01V631 - Walter SL-3 Double Cut Carbide Burr 6-Inch Shank

Precision Grinding for Hard-to-Reach Areas

The Walter 01V631 Carbide Burr (SL-3 DC L6) is an industrial-grade rotary file designed to tackle the most challenging deburring and shaping tasks. Engineered by Walter Surface Technologies, this tool combines premium materials with advanced geometry to deliver superior performance in metalworking applications. The defining feature of this model is its 6-inch extended shank, which provides the necessary reach to grind, deburr, and finish surfaces inside pipes, channels, and deep recesses that standard length burrs simply cannot access.

Constructed from the finest tungsten carbide, this burr is built to withstand the high heat and stress of heavy-duty grinding. The SL-3 shape (Cone with Radius End) is particularly effective for contouring and working in tight corners where a rounded profile is required to blend surfaces smoothly. The "DC" designation stands for Double Cut, a flute geometry that employs cross-cut teeth. This design efficiently breaks down chips into small, manageable granular particles, preventing loading and ensuring a smoother finish compared to single-cut alternatives. It also reduces operator fatigue by minimizing the "pulling" action often associated with rotary files.

Perfect concentricity is a hallmark of Walter burrs. This precision balance eliminates vibration, protecting both your die grinder and the workpiece while ensuring operator comfort during prolonged use. Whether you are prepping welds, enlarging holes, or cleaning up castings, the 01V631 delivers consistent, aggressive material removal on steel, stainless steel, and cast iron.
