Walter SD-42 Double Cut Carbide Burr 1/2" Ball Shape

Smooth Control and Fast Removal

Take your metal finishing to the next level with the Walter SD-42 Double Cut Carbide Burr. If you are tired of burrs that dull quickly or bounce uncontrollably on the workpiece, this premium tungsten carbide tool is the solution. The ball shape (SD-42) is incredibly versatile, making it perfect for contouring, hollowing out areas, or enlarging holes in preparation for welding. Because it is built by Walter, you can trust that the shank is perfectly straight and the head is balanced, giving you a smooth run every time you pull the trigger on your die grinder.

The double cut design is what truly sets this burr apart for welders and fabricators. The alternating tooth pattern chews through metal rapidly but leaves a surprisingly smooth finish, reducing the amount of follow-up sanding required. It creates small, non-sharp chips rather than long, dangerous slivers, keeping your workspace cleaner and safer. This burr bites into the metal without grabbing, giving you excellent control even when working on hard materials like stainless steel welds or heavy structural steel.

Durability is key in any shop environment. The high-quality tungsten carbide construction resists heat buildup, preventing the cutting edges from softening or chipping prematurely. Whether you are cleaning up a root pass, deburring a freshly cut pipe, or sculpting a complex metal part, the Walter 01V021 stands up to the heat and pressure of daily professional use. Add this essential bit to your rotary tool kit and experience the difference that precision engineering makes in your daily grinding tasks.
