New generation of exchangeable-tip drills

Available for both steel and cast-iron drilling operations, the CoroDrill 870 from Sandvik Coromant (www.sandvik.coromant.com) is part of a new generation of exchangeable-tip drills designed to save production time and reduce hole costs. CoroDrill 870 can be tailored to optimise applications via a range of diameters and lengths. A highly secure interface between the drill body and tip ensures reliability and precision, while the quick-and-easy tip change procedure helps to maximise active machining time.

Moreover, new cutting-edge geometries and grades are said to ensure a safe cutting process, allowing for increased penetration rates while maintaining chip control and increasing tool life. The drill is available in the diameter range 12–25.90mm, and in lengths of 3, 5 and 8 ¥ drill diameter as standard. Each drill body also has a unique interface size with matching tips to achieve hole tolerances of IT9–IT10.
