Roughing End Mill Enables High Feed Rates in Aluminum

Inovatools’ Primus HPC aluminum roughing end mill features a special entwined tooth system and optimized microgeometry. The tool, designed for inner cooling and multi-turning, enables high feed rates with quiet, low-vibration operation and low power consumption, according to the company. A special entwined profile with optimized chip control and a high-performance TaC coating eliminate the usual problems in cutting aluminum, such as adhesion tendency with built-up edges, welding deposits, chip caking and burr formation.

The TaC coating, combined with cutting edge preparation, makes this tool resilient and prevents micro-chipping. The entwined profile’s chip separators also contributes to longer tool life. These break the aluminum chips quickly, while the large chip grooves rapidly transport them away from the intervention zone with KSS. Not only does this promote process security, but it also ensures low-vibration running for high surface quality, even during HPC roughing.

The three-edged Primus is available in diameter ranges from 6 to 20 mm with inner cooling, multi-turning and HB shank design.
