• UNIVERSAL 1/4 INCH SHANK – Engineered with a precision-machined 6.35mm (1/4") shank to ensure secure concentricity and minimize vibration at high speeds. These rotary file bits are compatible with most pneumatic air die grinders and electric rotary tools. Note: Please verify your tool's collet size before purchase; not suitable for standard 1/8" rotary models without a proper adapter.
• PREMIUM TUNGSTEN CARBIDE – Constructed from heat-treated tungsten carbide (HRC 70+), these burrs offer superior hardness and wear resistance compared to HSS or high carbon steel files. They retain sharp cutting edges for extended periods, delivering consistent performance on tough materials including hardened steel, stainless steel, cast iron, copper, and aluminum.
• EFFICIENT DOUBLE CUT GEOMETRY – Features a cross-groove tooth design that rapidly removes stock while creating smaller chips for easier cleanup. This double-cut pattern ensures smoother operation with less chatter, preventing the tool from pulling, making it ideal for both heavy material removal and fine surface finishing by DIY enthusiasts and professionals alike.
• VERSATILE SHAPING SOLUTION – This essential kit includes five distinct head shapes: Cylinder, Ball-Nosed Cylinder, Ball, Tree, and Tapered Point. Whether you are chamfering mechanical parts, hollowing out wood for crafts, cleaning up welds, or deburring sharp edges, you have the perfect profile for every contour, angle, and crevice.
• MULTI-PURPOSE CRAFTING TOOL – An indispensable accessory for your workshop, garage, or metalworking station. Perfect for bodywork porting, jewelry making, mold cavity processing, and various DIY arts and crafts. Performs exceptionally well on metal, hardwood, plastic, stone, and bone, significantly reducing manual labor intensity.
