SANDVIK Coromant has released a solid carbide drill with increased accuracy, extended tool life and improved productivity for heat resistant alloy (HRSA) machining. According to the company, the CoroDrill Delta-C R846 has a positive-tip geometry that maintains a more consistent curve along the cutting edge. This distributes cutting forces throughout the body for longer tool life and minimum deflection and burr formation.A bronze physical vapour deposition coating makes the tool wear-resistant by protecting the substrate.The tool has added strength on the outer diameter corners, where cutting forces are strongest in demanding applications. A deeper flute design on the body of the Delta-C is said to optimise chip removal.This allows the tool to operate free from obstruction to retain the closest possible tolerance and produce high surface finishes.The Delta-C is expected to find applications in industries where work with HRSA is required, such as the aerospace and industrial gas turbine sectors.Key contact:Kari Parventokari.parvento@sandvik.com
