01W308 - Walter SC-5 Non-Ferrous Carbide Burr - 1/2 Inch Aluminum Cut

Precision Grinding for Non-Ferrous Materials

The Walter Allsteel Carbide Burr SC-5 NF (SKU: 01W308) represents the pinnacle of tooling engineering for soft metal applications. In industrial environments where aluminum, copper, brass, and bronze are fabricated, standard double-cut burrs often fail due to material loading. The soft nature of these metals causes chips to weld into the flutes, rendering the tool ineffective and increasing heat generation. Walter’s Non-Ferrous (NF) cut geometry addresses this physics challenge directly with a wide, open flute design and a high relief angle. This configuration allows for massive chip evacuation, keeping the cutting edges clean and cool even during aggressive stock removal.

Manufactured in the USA, this burr features the industry-standard SC-5 shape—a cylinder with a radius end. This profile is exceptionally versatile, allowing operators to mill flat surfaces with the side of the burr while simultaneously grinding fillets or contoured radii with the nose. The 1/2-inch cutter diameter provides a substantial contact area for leveling welds, while the 1-inch length of cut offers ample reach. The tool is constructed from premium-grade tungsten carbide, brazed to a hardened steel shank. This construction ensures that the head maintains its cutting edge under high thermal stress while the shank retains the toughness to resist fracture under side loads.

Precision balancing is a hallmark of the Walter Allsteel line. The 01W308 is ground to tight concentricity tolerances, which significantly reduces vibration (chatter) at high RPMs. Reduced chatter not only improves the surface finish of the workpiece but also reduces wear on the die grinder’s bearings and minimizes operator fatigue (Hand-Arm Vibration Syndrome). For MRO professionals and machinists seeking a reliable, high-performance solution for non-ferrous deburring and shaping, this carbide burr delivers consistent, measurable results.
