1. Remove the drill bit from the drill chuck so that it is much more convenient when grinding, and it is also the correct operating procedure. It is not advisable to grind the drill bit with a pistol drill.
2. Grind the drill bit in the upper part of the grinder. When grinding, make the bit of the drill bit parallel to the grinding wheel of the grinder, and then grind it on the grinding wheel.
3. It is recommended that the right hand be held at the end of the working part of the drill bit, and the left hand should hold the tail of the drill bit. While grinding, keep the position of the drill bit in the right hand, and move the tail of the left hand slightly up and down. Note that the movement does not exceed the height of the drill bit.
4. Be careful not to turn the drill bit during the grinding process, and grind one edge and then rotate the other side of the knife edge by 180 degrees. Finally, the knife edge grinding is repeated in this way.
5. After the two edges are ground, the chisel can be ground. The method is to grind the two sides of the middle into a pointed tip, the specific form is the same as the center hole.
Grinding holes according to the above precautions can meet the standards we need, so that the drill bit is round when machining some thin iron plates. Also be sure to pay attention to safety when grinding, do not just disassemble the tool.
