Exchangeable-Tip Drill for Steel and Cast Iron
The CoroDrill 870 is available from Sandvik Coromant (Fair Lawn, NJ) for both steel and cast iron drilling operations. The CoroDrill 870 is part of a new generation of exchangeable-tip drills and is designed to save time and reduce hole costs.
The 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 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 design, with optimized grade and geometry for steel, ensures hole quality for the intermediate hole-tolerance area of IT9-IT10. CoroDrill 870 saves time and reduces your cost per hole.
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. The drill is available in diameter range: 12 – 25.90 mm (0.472 – 1.020 in) and lengths 3, 5 and 8 × drill diameter as standard. Each drill body has a unique interface size with matching tips to achieve hole tolerances of IT9 – IT10.
