Modified fish-tail point eliminates backside breakout and splintering
High flute volume supports high feed rates / chip loads
Cutting edge geometry virtually eliminates chatter at high feed rates
Flute geometry enhances rigidity for more accurate, single pass cutting at high chip loads

Stub End-mill Tip

LPKF and T-Tech users must specify the make and model number of their CNC routers to insure that the rings are properly positioned!

Use a good, water based cutting fluid to improve finish and reduce tool wear.
