Durable M35 steel construction with 5% cobalt for improved hardness and stability — built to withstand heat and maintain edge life under heavy use. 135° split point tip reduces bit walking and requires less downward force, so you start holes accurately and drill through stainless steel and other hard materials with less effort. Precisionshaped vane/wing geometry and a quality surface finish deliver clean, consistent cuts and longer tool life. Multipurpose performance: designed for stainless steel, cast iron, and sheet metal — one bit covers common metalworking needs. What you get and why it matters Longlasting cutting power: M35 steel plus 5% cobalt increases wear resistance and heat tolerance, so bits stay sharp longer and tolerate tougher drilling tasks. Faster, more accurate starts: the 135° split point bites immediately and minimizes walking, reducing the need for center punching in many applications. Cleaner holes, less rework: the surface quality and vane/wing design evacuate chips efficiently and produce precise, repeatable holes. Typical uses Metal fabrication: drilling mounting holes and fastener locations in stainless steel panels and brackets. Automotive and machinery : making or enlarging holes in cast iron parts and steel components. HVAC, electrical, and sheet metal work: cutting clean holes through thin to mediumgauge sheet metal for ducts, enclosures, and panels. Compatibility and performance notes suited for stainless steel, cast iron, and sheet metal; performs well on other ferrous and nonferrous metals. Designed to reduce heat buildup and bit wear during demanding metaldrilling tasks. Choose these M35 bits when you need consistent, accurate holes in metalwork and a durable tool that maintains performance under repeated use.
