Description
Document 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.√APPLICATIONThe M42 HSS titanium coated twist drill is engineered for high-hardness, high-viscosity, and high-temperature materials due to its exceptional red hardness, wear resistance, and anti-adhesion properties. It is suitable for drilling: High-temperature alloys, Titanium alloys, Stainless steel, Hardened steel, Cast iron, Hard plastics, and Wood√PACKING LIST:-Flute Diameter: 10.5mm/0.41 inch ≈ 13/32inch-Shank Diameter: 10.5mm-Flute Length: 87mm/3.43 inch-Total Length: 133mm/5.24 inch-Package Content: 4pcs x Drill Bit√NOTE:During the machining process, friction between the drill bit and the material generates significant heat. Using coolant effectively reduces the temperature, preventing tool overheating and extending the lifespan of the drill bits. 10.5mm Drill Bit M42 8% Cobalt HSS 135° for Hard Metal - 4 Pack M42 8% Cobalt high-speed steel is formulated with a high cobalt and molybdenum-vanadium alloy, offering superior toughness, hardness, and wear resistance.

The item was as described and good quality. It was a little more expensive than I would have expected but in keeping with other, similar offers. I have one important complaint, the person who delivered the package “ threw” it over my fence, onto the lawn. It was delivered to my door, or put in my post box, through the pedestrian gate. Fortunately you packed it well, so it didn’t break. Maybe for this type of item it should be labelled fragile, although I doubt this deliverer would have cared.
Great Seller, have no hesitation in giving a recommendation, went out of his way to give me a great deal on this high-quality blade. Was unable to obtain this blade with a 15.88mm bore in Australia, The Item was well packed for its journey from China, and arrived in the time frame that the seller advised My thanks for making this a fantastic buying experience. Arrived 11/11/2025 Armistice Day
Adequate packaging, fast delivery by post (9 days to a rural location), exactly as described, reasonable value for money. Looking around, it seems these particular patch cables are fairly limited, so I was happy to pay the price for them - buying standard patch cords and plug adapters would probably cost more! Good communications and fast response from seller - I recommend them.
