SuperV-drills without internal coolant Ø 4.200

High-performance drill for drilling into long and short-chipping materials such as structural and case hardened steels, cast steels, heat-treatable steels and alloyed steels with a tensile strength of up to 1200 N/mm² including carbon steels, cast iron and high-alloyed AlSi-alloys. Multi-purpose application (TiAlN nano-coating) in small batch production, where one tool is used for drilling several different materials. Advantages: Highest speed and feed rates possible (see application recommendations). High alignment accuracy with small diameter tolerance and excellent surface finish. Excellent self centring qualities as well as producing short chips. Pre-conditions for use: powerful machines. No play in spindlebearings. Accurately aligned toolholders. Max. concentricity error of clamped tools: 0.02 mm. Chatterfree, mechanical feeds.
