CoroDrill 860 With SD Geometry for Secure Short Hole Drilling
A solid carbide drill optimized for drilling in nickel-based heat-resistant super alloy (HRSA) materials, the CoroDrill 860 with -SD geometry offers a consistent and predictable tool life with high hole integrity.
The unique grade, S2BM, combines a fine-grained cemented carbide substrate, a multilayer PVD coating, and a post-treatment, delivering maximum tool life. Additionally, geometry with optimized clearance angles and highly controlled edge preparation, flute shape, corner chamfer, and double margin result in a drill that guarantees high performance.
The refined cutting edges of the CoroDrill 860 help lower cutting forces and improve chip control resulting in an unbeatable combination of penetration rate and precision. The flute shape optimizes chip form to improve chip flow and evacuation.
Design development and testing in multiple HRSA materials have shown that the CoroDrill 860 performs consistently in 3, 5, and 8 x D applications, offering machining stability and process security.
