01V036 - Walter SL-3 Non-Ferrous Carbide Burr for Aluminum

Precision Material Removal for Non-Ferrous Applications

The Walter 01V036 Carbide Burr SL-3 NF represents the pinnacle of rotary file engineering, specifically tailored for the unique challenges of machining non-ferrous metals. In industrial environments where aluminum, copper, and brass are frequently processed, standard carbide burrs often fail due to material loading—where the soft metal adheres to the cutting flutes, rendering the tool ineffective. Walter has addressed this issue with a specialized Non-Ferrous (NF) cut geometry. This design features wide, deeply ground flutes that facilitate rapid chip evacuation, preventing the clogging that typically plagues standard diamond or double-cut burrs when used on soft alloys.

Manufactured from the finest grade of tungsten carbide, this burr offers exceptional hardness and wear resistance, ensuring a service life that significantly outlasts high-speed steel alternatives. The SL-3 shape, characterized as a Taper with a Radius End (or Cone with Ball Nose), is particularly versatile. It allows operators to work on contoured surfaces, enlarge holes, and finish fillets with precision. The tapered profile provides access to angled areas, while the radiused tip allows for smooth blending of curves without gouging the workpiece.

Critical to the performance of any high-speed rotary tool is its balance. Walter manufactures these burrs with exacting standards of concentricity. A perfectly balanced burr eliminates chatter and vibration at high RPMs, which not only improves the surface finish of the part but also protects the bearings of the pneumatic or electric die grinder. This attention to manufacturing detail results in a tool that runs smoother, cuts faster, and reduces operator fatigue during extended use. For MRO professionals and fabricators seeking reliability and efficiency in aluminum removal, the Walter SL-3 NF is an essential component of the abrasive toolkit.
