Drill sharpening with tools or manually. The drill bit is sharpened at a 59-degree angle. The front of the drill bit should be higher than the rear. The center of the drill bit or the center line should be as small as possible.Check out the video and see how I made the sharpening tool. I ended up testing the drill bits. Look who won.
