Advantages
Extreme Roughing
First choice for maximum metal removal rates in low carbon steels alloy steels pre-hardened steel (up to HRC45) and cast iron
Silent Machining
Strong core and special cutter geometry reduce harmonics and eliminate vibration
Ultimate Tool Life
Premium micrograin carbide substrate combined with X1100 coating improves performance
Cost Efficient
Large depths of cut plus high feed rates reduce cycle times
Features
Special Pitch
Variable pitch reduces vibration and cutting forces allowing large depths of cut and high feed rates
Swarf Control
Special uneven ripper tooth design breaks swarf down improving chip flow
Strong Cutting Edge
Corner radius geometry strengthens cutting edges reducing risk of premature failure
Versatile Performance
Excels in slotting, shouldering, plunge and pocket milling due to strong tooth end design
Double Core Geometry
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.
