Silent roughing with 2-3 times faster metal removal rates compared to 4 flute HPC style end mills.
First choice for maximum metal removal rates in low carbon steels alloy steels pre-hardened steel (up to HRC45) and cast iron
Strong core and special cutter geometry reduce harmonics and eliminate vibration
Premium micrograin carbide substrate combined with X1100 coating improves performance
Large depths of cut plus high feed rates reduce cycle times
Variable pitch reduces vibration and cutting forces allowing large depths of cut and high feed rates
Special uneven ripper tooth design breaks swarf down improving chip flow
Corner radius geometry strengthens cutting edges reducing risk of premature failure
Excels in slotting, shouldering, plunge and pocket milling due to strong tooth end design
GMG40 & GMG41 Series
UNIQUE FLUTE DESIGN for excellent chip evacuation and higher rigidity. Adds stability, aids chip flow and prevents flute clogging in sticky metals.
