Mill 1-14 helical cutters from Kennametal are designed for greater axial depth of cut than a standard end mill, the company says. The flexible cutter range features inserts stacked two, three and four high.
The helical cutters can be used for medium to heavy roughing and semi-finishing in applications such as contour profiling, slotting, ramping, helical ramping from solid and plunge milling. Load-optimized insert spacing (LOIS) technology can further improve cutter performance by finding the “sweet spot” of insert spacing relative to the torque and horsepower of the machine tool, the company says. This minimizes vibrations and reduces uneven power requirements.
Axial support pins on the helical cutters give additional insert stability when ramping or plunging for improved surface finishes. As many as nine different coolant nozzle sizes are available for consistent, focused coolant flow.
