M42 8% Cobalt high-speed steel is formulated with a high cobalt and molybdenum-vanadium alloy, offering superior toughness, hardness, and wear resistance. It optimally balances high-temperature hardness, wear resistance, and durability.Titanium Nitride (TiN) Coated: Enhances twist drill performance by increasing hardness, reducing friction, improving oxidation resistance, and preventing material adhesion. This coating significantly improves drill bits' lifespan, machining efficiency135-degree split point tip design:The drill bit's 135-degree angle enhances stability and precision when drilling hard materials. This design improves heat dissipation and tool durability, making it suitable for hardened steel, cast iron, and other tough alloys.

1. The M35 drill bit is made of cobalt high speed steel, contain 5% Cobalt, high hardness, fast cutting speed, improve wear resistance, more durable than ordinary high speed steel drill bit.2. The cobalt drill bit can be used to harden materials. Such as hard metal, stainless steel, copper, aluminum, cast iron, plastic and wood, can also be used for softer materials. Not suitable for glass or ceramic materials.3. 135° Quick-cut split point, round straight shank, prevent walking, make drilling accurate and faster. Fully ground spiral groove design, quickly removes debris, reduces friction and heat, ensures smooth chip movement.4. This series are small drill bits, please note the size before you buy. Suggest speed 100-800r/min.

D uses M35 high-speed steel material and fully ground drill bits;. Double helix chip groove. The optimal rotation speed of the electric drill should be between 80-120. The faster the rotation speed, the more difficult it is to drill, which can burn out the drill bit and cause annealing.
