PFERD HSS Twist Drill 3/4" M35 (Co5) INOX 135° Split Point Jobber-Length Premium Cobalt Drill Bits for Tough Materials, Stainless Steel, Non-Ferrous Metals (Pack of 1) - Part 20074

This high-performance M35 cobalt (HSSE-Co5) jobber-length twist drill bit is engineered for demanding industrial and workshop applications that require exceptional durability, accuracy, and heat resistance. Designed with a fully ground, right-hand turning profile and a cross-ground drill tip, this bit offers precise centering, reduced walking, and excellent concentricity for clean, accurate holes every time. Built for superior performance on stainless steel (INOX) and other tough or hard metals, the M35 cobalt composition delivers outstanding temperature resistance and long service life, even under heavy-duty drilling conditions. Its optimized flute geometry ensures very good chip removal, promoting smoother cutting action and improved efficiency across a wide range of materials. Perfect for drilling alloyed steel, high-strength steel, stainless steel, cast materials, and non-ferrous metals, this drill bit is ideal for professionals, tradespeople, and advanced DIY users who need reliable, consistent results. For best performance, follow recommended drilling speeds and use cutting oil or coolant when working with metals (use kerosene on aluminum). When drilling stainless steel, remove surface particles after drilling to help prevent corrosion.
