Diamond-coated insert grades offer high-performance aluminum drilling

摘要

Sandvik Coromant has unveiled its CoroDrill 880 CVD diamond-coated insert grades, GCN124 and GCN134. The super-hard properties of the diamond coating provide long tool life and combine with innovative chip breaker and geometry designs to guarantee high performance when drilling materials such as aluminum. GCN124 and GCN134 diamond-coated insert grades are designed to offer a low cost per hole in most ISO N materials thanks to long lasting insert tool life. Increased productivity could be gained from elevated cutting data and less machine downtime from fewer insert changes. Further advantages include easy handling in production due to the reliability and long life of the inserts as well as enhanced surface finish inside the hole, which results from the ability to resist BUE and smearing effects.
