There are a lot of things to consider when shopping for a drill bit sharpener. One reason for this is they’re all very different so you need to make sure you get the right one. Before you buy, here are some things to think about.
Do I Really Need a Drill Bit Sharpener?
This is the first thing you should ask yourself before you buy any tool. A lot of times, you probably don’t really need it, especially when it comes to larger industrial tools. Now, that’s not to say you don’t want it. But want and need are two very different things.
A drill bit sharpener is different because it is genuinely very useful. The truth is, anyone who uses a drill on a regular basis will benefit from a drill bit sharpener, especially if you use multiple bits or you invested in higher quality ones.
Think about how many drill bits you go through and how much it will cost to replace them. If you do a lot of work professionally or even in your workshop at home, it could get quite pricey, especially if you have a lot of high-quality, specialized bits. The cost of a sharpener is likely much less than what you will spend on drill bits over the course of your lifetime. It won’t take long to make back the cost of the sharpener.
What Factors Should I Consider?
Before we get into the details, it’s important to realize that these tools aren’t universal, meaning that one tool will not work with every single drill bit. So, before you get started, you have to know a few things about the drill bits you use. Specifically, the size and material. If you use a lot of different kinds or multiple drills, have some idea of the range of sizes they cover.
Basically, you need to know exactly what bits you need to sharpen before you choose the right tool to sharpen them. Once you know what you need, keep the following key features in mind.
First, make sure the actual size of the sharpener is going to comfortably fit in your workspace. They come in a range of sizes from handheld to large, industrial sized.
Another size related feature to focus on is the size of the drill bit, as we mentioned earlier. The most common drill bit sizes are 1/16 to 1/4″ and most large sets will also include increments up to 1/2″ thick. These sizes are more than enough to cover just about any job you’d do around the house.
Something else we want to mention about size is that these machines are great for the standard, most common sized bits. When it comes to really small bits or very large ones, make sure you get a better quality machine. Not every has a use for bits of this size but, if you do, it’s worth investing a little more so you know it’s done right.
You have to consider both the material of the bit and the material of the sharpening wheel. Most standard wheels will be able to tackle basic bits made of high-speed steel or cobalt. These are bits used to drill into soft steels, woods, and plastics and are what the bits you use at home are typically made of. At the minimum, you need a grit of 100 or more. One thing to keep in mind is the higher the number, the more abrasive it will race.
If you have a carbide bit, a standard sharpening wheel probably isn’t going to cut it. Carbide is the hardest drill bit and it’s also very brittle so, you can see how a regular wheel isn’t ideal. If you use carbide bits, make sure you get a sharpener that comes with a diamond wheel or has the option to upgrade to one.
One thing to mention, if you’re using coated drill bits, be careful before you try to sharpen them yourself. For example, titanium or cobalt coated drill bits will lose their coating if you sharpen them using one of these tools.
Versatility only matters, well, as much as it matters. What we mean is, if you’re in the market for something that will work well with your basic home drill, most common sharpeners will do. If you tend to use more than one drill, such as a milling machine, or a wide range of different kinds of bits, make sure you get a sharpener that’s versatile enough to handle them all.
If you want something that’s really versatile, there are some pretty high-tech options available. To see what we mean, take another look at our top pick. If you have a lot of different tools that require sharpening, it might be worth investing in a more versatile machine. For example, if you use a lot of chisels for woodworking or furniture building, a machine that can sharpen everything will come in really handy. On the other hand, if you don’t need something that versatile, stick with something a little more basic.
Most of these sharpeners are automatic. You change the angle and the depth and various settings, insert the bit, and it sharpens it to your specifications. You have to have a steady hand and a good grip but the process is pretty simple. There are some other options, though, that you might want to consider.
Basically, if you’re using a simple drill and want something simple, there are simple handheld tools available that actually use your drill to power the sharpening wheel. There’s also a model that uses a bench grinder as the wheel and simply holds the bit at the correct angle so you can sharpen it easily using something you already have.
The more bits you work with and the more frequently they need sharpened, the more sense it makes for you to invest in a more high tech machine. Whether you want to start with something basic and upgrade later or just start with something you can grow into is up to you.
Drill bit sharpeners can bring your old drill bits back to life so that you no longer have to keep replacing them. In the long run, it will save you money. There are a lot of options out there that can do just about anything you need them to.
