Material: Carbide drill bits
Drilling steels in general, cast steels, cast iron, chilled
cast iron, malleable cast iron, non-ferrous heavy
metals, non-ferrous light metals, abrasive plastics.
Tungsten steel alloy makes the drill hardness higher, and at the same time it will be more crisp and easy to break. Therefore, tungsten steel drill can no longer be used by hand electric drill, and a stable processing environment should be provided.
