3/8 in Ball Shape Carbide Burr, 6-3/8 in Long Double Cut, 1/4 in Shank
Product Details
The MASTERCUT SD-3L6DC is an SD-style ball shape carbide burr with a 3/8 in cutting diameter and 6-3/8 in overall length, purpose-built for contractors who need extended reach in deep cavities and hard-to-access areas. The double-cut tooth pattern delivers fast, efficient material removal with reduced vibration across a wide range of metals including steel, stainless steel, cast iron, and titanium. Ball geometry enables precise contouring, blending, and material removal in concave sections and complex geometries that straight-profile burrs cannot reach. Manufactured in the USA from A-Gr-SiV Premium Carbide Blend, this burr is engineered for exceptional toughness and long tool life in production environments. It is ideal for deburring, weld cleanup, porting, engraving, and 3D surface profiling applications.
- SD Ball shape geometry enables controlled material removal in concave areas, internal surfaces, and complex 3D workpiece profiles
- Double-cut tooth pattern provides fast stock removal with reduced vibration and chatter for a smoother finish
- Long 6-3/8 in overall length delivers extended reach for deep cavities and hard-to-access areas inaccessible by standard-length burrs
- Manufactured from A-Gr-SiV Premium Carbide Blend for excellent toughness and extended tool life under demanding conditions
- 1/4 in shank diameter for compatibility with standard die grinders and rotary tools
- Suited for steel, stainless steel, cast iron, hardened materials, superalloys, and titanium
- Made in the USA from solid carbide for consistent, high-performance results across production applications
- Recommended operating speed of 25,000-30,000 RPM for the 3/8 in cutting diameter
