01V025 - Walter SM-42 Double Cut Tungsten Carbide Rotary File

Precision Engineering for Industrial Material Removal

The Walter 01V025 Carbide Burr SM-42 DC represents the pinnacle of rotary file technology, designed specifically for industrial environments where precision and efficiency are paramount. Crafted from the finest grade of tungsten carbide, this tool is engineered to withstand the high thermal and mechanical stresses associated with heavy-duty grinding and deburring operations. The manufacturing process employed by Walter ensures impeccable concentricity, a critical factor that minimizes runout and vibration. This balance not only extends the life of the burr itself but also protects the bearings of your pneumatic or electric die grinder, ensuring a smoother operation and reduced operator fatigue over long shifts.

The defining feature of this SM-42 burr is its "alternate diamond pattern," commonly referred to in the industry as a Double Cut. Unlike single-cut fluting, which produces long, stringy chips and can be difficult to control, the double-cut geometry breaks material down into small, manageable granular chips. This design significantly enhances operator control, allowing for aggressive material removal rates without sacrificing surface finish quality. It is particularly effective on ferrous metals, including mild steel and stainless steel, where maintaining a consistent cut without loading is essential.

Applications for the SM-42 shape are diverse, ranging from enlarging holes and slots to intricate fine finishing work in confined spaces. The conical profile allows access to angled geometries that cylindrical burrs cannot reach. Whether used for preparing weld seams, deburring machined parts, or contouring molds, the Walter Carbide Burr delivers consistent performance. Its exceptional longevity means fewer tool changes and lower overall consumable costs, making it a smart investment for fabrication shops focused on productivity and quality assurance.
