01V646 - Walter SG-3 Double Cut Carbide Burr with 6-Inch Extended Shank

Precision Engineering for Hard-to-Reach Applications

The Walter 01V646 Carbide Burr represents the intersection of durability and precision engineering in the field of abrasive tooling. Designated as an SG-3 shape with a Double Cut (DC) pattern and an L6 extended shank, this tool is specifically manufactured to address the challenges of material removal in deep cavities, internal piping, and complex contours. Walter Surface Technologies utilizes only the finest quality tungsten carbide in the production of these burrs, ensuring a microstructure that resists thermal shock and maintains a sharp cutting edge significantly longer than standard high-speed steel alternatives.

The SG-3 geometry, commonly referred to as a "Pointed Tree" shape, is characterized by its ability to grind into acute angles and follow curved surfaces effectively. This makes it an indispensable asset for mold making, pattern work, and precision mechanical repairs. The "DC" or Double Cut fluting design features cross-cut teeth that effectively break down chips into granular sizes. This not only prevents the loading of the flutes—a common issue with single cut burrs on softer metals—but also reduces operator fatigue by minimizing the "pulling" action often associated with rotary files. The result is a smoother surface finish and increased control during operation.

A critical feature of the 01V646 is its 6-inch extended shank. Standard burrs often fail to reach the root of deep welds or the interior surfaces of long channels. The extended shank on this model is hardened and precision-ground to ensure perfect concentricity. Runout is virtually eliminated, which is crucial when operating at the high RPMs required for carbide tooling. Vibration-free operation protects both the die grinder bearings and the workpiece, ensuring that the material removal is consistent and accurate. This product is engineered for industrial environments where tool longevity and performance reliability are paramount.

In summary, the Walter 01V646 offers a robust solution for specialized grinding tasks. Its combination of a versatile cutting head, advanced flute geometry, and extended reach makes it a requisite tool for MRO professionals and machinists seeking to optimize their deburring and finishing processes.
