01V072 - Walter SN-4 Double Cut Carbide Burr - Inverted Cone

Precision Engineered for Industrial Performance

The Walter SN-4 Double Cut Carbide Burr (01V072) represents the pinnacle of rotary file technology, engineered specifically for heavy-duty industrial applications. Manufactured from the highest grade of tungsten carbide, this tool is designed to withstand the extreme heat and stress generated during high-speed stock removal operations. The SN-4 classification denotes an Inverted Cone geometry, a specialized shape essential for difficult-to-reach areas, rear-side chamfering, and creating V-cuts in metal fabrication.

Crucial to the performance of the 01V072 is its Double Cut flute pattern. Unlike single-cut burrs that produce long, sharp chips, the double-cut design features cross-cut teeth that break material down into small, manageable granular chips. This significantly reduces tool loading and allows for more aggressive feed rates without sacrificing control. For MRO professionals and machinists, this means reduced cycle times and a lower cost per cut.

Walter Surface Technologies prioritizes concentricity in their manufacturing process. The shank of this burr is precision-ground to ensure it runs perfectly true in the collet of a pneumatic or electric die grinder. This balance minimizes vibration, which protects the bearings of the power tool and prevents the "chatter" marks often associated with inferior abrasive products. Whether working on high-tensile steel or austenitic stainless steel, this burr delivers consistent, measurable results.
