√FEATURE:M35 drill bit is a cobalt-containing high-speed steel (5% cobalt), offering excellent heat resistance and wear resistance. It is well-suited for machining high-hardness materials such as stainless steel and alloy steel. The cobalt content enhances cutting stability at high temperatures, reducing the risk of edge chipping—making it particularly suitable for high-speed or interrupted cutting conditions.Shank (4241 High-Speed Steel)4241 is a standard high-speed steel with lower hardness but better toughness and bending strength. Its low cost makes it suitable for non-cutting structural support. This design reduces overall manufacturing costs while ensuring sufficient torsional strength for secure clamping, preventing breakage.Cobalt Drill bit with Titanium Aluminum Nitride (TiAlN) Coating — Engineered with 5% cobalt and a professional-grade TiAlN coating, our drill bits offer exceptional oxidation resistance while dramatically enhancing hardness and durability for superior performance in demanding applications.The 135-degree split point drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.√APPLICATION:The 5% cobalt high-speed steel drill bits are specifically designed for cutting hard metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.√PACKING LIST:-Cutting Edge Diameter: 5/8" (15.875mm)-Shank Diameter: 1/2" (12.7mm);-Flute Length: 80mm/3.15 inch-Total Length: 152.4mm/6 inch-Package Content: 1 x Cobal Drill Bit
