Document √FEATURE:M35 high-speed steel drill bits, containing 4.50% to 5.50% cobalt, has high hardness. These bits are recognized for their exceptional wear resistance, impressive heat resistance, and high crack resistance, making them suitable for machining high-hardness metals.Gold Finish can be used to improve the surface properties of drill bits' materials and increase their wear resistance and corrosion resistance, thus extending the service life of the drill bit.and working efficiencyThe 135-degree split point tip 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 metal, 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: 5/16"(7.94mm)-Shank Diameter: 5/16"-Flute Length: 80mm/3.15inch -Total Length: 115mm/4.53inch-Package Content: 12pcs x Drill Bit√NOTE:Applicable coolant, during the machining process, friction between the drill bit and the material generates a significant amount of heat, coolant can effectively reduce the temperature, preventing the tool from overheating, and extending the drill bit lifespan. 5/16" Drill Bit Straight Shank M35 5% Cobalt HSS for Metal Steel - 12 Pack √FEATURE: M35 high-speed steel drill bits, containing 4.50% to 5.50% cobalt, has high hardness.

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.
