The latest edition to Sandvik Coromant’s CoroDrill 860 range has advanced -GM geometry offering high-performance drilling across a wide range of materials and applications, as well as significantly improving tool life.
The launch stems from one of the most popular product ranges from Sandvik Coromant, the R840. Currently, R840 is the largest selling drill in the business’s solid round tools offering. However, new advances in drilling technology, and customers’ needs to improve and better maintain productivity required an upgrade.
CoroDrill 860 with -GM geometry features a new grade and flute design with a multi-layer physical vapor deposition (PVD) coating on the drill tip. Results are improved drilling capabilities across a range of materials and applications and much greater tool life than its predecessor, the R840.
One of the most innovative qualities of the drill is its advanced geometry, with the double margin adding stability, increased core strength, and reinforced corners – all contributing to process security and finished hole quality. The flute is highly polished, which helps improve chip evacuation and reduces heat build-up during the drilling process.
The advanced geometry of the CoroDrill 860-GM makes it ideal for use with a variety of materials – including steel, stainless steel, cast iron, hardened metals – and it performs competitively with non-ferrous metals, such as copper and aluminum, and heat resistant super alloys.
