Hard alloy burr sets include: SB, SC, SD, SF, SL, and SE-type burrs. Different shapes can meet your needs, such as spherical, cylindrical, oval, tree radius end, flame shape, cylindrical radius end, and cone-shaped radius. Made of heat-treated tungsten carbide YG8, which offers significantly higher wear resistance than high-speed steel. These burrs maintain a sharp cutting edge for extended periods and can withstand high temperatures during use without deformation. Suitable for processing various metal materials, including hardened steel up to HRC70. The double-cut design with a unique tooth angle produces a smoother surface finish due to smaller chip load. End-cutting capability makes them ideal for internal contour work and face milling. High-strength, super-sharp cutting teeth provide better control and efficiently remove material from hard surfaces, saving time and improving productivity. Reduced vibration and smooth cutting action allow for accurate, faster penetration, helping to minimize operator fatigue. Hard alloy burrs are precision tools used for grinding, cutting, deburring, jewelry making, wood carving, mold cleaning, model engineering, cylinder head work, and detailed carving. They are also effective for removing burrs, excess material, sharp edges, and weld seams. Whether you are a beginner, apprentice, or professional, each burr is designed to deliver high precision and efficient performance.
