Note: Drilling holes of different materials, the drilling table needs to be controlled different speeds when used, especially when drilling hard steel to avoid the drilling speed being too fast, causing the drill bit to burn out at high temperature. When using the product conditions, you can add coolant or water to reduce the temperature appropriately.

Product common sense: Diamond bits are installed on a fixed platform drill work. It can be used longer than ordinary hand diamonds.
