Carmex Helix solid tungsten carbide milling cutter with three cutting edges for roughing aluminium alloys are innovative high performance (HPC) milling cutters designed specifically for aluminium machining. Thanks to the passage of coolant inside the grooves between the cutting edges, it facilitates the roughing work of the cutter by significantly improving chip evacuation, especially in blind holes.
The special geometry, the sharpening, the coolant passage, the reinforced corner chamfer, and the finish of the cutting edge recess, guarantee the user high cutting speeds and a high feed rate for chip removal. thus contributing to an increase in the life and performance of the cutter.

Carbide grade CA5: An ultra-fine carbide grade with high hardness and toughness, providing high cutting edge stability and wear resistance.
