Yamaloy: CCGX 09T308-ALC Insert Grade K10C CCGX Turning Inserts 80 Rhombic Insert Fits the same Internal/External Toolholders as CCGT Insert Geometry for Finishing & Semi-finishing of Aluminium & Aluminium Alloys Optimised edge and radius geometry. Improved surface finish. Improved chip control. ‘G’ Tolerance for high repeatability. First choice for machining pure aluminium. 30% longer insert life compared to uncoated grade. Insert Grade K10C ISO N05-N15 PVD Coated. Micrograin carbide for machining aluminium and aluminium alloys, 30% higher tool life against uncoated grade. Smooth coating and polished surface gives better chip control. ALC Geometry For finishing & semi finishing of aluminium and aluminium alloys. A unique breaker design gives a sharp cutting edge and positive rake angle. Special edge preparation and surface treatment produce better surface quality and greater chip control, reduced friction and vibration. ‘G’ tolerance inserts for higher repeatability. MPN:
