Kennametal introduces anti-rotation design Rodeka indexable inserts

Kennametal's three variable Rodeka topography styles combined with robust cutting edges are designed to help achieve low cutting forces and consume less power. The –LD style inserts have a honed edge for light to medium machining and are indicated particularly for stainless steel and titanium; –GD inserts, intended for medium to heavy machining, have a 10º positive T-land and hone; and –HD inserts have a 0º T-land and hone for heaving machine tasks and cast irons. Each insert is marked so that it is easy to identify the insert topography and edge number for correct indexing in the tool pocket. For correct indexing, the dimple in the edge of each number must be aligned with the groove in the cutter. Inserts should be rotated counter-clockwise to keep a fresh cutting edge and maintain performance. Although an insufficient negative clearance angle limits the ramping capabilities of Rodeka inserts, they are capable of pocketing, profiling, face milling and blade machining at high metal removal rates with long tool life, says Kennametal. Rodeka is available in a range of cutter styles and diameters. These include a 32 to 42 mm diameter screw-on option, a 32 mm diameter Weldon style, 32 mm cylindrical shank end mill and shell mill cutters from 40 to 100 mm diameter.
