01W309 - Walter SD-1 Double Cut Carbide Burr for Steel and Stainless

Precision Material Removal for Industrial Applications

The Walter Allsteel™ Carbide Burr (SKU: 01W309) represents the pinnacle of American manufacturing in the field of rotary abrasives. Designed specifically for heavy-duty industrial environments, this SD-1 ball-shaped burr is engineered to deliver consistent, high-performance results on steel, stainless steel, and other ferrous alloys. In high-volume fabrication and MRO operations, tool longevity and cycle time are critical; Walter addresses these needs by utilizing premium-grade tungsten carbide substrates that resist wear and maintain cutting edge integrity even under thermal stress.

Manufactured using advanced CNC machining and grinding techniques, every Allsteel burr guarantees exceptional concentricity. This precision balance minimizes vibration at high RPMs, protecting both the pneumatic turbine of your die grinders and the bearings of automated CNC equipment. The "Double Cut" geometry is a key feature for industrial users, as it incorporates cross-cut flutes that effectively break down chips into granular swarf rather than long, dangerous stringers. This not only improves operator safety but also prevents the loading of the flutes, ensuring continuous cutting action without the need for frequent cleaning stops.

The SD-1 shape is particularly versatile for MRO tasks, allowing technicians to reach into concave surfaces, deburr drilled holes, and blend weld roots in confined spaces. Whether utilized in a manual die grinder or a robotic cell, the 01W309 provides a low tool load, reducing energy consumption and mechanical wear on power sources. By choosing Walter Allsteel carbide burrs, procurement managers and facility supervisors invest in a consumable that balances aggressive material removal rates with a superior surface finish, ultimately reducing secondary finishing steps and lowering total production costs.
