OVERVIEW

Reach Further, Grind Smoother

For professional welders, access is everything. The Walter Carbide Burr SF-3 DC L6 (SKU: 01V614) is your solution for those frustrating, hard-to-reach spots inside pipes, channels, and tight structural corners. With a 6-inch extended shank, this tool acts as an extension of your hand, allowing you to clean up root passes, blend welds, and remove spatter in areas where a standard 2-inch burr would leave you stranded. It turns difficult, knuckle-busting jobs into smooth, controlled tasks.

The "Double Cut" design is a welder's best friend. Unlike single cut burrs that can grab and pull, the cross-cut flutes on this Walter burr provide a smooth, steady cutting action that is easy to control. This geometry produces small chips instead of sharp, stringy swarf, keeping your workspace cleaner and safer. The SF-3 tree shape with a radius nose is perfect for following the natural curve of a fillet weld or smoothing out concave surfaces without gouging the base metal.

Walter Surface Technologies is known for quality, and this burr is no exception. The tungsten carbide head stays sharp longer, meaning fewer tool changes and less downtime. The shank is perfectly balanced to run true in your die grinder, reducing the vibration that causes hand numbness after a long day of fabrication. Whether you are prepping a joint for a critical weld or putting the final polish on a stainless steel project, trust the reach and reliability of the Walter 01V614 to get the job done right.

FAQ

The 'L6' designation indicates that this carbide burr features an extended shank with a total length of approximately 6 inches, allowing for reach into deep cavities and hard-to-access areas.

This double cut carbide burr is designed for use on ferrous metals such as steel, stainless steel, and cast iron. It is not recommended for soft non-ferrous metals like aluminum, which may clog the flutes.

Double Cut burrs, like this one, have cross-cut flutes that produce smaller chips and a smoother finish, offering better operator control. Single Cut burrs remove material faster but produce long, sharp chips and a rougher finish.

For a 3/8" diameter carbide burr, the recommended speed is typically between 20,000 and 30,000 RPM. Always refer to the specific manufacturer guidelines and ensure your die grinder does not exceed the maximum safe speed.

Concentricity ensures the burr spins perfectly true. In a long shank tool (6 inches), any imbalance is amplified, causing dangerous vibration, chatter, and potential bending of the shank. Walter burrs are manufactured for perfect balance.

It is not ideal. Double cut burrs tend to 'load up' or clog with soft aluminum. For aluminum, you should use a burr with an 'Alu-Cut' or non-ferrous geometry to prevent clogging.

Always wear a face shield and safety glasses (double eye protection), hearing protection, and gloves. Long shank burrs can be hazardous if not handled correctly; ensure the burr is fully inserted into the collet.

The SF-3 is a 'Tree Shape with Radius End'. It has a pointed nose that is rounded off, making it excellent for grinding contoured surfaces and getting into rounded corners without digging in.
