Exchangeable-Tip Drill Now Available for Stainless Steel
Drilling in stainless steel sees reduced costs per hole and time savings with the CoroDrill 870 from Sandvik Cormant (Fair Lawn, NJ). The CoroDrill 870 is part of a new generation of exchangeable-tip drills for steel and cast iron drilling.
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 maximizes active machining time.
The exchangeable tip drill CoroDrill 870 is a high-tech development in which the drill tip, interface and drill body have been individually optimized and then combined.
The new cutting edge geometries and grades provide a safe cutting process, allowing for increased penetration rates while maintaining chip control and increasing tool life. Grade GC2234 includes a fine-grained high chromium substrate and a new PVD coating with optimized composition for ISO M drilling (stainless). The thin AlTiN PVD coating includes enhanced adhesion steps resulting in longer tool life and increased chipping resistance.
The drill is available in diameter range10.00 mm through 26.65 mm (0.394 in through 1.049 in) and lengths up to 8X drill diameter as standard. Each drill body has a unique interface size with matching tips to achieve hole tolerances of H9 through H10.
