The Walter Allsteel™ Carbide Burr (SKU: 01W311) represents the pinnacle of rotary tooling for industrial metalworking. Featuring the industry-standard SD-6 ball shape geometry, this tool is expertly engineered for precision deburring, contouring, and material removal on ferrous metals. Manufactured in the USA using advanced CNC grinding processes, this heavy-duty tungsten carbide burr utilizes a double-cut flute pattern. The double-cut design incorporates right and left-hand helical flutes, which work in tandem to produce smaller, granular chips (swarf) rather than long, dangerous slivers. This chip-breaking action significantly reduces tool loading, improves operator control by minimizing "pulling" or "climbing," and delivers a superior surface finish on the workpiece.
Designed for seamless compatibility with pneumatic and electric die grinders accepting a standard 1/4" shank, the SD-6 profile offers a substantial 5/8" head diameter and a 9/16" length of cut. The spherical ball shape is particularly effective for machining concave surfaces, rounding edges, blending fillet welds, and deburring the inside of holes where cylindrical burrs cannot reach. Walter's rigorous quality control and manufacturing process ensure exceptional concentricity, minimizing vibration at high RPMs. This balance is critical for protecting the bearings of the power tool and reducing the risk of chatter marks on the substrate.
The Allsteel™ series is specifically optimized for use on mild steel, stainless steel, and other tough ferrous alloys. The carbide grade selected by Walter provides high hot hardness, allowing the burr to maintain its cutting edge even under the thermal stress of aggressive stock removal. Whether used in a fabrication shop, foundry, or maintenance department, the 01W311 delivers consistent cutting action and extended tool life, reducing the frequency of tool changes and lowering overall production costs.
