Version: With relief ground knuckle profile. Centre cutting edge geometry for plunging. • Wide, precision ground chip flutes. • Special chip angle for aluminium and non-ferrous metals. Advantage: Suitable for high metal removal rates due to wide chip space. Application: Suitable for: • 138 m/min cutting speed (vc) in aluminium up to 350 N/mm2, long chipping aluminium, thermoplastics and thermoset resins, magnesium alloys, soft copper. • 83 m/min cutting speed (vc) in aluminium cast alloys < 10% Si up to 600 N/mm2, short chipping aluminium, low alloy copper up to 400 N/mm2. • Applicable with emulsion with at least 4 % grease content (for tapping at least 8 %).
