OVERVIEW

Precision Grinding with Extended Reach

The Walter 01V615 Carbide Burr is a high-performance rotary file designed for professional metalworking applications requiring both aggression and precision. Part of Walter's premium line of tungsten carbide burrs, this tool is engineered to deliver rapid stock removal while maintaining a long service life. The specific SF-5 shape (Tree with Radius End) makes it incredibly versatile, allowing for the effective grinding of contoured surfaces, rounding off edges, and cleaning out concave areas.

What sets this specific model apart is its L6 configuration, which denotes an extended 6-inch shank. In industrial maintenance and fabrication, operators frequently encounter burrs or welds located deep inside pipes, engine manifolds, or complex machinery housings. Standard length burrs simply cannot reach these areas safely. The 01V615 bridges this gap, providing the necessary reach while maintaining the rigidity required for stable grinding. The 1/4-inch shank is ground to exacting tolerances to ensure it fits securely in standard die grinders without slipping.

The Double Cut (DC) flute geometry is another critical feature. Unlike single cut burrs that produce long, sharp stringer chips, the double cut design incorporates cross-flutes that break the material into small, manageable granular chips. This not only makes waste removal easier but also significantly reduces operator fatigue by minimizing the "pulling" action often felt with single cut tools. The result is a smoother finish and better control, even when working on harder materials like stainless steel and high-tensile alloys.

Key Technical Benefits

Material Compatibility: Excellent for use on steel, stainless steel, and cast iron.
Vibration Control: Manufactured with strict concentricity standards to prevent chatter, protecting both the workpiece and the die grinder bearings.
Heat Resistance: High-grade tungsten carbide withstands the high temperatures generated during heavy stock removal.

FAQ

SF-5 refers to the standard shape and size code for the burr. 'SF' indicates a Tree Shape with a Radius End, and '5' typically denotes a head diameter of 1/2 inch and a length of cut of 1 inch.

Double Cut burrs have cross-flutes that break chips into smaller pieces. This allows for faster material removal, a smoother finish, and better operator control compared to single cut burrs.

The extended shank (L6) is essential for reaching deep into pipes, castings, or machinery where a standard 2-inch or 3-inch burr cannot reach.

This tungsten carbide burr is designed for use on ferrous metals, including carbon steel, stainless steel, cast iron, and high-strength alloys.

For a 1/2" diameter carbide burr, the recommended speed is typically between 15,000 and 22,000 RPM. Always consult the manufacturer's specific speed charts.

While it may physically fit if the drill chuck accepts 1/4" shanks, standard drills usually do not spin fast enough (RPM) for carbide burrs to work effectively. A die grinder is the recommended tool.

Double cut burrs can clog when used on soft, non-ferrous metals like aluminum. For aluminum, an 'Alu-Cut' or single cut burr with wide flutes is recommended to prevent loading.

Tungsten carbide is extremely hard but can be brittle. Store the burr in a way that prevents it from banging against other tools to avoid chipping the cutting edges.
