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

Smooth Control and Flawless Finishes

Take your metalworking projects to the next level with the Walter Allsteel™ Carbide Burr, model 01W309. If you are a welder or fabricator looking for a tool that bites into metal without fighting you, this SD-1 double cut burr is the answer. Known for its "ball" shape, the SD-1 is an essential profile for your die grinder arsenal, perfect for hollowing out areas, smoothing concave welds, or cleaning up the edges of a freshly drilled hole. Unlike cheaper imports, this burr is made in the USA with high-quality tungsten carbide, meaning it stays sharp longer and saves you money on replacements.

The magic of this burr lies in its "Double Cut" design. Standard single-cut burrs can sometimes bounce or "chatter" across the workpiece, leaving a rough surface and tiring out your hands. The Walter Allsteel features cross-cut teeth that stabilize the tool, giving you incredible control. It shreds steel and stainless steel into tiny, harmless chips rather than throwing hot, sharp needles at you. This makes it much easier to guide the tool exactly where you want it, allowing for precision sculpting and deburring without the struggle.

Whether you are prepping a joint for a critical weld, cleaning up spatter, or modifying a custom part, the 01W309 delivers a professional finish every time. It is designed to work seamlessly with standard air or electric die grinders. The superior balance of the tool means less vibration, so you can work longer without fatigue. Upgrade your abrasive kit with Walter's Allsteel series and experience the difference that premium engineering makes in your daily fabrication tasks.
