Sandvik Coromant Introduces CoroDrill® 860 with -SD Geometry for Machining in HRSA Materials

Sandviken, Sweden – Sandvik Coromant, a global metal cutting leader, introduces a new solid carbide drill optimized for drilling in nickel-based HRSA materials, with a standard drilling depth capability of up to 8×D. CoroDrill® 860 with -SD geometry offers consistent and predictable tool life with high hole integrity, which is of utmost importance in industries with extremely high demands and processes in place to safeguard quality—such as the aerospace industry.

Current strategies for drilling nickel-alloy aero-engine parts, where process security is paramount, cannot meet the high demands from the industry and do not achieve maximum tool life. The new CoroDrill® 860 with -SD geometry, which is purpose-designed for superior machining of nickel alloys, does. Robert Smith, Offer Manager - Hole Making and Composites, Sandvik Coromant, says, “CoroDrill® 860 with -SD geometry is a reliable drill that guarantees the highest performance and process security in heat resistant super alloys.”

There are several key features that in combination contribute to the high level of performance in HRSA materials. Starting with the unique grade, S2BM, that combines a fine-grained cemented carbide substrate, a multi-layer PVD coating and post treatment delivering maximum tool life. Adding on a geometry with optimized clearance angles, highly controlled edge preparation, flute shape, corner chamfer, and double margin—the result is a drill that guarantees the highest performance and process security.

Extensive design development and comprehensive product tests in multiple HRSA materials have shown that CoroDrill® 860 with -SD geometry has consistent performance in 3, 5, and 8 × D applications, offering excellent machining stability and process security. This makes process planning and cost calculations more reliable when predicting tool life and conducting cost-per-part analysis. “Customers can be confident the CoroDrill® 860 with -SD geometry is a reliable drill that guarantees the highest performance and process security, delivering the highest tool life therefore reducing cost per hole and component.” adds Smith. “CoroDrill® 860 with -SD geometry is the drill to trust for high-value components.”
