01V022 - Walter SF-42 Double Cut Tungsten Carbide Burr 1/8-Inch Shank

Precision Grinding with Walter Tungsten Carbide Burrs

The Walter 01V022 Carbide Burr (Model SF-42 DC) represents the pinnacle of rotary file technology for industrial maintenance, repair, and operations. Engineered from the finest grade of tungsten carbide, this tool is designed to withstand the rigorous demands of heavy-duty metal removal while maintaining a sharp cutting edge far longer than standard high-speed steel alternatives. The manufacturing process employed by Walter ensures flawless concentricity between the head and the shank. This precision balance is critical in high-RPM applications, as it significantly reduces vibration, preventing chatter marks on the workpiece and reducing wear on your pneumatic or electric die grinder bearings.

This specific model features a Double Cut (DC) geometry. Unlike single cut burrs that produce long, stringy chips, the double cut pattern incorporates cross-cut flutes that break chips into small, manageable granular particles. This design not only prevents loading of the flutes but also allows for more aggressive stock removal while simultaneously leaving a smoother surface finish. The SF-42 shape—a tree with a radius end—is particularly versatile, making it an excellent choice for contouring, enlarging holes, and working in confined concave surfaces where a pointed or flat end would be unsuitable.

Ideal for MRO professionals working with stainless steel and mild steel, the Walter 01V022 ensures efficiency and safety. Its 1/8-inch shank fits standard collets, providing a secure grip for precision work. Whether you are deburring machined parts, preparing surfaces for welding, or performing maintenance on heavy machinery, this carbide burr delivers the consistency and longevity required for professional results.
