Carbide Drill for Nickel-Based HRSA Components

Sandvik Coromant offers a solid carbide drill optimized for drilling in nickel-based heat-resistant super alloy (HRSA) materials, with a standard drilling depth capability of up to 8 x D.

"The CoroDrill 860 with -SD geometry offers a consistent and predictable tool life with high hole integrity, which is of the utmost importance in industries with extremely high demands and processes in place to safeguard quality, such as the aerospace industry," said a company spokesperson.

The spokesperson continued, "Current strategies for drilling nickel-alloy aircraft engine parts, where process security is paramount, cannot meet high demands from the industry and do not offer a maximum tool life. That is where the new CoroDrill 860 with -SD geometry, which is purpose-designed for machining of nickel alloys, comes in."

There are several key features that contribute to the high performance for HRSA materials. First is the grade-S2BM-which combines a fine-grained cemented carbide substrate, a multilayer PVD coating and a post-treatment for longer 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 the highest performance and process security," said the spokesperson.

The spokesperson added: "Extensive design development and comprehensive product tests in multiple HRSA materials have shown that the CoroDrill 860 with -SD geometry performs consistently in 3, 5 and 8 x 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."
