The new GC4344, GC3334 and GC2334 grades for CoroDrill 870 are produced with Zertivo™, a unique PVD (Physical Vapor Deposition) production technology developed by Sandvik Coromant. Zertivo technology amplifies the grades already exceptional benefits, maintaining the advantageous properties from its predecessors and bringing out significant improvements when it comes to properties such as edge line security, chipping resistance and overall wear resistance.
Johan Ekbäck, Global Product Manager at Sandvik Coromant, says: “Drilling is often carried out late in the manufacturing process with previous operations already having enhanced the initial component’s value. The drilling application, although seemingly simple, is a complex operation that can lead to significant consequences if the tool malfunctions or is run beyond its capacity. That is why, when it comes to wear, our customers want to keep their results predictable and consistent, obtaining a drilling process that can be relied on. Releasing the new CoroDrill 870 grades, our ambition has been to provide customers with increased tool life and reliability in their drilling operations.”
Available in various geometries, the latest grades are highly versatile and cover applications in most ISO materials, although are optimized for ISO P (steel), ISO M (stainless steel) and ISO K (cast iron). All grades are PVD-coated using with Zertivo and designed to deliver specific enhancements related to common wear issues within drilling.
Designed for the intermediate hole-tolerance area of H9–H10, the CoroDrill 870 exchangeable-tip drill saves time and reduces cost-per-hole. The drills can be tailored to best support applications through a selection of diameter, length, step or chamfer possibilities. CoroDrill 870 is available in a diameter range from 10 to 33 mm (0.394 to 1.299 inch) and a depth capacity from 3×D to 12×D.
