Walter SD-3 Double Cut Carbide Burr 3/8 Inch Ball Shape

Heavy-Duty Deburring for Professional Fabricators

For welders and fabricators, time spent on cleanup and prep is time away from laying beads. The Walter Allsteel Carbide Burr SD-3 is built to speed up that process. This 'Double Cut' burr is a workhorse for the welding shop, designed to chew through mild steel, stainless steel, and tough alloys with ease. The double cut tooth pattern creates smaller chips rather than long, sharp slivers, making cleanup safer and easier while leaving a smoother finish that often requires no further sanding.

The ball shape (SD-3) is an essential profile for any welder's toolbox. It excels at cleaning out porosity in welds, prepping cracks for repair welding, and smoothing out concave fillet welds. Its 3/8-inch diameter allows it to fit into tight corners and radiused areas where flat or cylindrical burrs simply can't reach. Because it is manufactured by Walter, you can trust the carbide grade to withstand the high heat generated during aggressive grinding without softening or chipping prematurely.

Vibration is the enemy of precision and comfort. Cheap burrs often wobble, causing chatter marks on your work and numbing your hands. The Walter 01W310 is balanced to run true, allowing you to guide the tool smoothly along the weld seam or edge. Whether you are opening up a hole that's slightly undersized or blending a repair on a casting, this burr gives you the control and bite you need to get the job done right the first time.
