Exchangeable-Tip Drill for Stainless Steel
April 1, 2014
"Drilling in stainless steel can be performed at reduced costs per hole and with time savings with the CoroDrill 870. The CoroDrill 870 is part of a new generation of exchangeable-tip drills and was recently launched by Sandvik for steel and cast iron drilling," said a spokesperson.
CoroDrill 870 can be tailored for 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," said a spokesperson.
The new cutting edge geometries and grades are designed for a safe cutting process, allowing for increased penetration rates while maintaining chip control. 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.
The drill is available in diameter range: 10.00-26.65 mm (0.394-1.049 inch) and lengths up to 8 x drill diameter as standard. Each drill body has a unique interface size with matching tips to achieve hole tolerances of H9-H10.
