Wide Applications
Suitable for processing through holes or shallow blind holes . Used for drilling and tapping aluminum, stainless steel, copper, hard plastics, etc..
Recommended feed rate: general steel: 6-15m/min; harder steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. The torque caused by too fast feed speed is too large, which can easily cause the tap to break.
First drill the hole with twist drill, and then use the taps tapping. Tapping angle should be vertical 90 degree and keep stable.
