GBP 57 Chip breaker selection – ISO indexable turning inserts Negative Positive Application Chip breaker Geometry Characteristics Application Chip breaker Geometry Characteristics finishing Finishing with wiper geometry. Suitable for small cutting depths Fine WP For twice the feed rate without MP-CF (0.02 mm − 0.2 mm). compromising the surface quality. Wiper geometry for finish Finishing with wiper geometry. Finishing WQ machining with double the WP For good chip clearance at high feed rate without affecting feed rates. Reduces the Radius profile Minor cutting edge profile the surface quality. surface wear rate. Finishing Stable chip control in a wide feed range Stable chip clearance thanks to PP thanks to 3-stage point structure. MFP-SKS base and chip breaker surfaces. Low cutting force. For finishing from 0.2 mm –1.5 mm. For finishing Stable tool life due to special Finishing – Medium PQ up to light cuts. Good chip clearance. PP cutting edge design with improved strength. Radius profile Minor cutting edge profile Wide chip clearance area Finishing – Medium HQ due to 3D rake angle and double overhang geometry. HQ Chip breaker for medium machining. Radius profile Minor cutting edge profile PS Extremely stable due to large contact area. finishing Sharp cutting edge version Fine Radius profile Minor cutting edge profile MFP-PF for finish machining of materials that are difficult to machine. 0.08 5° 15° Medium PG Chip breaker with stable edges for general machining. Stable chip clearance thanks to base and chip breaker surfaces. MFP-SKS For finishing from 0.2 mm –1.5 mm. Finishing 0.23 0.25 0.08 0.09 For medium machining PMG 20° 7.5° 20.5° 7.5° (wide range of applications). The chip evacuation prevents crater wear Good chip evacuation when used for internal turning. Radius profile Minor cutting edge profile and promotes a long tool life. MQ The swarf is small and tightly rolled so Radius profile Minor cutting edge profile it does not lodge in the toolholder. Roughing For roughing steels. PH Suitable for heavily interrupted cutting Finishing – Medium and workpieces with casting skin. Good chip clearance due to chip breaker GK and chip diverter. Radius profile Minor cutting edge profile machining Roughing at high feed rates. Coarse PX The chip breaker requires only Finishing low cutting force. Good chip clearance. Sharp cutting edge Radius profile Minor cutting edge profile AP for excellent surface quality. Chip breaker polished. Finishing Large rake angle, round cutting edge MQ design. Low cutting force and good chip Sharp cut and good chip clearance Finishing – clearance. Medium Radius profile Minor cutting edge profile AH with low cutting force. Low tendency to edge build-up due to polished rake faces. First-class sharp cutting edges due to Medium MS positive rake geometry. Particularly stable cutting edge. Good chip evacuation when used for Finishing Radius profile Minor cutting edge profile MQ internal turning. The swarf is small and tightly rolled so Radius profile Minor cutting edge profile it does not lodge in the toolholder. Chip breaker with positive Medium KG chisel edge for smooth to interrupted cutting. Polished chip breaker. Medium AH Very good chip clearance and low tendency to edge build-up. Radius profile Minor cutting edge profile Finishing Large rake angle, round cutting edge MQ design. Low cutting force and good chip clearance. Radius profile Minor cutting edge profile Large rake angle reduces the cutting Medium MU forces. Low burr formation due to reduced damage due to formation Radius profile Minor cutting edge profile of notches. machining Highly efficient roughing thanks to Coarse SX unique cutting edge design.
