Walter Allsteel SC-3 Double Cut Carbide Burr 3/8 x 3/4

Heavy-Duty Weld Cleaning and Prep with Walter Carbide Burrs

For professional welders and fabricators, the Walter Allsteel Carbide Burr SC-3 (01W306) is an essential addition to your die grinder arsenal. When prepping metal for a critical weld or cleaning up a finished joint, you need a tool that cuts aggressively yet leaves a clean surface. The Walter Allsteel series is specifically formulated to withstand the rigors of heavy fabrication, cutting through mild steel, stainless steel, and hard alloys without bogging down or dulling prematurely.

The 01W306 features a Double Cut (DC) flute design, which is the preferred choice for most welding applications. Unlike single cut burrs that produce long, sharp shavings, the double cut pattern creates small, manageable chips. This feature is crucial for welders as it prevents the tool from catching or "skipping" on the metal surface, providing the steady control needed for precision work. The SC-3 shape—a cylinder with a rounded nose—is perfect for grinding inside corners, blending fillet welds, and working in confined spaces where a flat-ended burr might gouge the base metal.

Manufactured in the USA, Walter burrs are known for their concentricity and balance. A balanced burr means less chatter and vibration in your die grinder, which translates to less hand fatigue during long shifts. The 3/8-inch head diameter provides a good balance between material removal rate and accessibility, while the 1/4-inch shank fits all standard pneumatic and electric die grinders. Whether you are beveling plate edges for a V-groove or dressing a cap pass, the Walter Allsteel SC-3 delivers the performance and durability required in professional welding shops.

Why Choose Double Cut?

• Better Control: Reduces the "pulling" action, making it easier to guide the tool.
• Finer Finish: Leaves a smoother surface that requires less secondary sanding.
• Efficient Chip Evacuation: Prevents loading and keeps the cutting edges cool.
• Versatility: Suitable for a wide range of metals including stainless and high-tensile steel.
