01V069 - Walter SL-4 Carbide Burr for Aluminum - 1/2 Inch Diameter

Don't Let Aluminum Clog Your Grind

Every welder knows the frustration of grinding aluminum: you start working, and within seconds, your standard burr is packed full of soft metal, rendering it useless. The Walter 01V069 Carbide Burr solves this problem with a purpose-built design for non-ferrous metals. If you are fabricating aluminum tanks, repairing boat hulls, or customizing automotive parts, this SL-4 Cone shape burr is the tool you need in your die grinder to keep the work moving.

The secret lies in the aggressive, open flute design. Instead of small chips getting trapped, this burr shears off long chips of aluminum and ejects them immediately. This means you can grind faster, cooler, and with significantly less pressure. The SL-4 Cone shape (1/2" x 1-1/8") is particularly useful for welders because it allows you to grind out fillet welds, bevel edges for penetration, or smooth out tight corners where a flat disc simply cannot reach. The 1/4" shank fits your standard die grinder collet securely.

Walter is known for making abrasives that last, and this carbide burr is no exception. It runs true without the wobble that cheaper bits often have, which saves your bearings and your hands from excessive vibration. Whether you are deburring a cut edge, enlarging a hole, or blending a weld seam on aluminum or copper, this tool provides the control and bite you need to get a professional finish.
