The 29870 CTD S&D Drill Bit (1-1/32", Type 130-AG) is a heavy-duty reduced-shank (Silver & Deming) twist drill built for tough drilling applications, including work-hardening stainless steels and other hard metals. Made from special Hi-Molybdenum tool steel in a one-piece solid construction, it features a split-point tip for improved starting and reduced walking, plus a gold surface-treated body and clearance to maximize lubricity during drilling.
