Kyocera Precision Tools Inc. says positive-style inserts with its WP chipbreaker and a wiper cutting edge impart fine surface finishes at low cutting forces. The chipbreaker stabilizes chip conditions at low feed rates, controls excess chip breaking during high-feed and high-load machining and prevents tearing of the finished surface by controlling adhesion. The inserts are for machining steel and stainless steel and are available in a variety of CVD- and PVD-coated grades.

- chipbreaker
chipbreaker
Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to control, catch in turning parts and cause safety problems.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- wiper
wiper
Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
