M35 steel drill bit with 5% cobalt — engineered for harder alloys and stable cutting performance Key benefits Hardness and durability: Made from M35 steel with 5% cobalt for improved hardness and stability, helping the bit hold its edge under heavy metal drilling. Easier, more accurate drilling: 135° splitpoint geometry reduces the force required to start a hole and keeps the bit centered for a cleaner, more controlled cut. Consistent precision: surface quality on the flutes/vane/wing promotes a clean cutting action and precise hole walls every time. Multipurpose metal performance: Designed to handle stainless steel, cast iron and sheet metal so you can use the same bit across common metalworking tasks. What it does for you Cuts through tough materials with less wear thanks to M35 construction and 5% cobalt reinforcement. Starts quickly and drills straight because of the 135° split point, reducing walking and the need for center punching in many cases. Produces cleaner holes with consistent results because of the quality surface finish on the cutting and flute areas. Primary features Material: M35 speed steel with 5% cobalt for hardness and thermal resistance. Point geometry: 135° split point for reduced entry effort and better centering. Surface quality: Precision ground finish on flutes/vane/wing to support precise cutting action. Suitable applications: Stainless steel, cast iron, sheet metal. Typical use scenarios Workshop repairs and maintenance: Drilling mounting holes through stainless steel brackets or cast iron housings during equipment maintenance. Automotive and mechanical work: Making clean holes in cast components or bodywork sheet metal when fitting parts or modifying assemblies. Metal fabrication and HVAC: Drilling accurate holes in sheet metal for fasteners or ductwork connections. Professional, reliable performance for metalworking tasks where hardness, precise cutting and consistent hole quality matter.
