For twice the feed rate without compromising the surface quality. Wiper geometry for finishing cuts and medium machining, For twice the feed rate without compromising the surface quality. Finishing to light cutting depths. Good chip clearance Large rake, round cutter shape. Low cutting force and good chip clearance, Wide chip breaker area due to 3D rake angle and double overhang geometry. Extremely stable due to large contact area. First-class sharp cutting edges due to positive rake geometry. Particularly stable cutting edge. Standard chip breaker for smooth to slightly interrupted cutting of cast iron. Polished chip breaker. Very good chip clearance and low tendency to edge build-up. Large rake angle reduces the cutting forces, Lower burr formation due to reduced damage causing formation of notches. For roughing steel. Suitable for heavily interrupted cutting and workpieces with casting skin. Roughing at high feed rates. The chip breaker requires only low cutting force. Positive rake inserts Appli- cation Chip break- er Geometry Characteristics Carbide Finishing 62 Ground all round, sintered geometry for creation of outstanding surface quality, Medium machining -roughing 73 Sintered indexable insert with ideal start geometry for a wide spectrum of materials. Carbide MP-CF Suitable for small depths of cut (0.02 - 0.2 mm). MFP- GF Chip breaker reaches as far as the cutting edge. Sharp cutting edges. Polished insert surface. CTI C MFP- SK Chip breakers for very low cutting forces. Optimised chip breaking for materials steel and stainless steel. v iZ 0.2. 0.2. HQ Chip breaker for medium machining. Radius profile Minor cutting edge profile MQ Radius profile Minor cutting edge profile Good chip clearance when used for internal boring. The chips are small and tightly rolled, so they do not lodge in the toolholder. Constant surface accuracy. GK 0.1 ,, 0.1 i4jr, 17tf Radius profile Minor cutting edge profile Good chip clearance due to chip breaker and chip diverter. :inishing - Tiedium nachining MFP- GQ Cutters with different cutting conditions due to the use of the optimum chip breaker width for the respective cutting depth. Polished surface. AH Sharp cut and good chip clearance, with low cutting force. Low tendency to edge build-up due to polished rake faces. HOLEX Carbide Medium machining PM r Good chip clearance. Medium finishing to medium roughing. MM r High wear resistance due to large rake angle for machining stainless steel. Carbide Medium machining PM MM r Outstanding chip clearance under a very wide range of cutting conditions in steels and also stainless steels.
