High rigidity tool structure reduces tool vibration；Peripheral edge and ball edge can realize seamless connection, proper center design of ball edge greatly improves surface quality; ultra-fine grain cemented carbide substrate with excellent wear-resistance, nano-level coating ensures excellent wear-resistance and thermal-stability.

bolt-hole making——SU series stepped drill

Only one operation can finish hole-making and chamfering

Drilling for heat dissipation hole—— solid carbide drills

heat dissipation hole

PC series drill with straight flute,excellent conductivity, good rigidity, higher hole quality.
