The CoroDrill 870, for the intermediate hole-tolerance area of IT9–IT10, is designed to save time and reduce hole costs. CoroDrill 870 can be tailored to optimize applications through diameter range, steps and length possibilities. Holes can be made more efficiently and closer to the specifications required, leaving them better suited to subsequent operations. A highly secure interface between drill body and tip ensures reliability and precision, while the quick and easy tip change procedure helps to maximize active machining time.
The new cutting edge geometry provides a safe cutting process with optimized chip control, high penetration rates and long dependable tool life. The drill is available in diameter range: 12–20.99 mm (0.472–0.826 inch) and lengths 3 and 5 × hole diameter as standard.
