Specifications: Drill diameter: 3.1 mm / 0.122 in Flute length: 25 mm / 0.98 in Shank diameter: 3.1 mm / 0.122 in Overall length: 43 mm / 1.69 in Material: C2/K20 tungsten carbide Finish: Uncoated Maximum cutting hardness: HRC 45 Package contents: 2 twist drill bits Made of medium-grain C2/K20 tungsten carbide, these drill bits offer good toughness, high hardness (HRA 89), and wear resistance. Their milling and cutting performance supports efficient operation. Carbide tools provide long service life and faster cutting speeds than other substrates. They are widely used for drilling nonferrous metals, cast iron, stainless steel, aluminum, copper, alloy steel, plastic, wood, and other materials. The basic substrate has no additional coating, making the bits suitable for a broad range of applications. The spiral flute design provides fast, clean chip evacuation. The sharp cutting edge delivers smooth, uninterrupted cutting. Suitable lubrication supports cutting or cooling, facilitates cutting, and improves smoothness and dimensional accuracy. Suitable for use on machining centers and CNC lathes. The longer the tool is clamped in the chuck, the better. If the clamping length is shorter, reduce the feed rate and cutting speed to minimize vibration and extend tool life. Select a suitable feed rate and cutting speed based on the material being machined to improve tool life, machining accuracy, and performance.
