Walter Surface Technologies 01V646 Carbide Bur SG3

Product Description

The WALTER SURFACE TECHNOLOGIES 01V646 is a double-cut carbide abrasive bur designed for aggressive material removal in metalworking and fabrication applications. Built to the SG-3 industry specification, this taper-style bur features a tree with pointed end head shape and a 3/8 inch cutting diameter. The 1/4 inch shank fits standard die grinders and rotary tools, and the uncoated carbide head runs at up to 33,000 RPM. With an overall length of 6.75 inches and a 3/4 inch length of cut, it delivers controlled stock removal in tight or contoured workspaces. Machinists, fabricators, and weld prep technicians are the primary users.

This bur is suited for use on steel, stainless steel, cast iron, superalloys, and titanium. It handles weld bead blending, port work, deburring, and surface contouring in both shop and field environments. The double-cut tooth pattern produces a smoother finish than single-cut designs while still removing material efficiently. It is well matched to maintenance and repair operations as well as production metalworking where precise, consistent burring is required.
