To choose the right drill bit, you need to first consider the material you are drilling. Each material has specific hardness and mechanical properties. That is why there are many different drill bits.
Before choosing a drill bit, the main criteria to consider are as follows:
Drill bit material: High speed steel or tungsten carbide
Mounting: Depends on the machine diameter used
Drill bit type: Twist, step, reamer, center, cone, insert
