TT Series-Carbide Drills-TOTIME

Features

● Curved cutting edge design disperse the cutting force.it is not easy to cause chipping and wear due to stress concentration,and facilitate chip removal.

● Nano composite Balzers-PT coating .superior wear resistance,longer tool life.

● Specially suitable for hole machining of carbon steel,alloy steel,stainless steel and other materials.

● Deep holedrill series L/D=12-30.
