Plus - Reducing it’s overall life and making it harder to maintain stability. If the sides are not symmetrical this puts further mechanical stress on your drill bit. The reason for this is because the drill will be rotating around the chisel point (tip). You must ensure that as you are sharpening your drill which shall be explained below, you maintain symmetry on both sides. See the image below and lets discuss these. No matter which method you use either a drill kit or using a grinding wheel without any support there are primarily 3 things you must get right to ensure a solid drill finish.
3 key things you must get right to sharpen you drill bit correctly In my opinion, these drill bit kits are not really required, especially if you have a grinding wheel slot that can maintain the an angle with some flexibility to allow you to rotate the drill bit a little for smooth sharpen. It’s a mechanical looking contraption that is designed to hold your drill bit at a specific angle to ensure that you can have nice and smoothly sharpened bits. If you go to any hardware store or convenience store that sells drill bits, you will usually also find a section that sells some form of drill sharpening kit. Drill bit sharpening kits (what is all the fuss) Now that you know this to get your drill bit back into tip top shape all you really need to do is restore the drill bits tip back to the original 118°. Therefore when your drill bit (which is typically high speed steel) loses it’s ability to drill effectively and thus becomes dull, it is because technically the angle has become reduced. Many years of research have provided that the 118° angle is optimal. The flat edge material would just heat up quite a bit and not get very far into the metal or wood. Infact, I can tell you what would happen. The reason for this is simple the surface area for the torque is far to large and dispersed to create any sort of penetration through the material. Let’s take a look at an extreme case, image you tried to drill into a piece of stock material with a flat edge, you would not get very far no matter how much speed you rotated it. But you might be thinking what is a dull drill bit anyways? However, as you already know when drilling into steel or metal the high speed steel will still go dull.
