OVERVIEW

The Heavy-Duty Burr for Serious Fabrication

When you are deep in a fabrication project, the last thing you need is a burr that bounces, chatters, or dulls the moment it touches a stainless steel weld. The Walter 01V035 SL-4 Carbide Burr is built for welders who demand performance and longevity from their consumables. This isn't just another rotary file; it is a high-performance tungsten carbide tool designed to eat through metal while leaving a finish you can be proud of. If you work with stainless steel, you know how easily it can work-harden if your tool isn't cutting efficiently. The Walter SL-4 is engineered to cut aggressively yet smoothly, preventing heat buildup and keeping your workpiece workable.

The "SL-4" designation refers to its shape: a tapered cone with a rounded (radius) nose. This is one of the most useful shapes in a welder's arsenal. It allows you to get into tight angles, clean out the roots of welds, or enlarge holes that are slightly out of spec. The rounded tip is perfect for blending contours without gouging the base metal, giving you a smooth transition every time. Because it features a double-cut (alternating diamond) pattern, you get better control. Single-cut burrs can sometimes pull the grinder, but this double-cut design stabilizes the tool, giving you a steady hand even when removing heavy stock.

Durability is key in a job shop. You don't want to be swapping out burrs every ten minutes. Walter's premium tungsten carbide construction means this burr stays sharp longer, giving you more arc time and less downtime. It creates small, harmless chips instead of long, sharp slivers, making cleanup easier and safer. Whether you are prepping a joint, cleaning up spatter, or fine-tuning a fit-up, the Walter 01V035 is the reliable partner your die grinder needs.

FAQ

The SL-4 shape is a Taper with a Radius End (also known as a Cone with Ball Top). This shape is ideal for working in tight corners, blending contours, and enlarging holes.

Yes, the Walter 01V035 is manufactured from high-grade tungsten carbide and features a cutting geometry specifically suitable for stainless steel, as well as standard steel and other alloys.

This refers to a 'double cut' flute geometry. It creates smaller chips for easier evacuation, reduces tool loading, and provides a smoother finish compared to single-cut burrs.

This burr is designed for use with pneumatic or electric die grinders. Ensure your grinder's collet matches the shank size of the burr and operates at the recommended RPM.

Concentricity ensures the burr spins perfectly true. This prevents chatter (vibration), which can damage the workpiece, wear out the grinder bearings, and cause operator fatigue.

While it can cut aluminum, double-cut burrs like this one may load up (clog) with soft aluminum. For aluminum, a single-cut or specific 'aluminum cut' burr is generally recommended.

The tapered design allows the burr to enter smaller holes and gradually enlarge them as the wider part of the burr engages, while the radius tip prevents gouging.

Tungsten carbide is significantly harder and more heat-resistant than high-speed steel (HSS), allowing it to cut faster and last much longer, especially on hard materials like stainless steel.
