The CoroDrill 870 exchangeable-tip drill from Sandvik Coromant is designed to reduce costs per hole and save time when drilling in stainless steel, as well as cast iron. The drill can be tailored to optimize applications through diameter range, steps and length possibilities. According to the company, holes can be made more efficiently and closer to the specifications required, leaving them better-suited to subsequent operations. A secure interface between drill body and tip ensures reliability and precision, while a tip-change procedure designed to be quick and easy maximizes active machining time. 

New cutting edge geometries and grades are said to provide a safe cutting process, enabling increased penetration rates, while maintaining chip control and increasing tool life. Grade GC2234 includes a fine-grained, high-chromium substrate and a PVD coating with optimized composition for ISO M drilling (stainless). The thin AlTiN PVD coating includes enhanced adhesion steps designed for longer tool life and increased chipping resistance.

The CoroDrill 870 is available in diameters ranging from 10 to 26.65 mm (0.394" to 1.049") and lengths of as much as 8× drill diameter. Each drill body has a unique interface size with matching tips to achieve hole tolerances of H9–H10.
