Welcome to our review of the best drill bit sharpeners available. Drill bits are tools that have a pointed end used to drill holes in various materials. They’re usually made of high-quality metal and then coated with a hard substance such as tungsten carbide or cobalt, making them more durable and less prone to wear over time.

Twist drill bits can either be single-ended (with one point) or double-pointed (split point bits). Double-pointed ones tend to do better on the stricter cutting surface, but they also break much quicker than single-ended ones, so it’s essential to use a sharpening tool regularly to keep your sharp drill bits like new!

Having the capacity to prolong the life of your tools means you get much better value from your initial purchase. The excellent idea is to sharpen your dull drill bit, and the good news is there are specific tools that allow you to do that.

It’s not that easy to figure out what is a good deal (or not!), and there is much conflicting advice out there. Some online product listings are scant on details and leave you wondering if the sharpening device is suitable for you.

Here at Walts DIY, we firmly believe you can make the right purchase if you have the correct information. We have done all the hard research work for you and have compiled a list of the top drill bit sharpeners on the market today.

What to consider when buying a drill bit sharpener

Drill bits are not affordable tools, but they get blunt quickly from drilling through metals, wood, and other materials. It’s therefore essential to have an excellent drill sharpener to avoid purchasing new drilling bits every time. There are a few factors to consider when shopping for the best drill bit sharpeners because they are not all the same. Here are some factors to consider.


Most drill bit sharpeners in the market are designed to handle only small to mid-range drill bits. It’s, however, a wide monetary choice to purchase a sharpener that can handle all the bits in your home or workshop to avoid buying different sharpeners for different bits. Bits over 1/2-inch are costly, meaning you won’t have a budget for them when they are blunt. It’s, therefore, essential to find a drill bit sharpener that you can use for them.

It’s also crucial to remember the small drill bits. Small bits are affordable depending on the material, but they dull very fast. It’s, therefore, crucial to find a suitable drill bit sharpener for them.

Power source

There are two main types of power sources for drill bit sharpeners; drill powered and plug-in electric. What does this mean? Plug-in electric sharpeners mostly come in benchtop sharpeners or adapters. These tools are lightning quick and 100% accurate. You are guaranteed exceptional results with plug-in electric drill sharpeners. The only problem with these tools is that the grinder attachment may become misaligned with the grinder. A quick fix would be to check for angle accuracy before use.

Drill-powered sharpeners are a lifesaver for worksites and places without electricity. You don’t have to stop working due to blunt drill bits. These sharpeners are not as accurate as electric-powered plug-in sharpeners, but they get the job done.


Versatility refers to the number of drill bits a drill bit sharpener can sharpen. Different drill bits are depending on the job they handle. For instance, wood drill bits have very aggressive cutting edges to cut through the wood effortlessly, while bits used for metal are a bit flat-angled to take off small bits at a time to avoid chipping the bit. 

The angled cutting edge of the drill bit will determine the sharpener to be used. Although you can sharpen all drill bits to one angle, retaining the original angle is better. A versatile sharpener that you can adjust to different drill bits is best for someone with multiple different drill bits. The standard angles of bits are between 118 and 135 degrees so look for a sharpener between the two angles for versatility.

The material of the drill bit sharpener determines the durability and optimal functionality of the tool. It’s, therefore, crucial to choose a suitable material. There are different materials used to make drill bit sharpeners. If you own a small workshop or you are just a homeowner looking for a drill bit sharpener for your home-use drill bits, a standard tool will do. Standard drill bit sharpeners are effective when used on drilling bits made of cobalt and steel. The standard grinding wheels do a perfect job with such bits.

If you own high-end drill bits made of carbide, a standard drill bit sharpener will not rise to the occasion. Carbide used in high-end drill bits so very hard. It can only be sharpened correctly and efficiently by diamond grinding wheels. You will, therefore, need a drill bit sharpener that comes with a diamond grinding wheel or a bench grinder that is compatible with a diamond wheel for the best results. Bear in mind that a top-spec diamond sharpening wheel is expensive, and we recommend that most people look at a cheaper alternative, such as the three we have reviewed.


Even though it may seem like a non-issue, the brand is very crucial in ensuring quality. Go for a sharpener from a reputable brand. Some brands have been in the market for years, meaning they have experience in making high-quality sharpeners. Although some big brands may be costly, quality is guaranteed.

A warranty should back a reliable drill bit sharpener. If the drill bit sharpener gets damaged or becomes faulty, the warranty should cover you. A reliable brand with confidence in its products should have at least a one-year warranty.

Even with the above factors to keep in mind, you may still wonder about the best drill bit sharpener to purchase. Drill bit sharpeners are not the cheapest either, so it’s best to maximize utility on whichever you choose. Here are some helpful tips when buying a drill bit sharpener.

  • If you don’t use your drill bits constantly, a drill-powered sharpener should do just fine. Drill-powered sharpeners are cheaper than plug-in electric sharpeners. A drill-powered sharpener, though not as accurate as an electric plug-in counterpart, should put an edge on the drill bits for a decent job.
  • If you already own a bench grinder or belt sander, there is no need to go for a new drill bit sharpener. An attachment should sharpen just fine. Bench grinder attachments are less expensive and get the job done accurately. It may take longer to set up, but you will have saved your money and achieved the same quality and angles once the setup is complete.
  • An electric plug-in model is the most fool-proof and accurate model. If accuracy and ease of use if non-negotiable for you, then an electric benchtop model is the sharpener you are looking for. These models tend to be pricier, but they are fast, accurate, and easy to use even for someone who has not used them before.
