STAFFORD, Staffordshire, UK and FAIR LAWN, N.J.—Sandvik Coromant has launched the latest edition to its CoroDrill® 860 range. The CoroDrill 860 has an advanced -GM geometry that offers high-performance drilling across a wide range of materials and applications, as well as significantly improved tool life, the company said in a release.

The new launch stems from one of the most popular product ranges from Sandvik Coromant, the R840. Currently, the 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 their productivity, meant that it was time for an upgrade.

The CoroDrill 860 offers a new grade, innovative flute design with a multi-layer physical vapor deposition (PVD) coating on the drill tip. The results are improved drilling capabilities across a range of materials and applications — including general engineering and automotive — and a much greater tool life than its predecessor, the R840, according to the release.

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 of which contribute 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 suitable for use with a variety of materials — including steel, stainless steel, cast iron, and hardened metals. It also performs competitively with non-ferrous metals, such as copper and aluminum, and heat-resistant super alloys.

“Sandvik Coromant provides machining solutions for a multitude of industrial sectors,” said James Thorpe, global product manager at Sandvik Coromant, in the release. “We are always improving our offering and understand that enhanced tool life and improved productivity are two of our customers’ major requirements. The CoroDrill 860 with -GM geometry is suitable for applications where hole quality is critical within the automotive, general machinery, and oil and gas industries.

“We wanted to offer an improved solution for a vast range of industrial applications, and also to streamline our product offering,” said Thorpe. “We’ve achieved this with a single, multi-purpose drill that gives superior performance across a range of materials.”
