is expanding its milling line with the new CoroMill MF80 for automotive milling applications in ISO K and ISO P materials in close to 90° operations with fixture constraints.

Based on a technology platform similar to the existing CoroMill 345, this new milling tool is said to offer a 40% lighter cutter body with shim protection and a high number of inserts for secure and stable machining, even in vibration-prone overhang applications. The 89.5° approach angle enables the multi-edge cutter to work close to the fixture, which improves machine utilization and is said to ensure a longer tool life with less scrap.

The inserts have eight cutting edges, chip protection and optimized micro geometry for better security and chip evacuation, as well as a wiper edge for a superior surface finish. The cutting edge is inclined for smooth cutting action and low cutting forces, making it ideal for thin-walled components and machine setups with limited stability.

In a roughing shoulder milling performance test with a competing brand, the CoroMill MF80 reportedly showed 67% increase in tool life, boosting overall productivity. The shim protection and high number of insert edges lowered cost per part in this roughing application.
