KangTeer Tungsten Carbide Burr Set 4pcs, 1/4" Shank 12mm Single Cut Rotary Files Professional Die Grinder Bits for Metal, Ideal for Deburring Steel, Iron, Copper & Aluminium

COMPLETE 4-PIECE VALUE SET: This practical bundle includes 4 essential burr shapes (e.g., Tree, Cylinder, Ball, Oval) to tackle a wide range of tasks. It offers great value, eliminating the need to purchase shapes individually and equipping you for various deburring, carving, and grinding applications. SINGLE CUT FOR SMOOTH FINISHES ON HARD MATERIALS: The single-cut (straight flute) design is specifically engineered for hard metals like stainless steel, cast iron, and hardened steel. It produces long, controllable chips and a noticeably smoother surface finish compared to double-cut burrs, with reduced grabbing and tearing. TUNGSTEN CARBIDE CONSTRUCTION: Forged from premium tungsten carbide, these burrs are significantly harder and more wear-resistant than standard high-speed steel (HSS) bits. They withstand high temperatures and maintain a sharp cutting edge longer, ensuring superior performance and extended tool life under demanding conditions. ERSATILE SHAPES FOR PRECISION WORK: Each shape serves a unique purpose. The tree shape reaches into tight corners, the cylinder shapes flat surfaces and slots, the ball shape for contours, and the oval shape for curved edges. This combination allows for detailed and precise work on iron, copper, aluminium, and other metals. UNIVERSAL 1/4" SHANK FOR WIDE COMPATIBILITY: Features a standard 1/4-inch (6.35mm) shank that securely fits all common die grinders, electric drills, and pneumatic rotary tools. This ensures easy integration into your existing workshop setup, making it a go-to tool for professionals and serious DIY enthusiasts in metalworking and fabrication.
