Mill 1-14 helical cutters from Kennametal are targeted at any customer that wants to take an axial depth of cut than what can be taken with a standard end mill. The company now has a full range of helical cutters that will allow them the flexibility they require, inserts stacked two, three and four high.
Together, with the right choice of inserts, these helical cutters can be used for medium to heavy roughing and semi-finishing in such applications as contour profiling, slotting, ramping, helical ramping from solid and plunge milling. The company’s Load-Optimized Insert Spacing (LOIS) technology can further improve the performance of the cutters by finding the “sweet spot” of insert spacing relative to the torque and horsepower of the machine tool.
LOIS technology results in inserts spaced to optimize the positions, minimizing vibrations and reducing uneven power requirements, according to the company.
Axial support pins on the Mill 1-14 give additional insert stability when ramping or plunging, improving surface finishes. As many as nine different coolant nozzle sizes are possible for consistent, focused coolant flow.
