Unmatched Durability & Efficiency: The carbide burrs are made from tungsten carbide, offering high hardness, excellent wear resistance and toughness, and heat and corrosion resistance. Service life is 8 times longer than High-Speed Steel (HSS) tools and 200 times longer than small grinding wheels. Saving you money and time on frequent replacements, and enjoying higher productivity. Advantage for Double-Cut design: Our cross-cut design produces a significantly finer finish than aggressive single-cut burrs. It reduces chip size for smoother cuts, less clean-up, and more control, giving you professional results with minimal effort. Aggressive Yet Controlled Cutting: Experience a high stock removal rate without the struggle. The 1/8 carbide burr bits are well-balanced to reduce vibration and noise, ensuring comfortable, precise control even during long work sessions. The optimized geometry and sharpness allow the tool to do the work, letting you achieve your desired shape or finish faster and with less fatigue.
