Tool Kits By CoCud

• Round Rod Size --- Diameter: 20mm / 0.787\"; length: 150mm / 5.9\"; diameter accuracy: +/-0.05mm / 0.002\"; Hardness: HRC61-63
• Wide Applications --- Widely used for machining gravers, drills, turning tools, milling cutters, shafts, punch needles, and center pins. Suitable for the processing of top circle, end face, hole, plane, step and groove on copper, aluminum and non-hardened steel parts.
• Ease of Use --- Steel rods are easy to cut and form replacement parts for almost anything. Smooth surface, easy to form, no crack formation. Can be cut to any size you want.
• High Speed Steel --- The high speed steel tool has high hardness, high strength, good toughness, wear resistance, good for a wide range of applications. Red hardness is the main characteristic of high-speed steel.
• Useful Tips --- Warpage deformation does not affect use. It is not recommended for working environments that require high coaxiality. Reduce contact with air or do not expose to air to prevent rust. Add some anti-rust oil when storing.

• Drill Bit Size Cutting edge diameter: 11.5mm / 0.45\"; shank diameter: 11.5mm / 0.45\"; cutting edge length: 98mm / 3.86\"; overall length: 140mm / 5.5\"; shank type: round shank
• Wide Applications Widely used for drilling stainless steel, aluminum alloy, iron, copper, brass, hard wood, hard plastic, and other metal materials in maintenance departments, machine shops, and other industries. For use on drill presses and bench drills.
• Dual Coatings The dual coatings of gold titanium and black nitride provides better lubricant application, smoother drilling, and is more durable and corrosion resistant than regular black surfaces.
• High Speed Steel The straight shank drill is made of 4341 high-speed steel, with high hardness, good toughness, high strength, and high wear resistance. Sharp spiral flutes provide fast, neat and smooth cuts.
• Useful Tips Choosing the correct lubricant is beneficial for cutting or cooling. Makes cutting easier, improves dimensional accuracy and extends tool life. Check various cutting conditions to ensure proper tool handling.

• Square Tool Bit Size - 5mm x 10mm x 200mm / 0.2\" x 0.39\" x 8\"; Hardness: HRC60-62
• Wide Applications - Suitable for turning, milling, engraving, punching, drilling. Widely used for processing cast iron, A3 ordinary steel, 45 carbon steel, copper, aluminum, die steel, stainless steel, etc.
• Parallel Design - Parallel cutters have a continuous cutting edge width over the entire length of the tool bit.
• High Speed Steel 4241 - High speed steel (HSS) tool bit is with high hardness, good toughness, and wear resistance, good for wide ranges of applications.
• Useful Tips - Used on lathes, milling machines, or metal forming machines. The blanks are necessary for art and craft cutting tools.
