We get asked many questions on this website about drill bits. One of the most popular questions we get asked "Is a drill bit sharpener worth the money?" Drill bit sharpeners cost anything between £18 -100 depending on the quality of the sharpener that you want to buy.
Something like a basic Silverline drill bit sharpener costs around £20 whereas something like the Drill Doctor drill bit sharpener will cost pretty close to £100. So clearly, not all drill bit sharpeners are made to the same standard, and the quality of the engineering and effectiveness of these is massive.
A drill bit sharpener is worth buying if you are a serious DIY person who invest in good quality drill bits, or a professional such as a woodworker or a contractor. Over time a drill bit sharpener will keep your bits in the best condition and also extend their lifetime.
That said, we think a slightly better way of answering this question really comes down to how much use the drill bits you own are actually going to get.
Understanding Drill Bit Use
Some home owners will never use a drill or drill bits as they prefer to pay other people to do work around their home. Likewise some people hate the thoughts of any type of DIY so again will not ever have a need to buy a sharpener.
The Casual DIY Person
There are plenty of casual DIY people who are happy enough to put up a shelf, assemble some furniture and when required to drill the odd hole or two. They will likely own a drill/driver and a few drill bits, usually bought in an inexpensive drill bit and screwdriver bit set.
They may be tempted to buy a drill bit sharpener, but we would advise them not to do this. Typically the drill bits they own will last them for a long time if they are only being used a few times a year. When a particular drill bit gets worn out, it will only cost a few pounds to buy a replacement bit. That will always be cheaper than buying a sharpener.
The Serious DIY Person
Then we have the serious DIY person who is always doing jobs and tasks around the home, garden and yard and uses a drill on a fairly regular basis. By regular we mean a few times every month. That type of person is always willing to spend a little extra money to buy better drill bits in the first place. If you are prepared to do that, then you will also be more willing to keep them sharp, so as they do the job when you need them.
The Professional/Contractor
The professional or trades person will definitely benefit from buying and owning a drill bit sharpener. At the end of the day they will know the pitfalls of buying cheap drill bits. Cheap drill bits do a really bad job at drilling holes and they quickly become worn out and useless.
They tend to buy much better quality drill bits which of course cost more. By keeping them sharp it means that they can work faster. It also means the bits will last longer. Finally in the longer term they save money as you don't have to constantly keep buying new drill bits.

Sharpener Buying Tips
We always like to include some buying tips based on the information we found when doing our research.
Spare or Replacement Grinding Wheels
If you use these often enough the grinding wheel will wear out. We found that with the cheaper models that we couldn't find where to buy spare grinding wheels. That is a big concern as the sharpener essentially become useless after that. The better brands like Sealey and Drill Doctor all have replacement parts.
Masonry Drill Bits
If one of your concerns is sharpening masonry drill bits then only the Drill Doctor sharpener can do that. That is because of the cutting angle of 118 degrees.
To summarise the reality is that for most people they will never need to buy a drill bit sharpener. That is because it will simply never need to be used.
For those who do a lot of DIY around the home and garden, then if they do a lot of drilling, a drill bit sharpener would be a very good buy for them. They keep your drill bits sharp and in good condition and ready for use as and when you need them.
For most professionals they too would benefit from a drill bit sharpener for the same reasons as we have explained above. Professionals and contractors do tend to buy better quality drill bits as they have to work quickly, so there is even more reason to look after them.
Many of them will however not do this due to perceived time restrictions. They pick up drill bits as and when they need them. If they took 15 minutes and had the right drill bit sharpener, then they could easily sharpen all their bits.
