Walter SF-42 Double Cut Tungsten Carbide Burr 1/8-Inch Shank

Superior Weld Preparation and Finishing

For professional welders and fabricators, the finish is just as important as the weld itself. The Walter 01V022 Carbide Burr SF-42 DC is your go-to solution for efficient weld cleaning, defect removal, and surface preparation. Built with premium tungsten carbide, this rotary burr cuts through tough materials like stainless steel and hard alloys without losing its edge, saving you time and money on consumable replacements. The "Double Cut" design is a favorite among fabricators because it offers a balanced feel—it bites into the metal for rapid removal but remains easy to control, reducing the likelihood of the tool "walking" across your workpiece.

The SF-42 shape, known as a tree with a radius end, is incredibly useful for accessing tight corners and curved geometries often found in pipe welding and complex fabrication assemblies. It allows you to grind out porosity or slag inclusions with surgical precision or enlarge mounting holes to exact tolerances. Because it produces small chips rather than long, sharp slivers, cleanup is faster and safer for the operator. The 1/8-inch shank is compatible with smaller, pencil-style die grinders, offering you the dexterity needed for fine detail work.

Don't settle for inferior grinding bits that vibrate and dull quickly. Walter's commitment to quality means this burr runs true, protecting your tools and your hands from excessive vibration fatigue. Whether you are smoothing out a root pass, chamfering edges for better penetration, or simply cleaning up a finished piece, the Walter SF-42 DC provides the aggressive cut and smooth finish that high-quality welding demands.
