The Irwin 15 Piece HSS Cobalt Drill Bit Set is a professional-grade drilling solution designed specifically for working with stainless steel and other high alloys. This comprehensive set delivers the enhanced performance and durability required for demanding metalworking applications. Each drill bit in this set is manufactured from high-quality HSS steel containing 5% cobalt, which significantly improves heat resistance and extends tool life when drilling harder materials.
