It’s a well-known fact that dull drill bits are inefficient, slow, and they can even harm your projects. Therefore, sharpening your drill bits is an essential skill that every DIY enthusiast, professional contractor, or handyman should have. Having sharp drill bits is not only convenient but it also saves you from the cost of buying new ones. In this article, we will explore how to manually sharpen a drill bit using a few basic tools.

Step 1: Gather your Tools

First, it’s essential to have the necessary tools before sharpening your drill bits. So, to sharpen a drill bit, you will need a couple of items, including safety goggles or a face shield to protect your eyes from debris. Next, you’ll need a bench grinder or a sharpening stone, a drill bit gauge, a metal file or sandpaper, and a steel wool pad for finishing.

Step 2: Secure the Drill Bit

Now, you need to secure the drill bit in a vise to protect you from accidental injury when sharpening the bit. You can also use a clamp or a pair of locking pliers if you don’t have a vise. Just be sure to hold securely, so you have a good surface to work on.

Step 3: Determine the Angle

Determining the angle of a drill bit is crucial because it varies from bit to bit, depending on the size, the purpose, and the material you will be drilling. If the angle of the bit’s tip is too steep or too high, it won’t cut through materials effectively, but it will only slip, leaving unwanted marks on your workpiece. Therefore, it’s important to follow the manufacturer’s recommendations for the specific bit you are sharpening.

Step 4: Grinding

After you’ve determined the appropriate angle, you can now start grinding the drill bit. If you’re using a bench grinder, ensure that the tool rest is at a 90-degree angle to the grindstone or wheel. Next, hold the drill bit at the correct angle and grind it lightly against the wheel to remove any chips, dull edges, or burrs. You should apply a gentle and even pressure on the bit as you grind to ensure a smooth and uniform finish.

Step 5: Establish the Chisel Point

After the rough grinding, you need to establish a chisel point on the tip of the bit. Establishing a chisel point helps to reduce the pressure required for drilling, reduces heat buildup, and increases the efficiency of the bit. To achieve this, place your drill bit in the vise, and mark the center of your bit. Then, take your metal file and lightly file the tip of the bit at a 60-degree angle on each side, creating a chisel point.

Step 6: Finishing

Finally, use sandpaper or steel wool to smooth out the entire surface of the bit. Start with a coarse grit sandpaper or steel wool first, then move to a finer grit until the bit is shiny and smooth. You can lubricate the bit with a light oil or silicone spray to prolong its life after sharpening.

In conclusion, sharpening your drill bit is an essential skill that helps to improve your drilling performance and overall efficiency. Providing care to your drill bits keeps them sharpened and ready for use. The steps mentioned above will guide you to manually sharpen your drill bit effectively using the basic tools available. With a little bit of practice and patience, you can have clean and sharp drill bits in no time.
