GoldEdge cyrogenic drill bits and cutting tools are designed to perform against hard materials in the most demanding conditions. Cryogenic drill bits from GoldEdge are manufactured for use with work-hardening grades of stainless steel and other difficult to drill materials. The patented cryogenic treatment process changes the structure of the steel of the cryogenically treated bits and tools. The result is a significant increase in the cutting life as compared to even the highest quality high speed steel drill bits. GoldEdge drills can reduce your cost-per-hole due to its extended life and cutting performance.
