The drill is designed as a one-shot solution and the point geometry can be designed to enter in machined surfaces as well as pre-casted bores. Internal coolant channel design for improved chip evacuation. › BENEFIT A high performance one-shot solution, reduced overall cycle time, less tool changes, fewer tools in operation. Maintaining IT9 tolerances up to 10 x d. › CUTTING DATA EXAMPLE n = 10000 RPM, fn = 0.4-0.5 mm/rev. › FEATURES Step drill with the unique point geometry called “Twin Point”. Drills in full material with interrupted cuts. Specially designed internal coolant channels ensure optimum chip flow. › BENEFIT Lowest possible machining time due to one-shot process. Very good tool life and process reliability. › CUTTING DATA EXAMPLE n = 6000 RPM, fn = 0.35 mm/rev. 4
