Carmex Precision Tools Ltd. has announced two notable additions to its line of solid carbide end mills. The CR – Supercut Roughers are specifically designed for high-volume applications that require high metal removal rates in slotting, shouldering, and helical plunging.

The innovative roughing geometry results in smaller chips and low cutting forces, and a reinforced corner chamfer promotes additional strength for longer tool life. Designed for semi-finish profile and center cutting, the multi-flute design is constructed of ultra-fine carbide grade CR3 for high cutting edge stability and wear resistance. The tools also feature a new generation of PVD coating for High Performance Cutting (HPC) applications.

High Performance Cutting (HPC) is also characteristic of the new solid carbide roughers designed for aluminum machining. The optimal flute geometry delivers maximum metal removal rates and better chip evacuation, as well as low cutting forces. The reinforced corner chamfer promotes additional strength for longer tool life. Constructed of ultra-fine carbide grade CA5 for hardness and toughness, the tools are uncoated with a smooth polished surface finish that results in high cutting edge stability and wear resistance.

Jim White, National Sales Manager for Carmex USA, comments, "The new Supercut solid carbide end mills are the latest addition to the Carmex family of milling tools. Incorporating specially formulated carbide grades and, where applicable, the latest in PVD coating technology, they answer customer demands for high metal removal in both hard and abrasive materials and aluminum."
