82 ISCAR GENERAL PURPOSE DRILLINGExchangeable Drilling HeadsThe IDI %u2026-SG and IDI %u2026-SK exchangeable drill heads have two ducts on the peripheral for providing coolant directly to the cutting zone. The indexable SPADE-CHAMdrill heads are made of IC908 TiAlN PVD nano layer coating grade for prolonged and predictable tool life. The IDI %u2026-SK drill heads have special geometric features for drilling cast iron.The IDI %u2026-SG drill heads are designed for general use and are suitable for machining a large variety of workpiece materials. DCM %u2026-3DIDI %u2026-SKDCM %u2026-5DIDI %u2026-SGDCM %u2026-8DDrill BodyThe CHAM-DRILL drills body were designed and produced with an optimal helix flute angle in terms of hole accuracy, roundness, and straightness. The hole straightness of the CHAM-DRILL drills, under recommended cutting conditions, can be within 0.06 mm.The CHAM-DRILL drills are equipped with internal coolant channels and in combination with the helix flute angle provide effective chip evacuation while maintaining high rigidity.The drills are hard touch coated with a hard (up to 60 HRc) layer to resist wear and corrosion. This improves the flute%u2019s surface finish, reduces friction, and provides excellent chip evacuation. DCM %u2026-3DDCM %u2026-5DDCM %u2026-8D
