Walter SG-3 Double Cut Carbide Burr with 6-Inch Extended Shank

Reach Deep and Grind Smooth with Walter

Every welder knows the frustration of spotting a defect or a rough patch in a spot where your standard grinder just won't fit. Maybe it's inside a piece of heavy wall pipe, at the bottom of a deep box channel, or tucked into a tight gusset. That is exactly where the Walter 01V646 Carbide Burr shines. This isn't just another rotary file; it is a problem solver designed with a 6-inch extended shank that acts like an extension of your hand, letting you reach deep into the workpiece without losing control or visibility.

The business end of this tool features the SG-3 "Pointed Tree" shape. This is one of the most versatile shapes for fabrication because the pointed tip allows you to dig into tight corners and V-grooves, while the curved body lets you blend contours seamlessly. Whether you are prepping a root pass, cleaning up porosity, or blending a fillet weld in a hard-to-reach area, the SG-3 shape gives you the adaptability you need. Plus, it features Walter's Double Cut technology. If you've ever had a burr catch and walk across your part, ruining the finish, you'll appreciate the Double Cut. The cross-cut teeth create smaller chips, which means the tool cuts smoother, stays cooler, and is much easier to control, even when you are leaning into it at full extension.

Durability is key in the shop, and Walter doesn't cut corners. This burr is crafted from premium tungsten carbide, meaning it holds its edge through the toughest jobs on steel, stainless, and cast iron. The shank is perfectly balanced, so you won't feel that hand-numbing vibration that cheaper extended bits often produce. Less vibration means you can work longer with more precision, resulting in a better finish and less rework.

Don't let tight spaces slow down your production. Equip your die grinder with the Walter 01V646 and turn those difficult, hard-to-reach grinding jobs into quick, easy work. It’s the reliable, heavy-duty companion you need for intricate fabrication and finishing tasks.
