Walter ALLSTEEL SL-4 Double Cut Carbide Burr - 1/2 Inch x 1-1/8 Inch

Heavy-Duty Deburring for Professional Fabrication

Welders know that the finishing stage is just as critical as laying the bead, and the Walter 01W332 ALLSTEEL™ Carbide Burr is built to handle the toughest cleanup jobs in the shop. This SL-4 (Cone with Ball Nose) rotary file is an essential tool for grinding out fillet welds, prepping joints, and smoothing out rough edges on complex metal shapes. Unlike cheaper alternatives that dull quickly or vibrate excessively, Walter burrs are precision-balanced to run smooth, reducing hand fatigue during long grinding shifts.

The "Double Cut" tooth design is a game-changer for fabricators working with mild steel, stainless steel, or hard alloys. Instead of producing long, sharp slivers that can injure the operator or clog the tool, the double-cut pattern shreds material into fine, harmless chips. This allows for aggressive material removal without sacrificing control, letting you grind down excess weld metal quickly while leaving a finish smooth enough for painting or polishing. The ball nose tip is particularly useful for blending radii and working inside pipes or channels where a flat-ended burr would gouge the workpiece.

Equipped with a standard 1/4-inch hardened steel shank, this burr fits securely into any pneumatic or electric die grinder. It is built to withstand the high torque and heat generated during heavy grinding applications. When you need a tool that bites into the metal and stays sharp job after job, the Walter 01W332 is the reliable choice for professional metalworkers demanding quality and performance.
