M35 Cobalt Twist Drill Bits for Metal, Wood, and Plastic — engineered for high performance in metalworking and beyond.
These high-speed steel drill bits are made with a premium M35 cobalt alloy, delivering exceptional hardness, strength, heat resistance, and wear resistance for long-lasting performance. The cobalt addition boosts heat tolerance, helping the bit maintain a sharp edge and efficient cutting even during prolonged use.
-
Superior cutting materials: M35 cobalt alloy provides excellent durability for drilling through hard metals, stainless steel, cast iron, and other tough materials.
-
Balanced and reliable: Straight shank design ensures compatibility with standard drill chucks and stable, true holes.
-
Precise results: Sharp cutting edges produce clean, accurately sized holes with reduced burrs.
-
Versatile applications: Suitable for drilling in metal, wood, and plastic when used with appropriate speeds and lubrication.
Usage notes: Use the correct drill speed setting—harder materials require slower speeds to prevent overheating and bit damage. Apply lubricant, such as cutting oil or coolant, when drilling metal to reduce friction and prolong bit life.
Origin: Mainland China. Ideal for industrial applications, fabrication, and DIY projects that demand reliable, long-lasting drilling performance.
