Professional-grade product with a wide range of uses: M35 high-speed steel drill bits with 5% cobalt for drilling stainless steel and reinforced steel. They can also be used to drill metals and other materials, such as cast iron, copper, high-temperature alloys, titanium alloys, aluminum, plastics, and hardwoods, etc.

Superior quality materials: M35 high-speed steel with 5% cobalt. Durable and robust for a longer service life. Drill bits suitable for drilling tough metals, including stainless steels, Cr-Ni, and special acid-resistant steels.

Heat Resistant: High-speed steel twist drills with cobalt should be used at 1500 rpm or more for maximum efficiency. The straight shank allows for a firm and precise hold, compatible with standard chucks and regular round collets.

Twisted Design and Performance: Precise 135° split point, origami oxide finish, straight round teeth. Prevents chipping, removes chips and particles faster. Product fully precision ground, ensuring the scope moves easily.

Easy Storage and Use: Set of 10 M35 steel twist drill bits with cobalt coating - Drill bit diameter: 3.5mm - Flute length: 39mm - Total length: 70mm. Set of 10 pieces packaged in a plastic box for easy use and storage.
