01W331 - Walter SL-3 Double Cut Carbide Burr for Steel and Stainless

Precision Grinding with Walter Allsteel Carbide Burrs

The Walter 01W331 Allsteel Carbide Burr (Shape SL-3) is a premium industrial tool designed for heavy-duty stock removal and precision finishing. Manufactured in the USA, this burr is engineered to meet the rigorous demands of metal fabrication, MRO, and machining environments. The SL-3 shape, known as a Taper with Radius End or Cone Ball Nose, is particularly effective for accessing tight angles, contouring curved surfaces, and deburring complex geometries where a standard cylindrical burr cannot reach.

Part of the renowned Allsteel™ series, this burr features a sophisticated Double Cut geometry. Unlike single-cut alternatives, the double-cut design incorporates cross-cut flutes that break down metal chips into smaller, manageable granular particles. This significantly reduces tool loading and prevents the burr from 'pulling' or 'walking' across the workpiece, granting the operator superior control and reducing fatigue during extended use. The result is a faster removal rate combined with a smoother surface finish, minimizing the need for secondary sanding or polishing steps.

Constructed from high-grade tungsten carbide, the 01W331 offers exceptional hardness and heat resistance, maintaining its cutting edge even under high-temperature grinding conditions common with stainless steel and hard alloys. The precise manufacturing process ensures perfect concentricity between the head and the 1/4-inch shank, eliminating chatter and vibration that can damage expensive die grinders or compromise the workpiece. Whether you are beveling edges, cleaning up welds, or enlarging holes, the Walter Allsteel SL-3 burr delivers consistent, professional performance.

Key Applications

• Deburring: Efficiently removes heavy burrs from cut steel and stainless steel edges.
• Contouring: The tapered radius shape is ideal for smoothing fillets and internal curves.
• Weld Preparation: Cleans and preps joints for welding or removes excess weld metal post-fabrication.
• Maintenance: Essential for MRO tasks requiring material removal in hard-to-reach areas.
