So, get it if you have light and less frequent use for it as it will help you sharp well at a low price.

Bottom Line

In our opinion, it is the best drill bit sharpener for light-duty usage. Yes, you can use it to sharpen heavy metallic alloys drill bits, but you won't be able to use it very frequently. This will exhaust the sharpener, and you will have to look for another one.
