Solid carbide spiral drill, 3 x D
Design: solid carbide, DIN 6537 K, type H. TiAIN coated surface, right cutting with 4 surface point. Convex flutes give the tool extremely high stability and ensure the optimum chip breaking. The slot profile adapted to suit hard machining safely transports the chips out of the hole. Carbide application group: K/P –universal use. (Ultra-finest grain K05–K50/P05–P50) Application: Suitable for holes in annealed steels up to 62 HRC. Note: The drills can be sharpened and recoated several times.
Design: solid carbide, DIN 6537 K, type RT 100 VA. TiAIN coated surface, right cutting with special point geometry and cross point thinning. Normal angle of rake, normal core thickness and without core gradient. The drill has a very good self-centring behaviour and produces short chips. Application: For accurate alignment drilling with narrow ∅ tolerances and good surfaces. Suitable for drilling holes up to 4 x D with high cutting values. Particularly suitable for cutting stainless steels. Note: The drills can be sharpened and recoated several times.
