CTD S&D Drill Bit, 1-1/2" Type 130-AG

The 29980 CTD S&D Drill Bit, 1-1/2" Type 130-AG is a heavy-duty reduced shank (Silver & Deming) twist drill made from high speed steel and designed for demanding drilling, including work-hardening stainless steels and other hard metals. Built with one-piece solid construction and special Hi-Molybdenum tool steel, it features a split point geometry for improved starting and reduced walking, plus a gold surface-treated body and clearance to maximize lubricity and help manage heat in tough materials.
