To sharpen drill bits, start by examining it, making sure to examine the whole cutting edge, right to the outer edge. Then, since you may be using a grinder or belt sander, consider wearing a lot of PPE, such as goggles and gloves. Now that you have everything ready, it’s time to grind the drill tip. Turn on the bench grinder and hold the cutting edge precisely parallel to the front of the grinding wheel. Slowly, carefully, move the bit until it contacts the wheel. Do not turn or rotate it, simply keep it straight and held at a 60-degree angle. Hold it against the wheel for no more than four to five seconds. When satisfied with the point on the first side, turn the drill bit 180 degrees and use the same process for the opposite side of the tip. Once you’re confident in the sharpness of the bit, insert it into your drill and begin drilling. It should ‘bite’ the wood right away with minimal pressure.
