01W646 - Walter SG-3 Double Cut Carbide Burr with 6-Inch Extended Shank

Precision Engineering for Superior Metal Removal

The Walter ALLSTEEL™ Carbide Burr (SKU: 01W646) represents the pinnacle of American-made abrasive technology. Designed specifically for industrial applications requiring precision and durability, this SG-3 shaped burr features a Pointed Tree profile that is essential for working on concave surfaces and tight angles. The "Double Cut" geometry is a critical feature for operators seeking a balance between aggressive material removal and surface finish quality. Unlike single cut burrs, the double cut design incorporates cross-cut teeth that effectively break down chips into smaller, manageable granular particles. This not only prevents the tool from loading up but also significantly reduces operator fatigue by minimizing the "pulling" action often associated with rotary files.

One of the standout features of this specific model is its 6-inch extended steel shaft. In many machining and fabrication scenarios, standard length burrs simply cannot reach deep into castings, pipes, or complex assemblies. The 01W646 solves this problem, providing the necessary reach while maintaining the rigidity required for precise control. Manufactured with strict quality control standards in the USA, Walter carbide burrs ensure concentricity and balance, which translates to lower vibration levels. This is particularly beneficial for protecting the bearings of high-speed die grinders and CNC machinery, ensuring a longer lifespan for both the consumable and the power tool.

The ALLSTEEL™ formulation is optimized for ferrous metals, making it the go-to choice for working with mild steel, stainless steel, and cast iron. Whether you are deburring a freshly machined part, enlarging a hole, or smoothing out a weld seam, this carbide burr delivers consistent performance. The superior machining process used to create these burrs guarantees consistent cutting angles, resulting in an exceptionally smooth finish on the workpiece. For professionals who demand reliability and efficiency in their material removal processes, the Walter 01W646 is an indispensable tool in the abrasive arsenal.
