Types of Drill Bit Sharpeners

  • Hand Drill Bit Sharpening

Drill bits can be sharpened by hand using a bench grinder. This requires some serious mathematics to get the angle right and a skilled hand. Unless you are highly experienced in this regard, I would not recommend this method. It works but is not easy to do. Apart from the skill need it takes quite some time to do and you run a high risk of ruining the drill bit altogether.

  • Sharpening Jig

This is an economical way to make the job easier and more accurate. The Woodstock model we feature later is a perfect example of this type of drill bit sharpener. They work with your bench grinder and take the guesswork out of sharpening bits.

They are useful and great value for money but nearly as simple and convenient as an all in one automatic drill bit sharpener. There is still more skill and effort required and they will take a bit of time to set up.

  • Automatic Drill Bit Sharpener

This is the fastest and easiest way to keep your drill bits sharp and working at their best. There are a number of options available and Drill Doctor is clearly the leading brand. These machines are compact and fast and easy to use. There are a number of options to choose from depending on your needs and your budget.  


Buying guide – What you need to know

As great as a drill sharpener is, there are a few points to consider before rushing out and buying one. Here is what you need to take note of:


While you want a frill sharpener that is stable and sturdy, you do not want something that takes up a lot of space in your workshop. A drill sharpener is not something you will be likely to use every day so a lightweight compact option is ideal.

Fortunately most of them fit this description and certainly, those that we reviewed are all easy to store. One thing to note with the Woodstock is that you will need space available next to your bench grinder.

It is also important to be aware of the size drill bits each machine can handle to ensure you get one that suits your requirements


Speaking of requirements, you also want to ensure the drill bit sharpener is suitable for the type of metal or coating used on the drill bits you generally use. The drill bit sharpeners we looked at all make use of a sharpening wheel that is studded with diamonds. This makes it suitable for most metals including cobalt and titanium.

Ease of Use

The whole point of getting a drill bit sharpener is to make the process easier so be sure to check how user-friendly the model is. The Drill Doctor options are extremely easy to use you will soon be using them like a pro. The Woodstock requires a bit more getting used to but is still easy enough.

All of the models we reviewed come with excellent instructions.

Although using a drill bit sharpener is much easier than doing it by hand or using a grinder, there are still some complicated mechanics that you have to follow to ensure that you’re getting the right results.
