HELICAL CUTTERS INCREASE MILLING VERSATILITY AND PERFORMANCE

New Mill 1-14? helical cutters from Kennametal (Latrobe, PA) are targeted at "any user that wants to take a greater axial depth-of-cut than can be taken with a standard endmill," says Dennis McNamara, global product manager.

"Users always want to take a greater axial depth-of-cut than the single insert height they are using today," he says. "We now have a solution that will give them what they want — a full range of helical cutters that will allow them the flexibility they require: inserts stacked two, three and four high. The favorite choice is going to be the cutters with inserts stacked two high. Users receive the ability to increase the axial depth-of-cut with little added cost."

Together with the right choice of inserts, Mill 1-14 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. The proprietary Load-Optimized Insert Spacing (LOIS?) technology can further improve the performance of Mill 1-14 cutters by finding the "sweet spot" of insert spacing relative to the torque and horsepower of the machine tool. "With traditional indexable helical end mills, equal insert spacing sometimes causes an uneven load demand on the machine tool," McNamara says. "LOIS technology results in inserts spaced to optimize the positions, minimizing vibrations and reducing uneven power requirements. "Mill 1-14 is a versatile, functional cutter system for a range of cutting tasks," McNamara says. "It's a single tool with multi-functional benefits."
