OVERVIEW

High-Performance Aluminum Grinding Burr

Welders know that prepping aluminum is a different beast compared to steel. The Walter 01V016 Carbide Burr SF-5 with Non-Ferrous (NF) cut is the solution for fabricators who need to clean, prep, or finish aluminum welds without the frustration of a clogged tool. Standard cross-cut burrs will gum up almost instantly on aluminum, but this specialized NF burr features wide, deep flutes that shovel material away as fast as you can grind it. This means you spend more time working and less time stopping to clean your bit.

The SF-5 shape (Tree with Radius End) is particularly useful in welding applications. Its pointed nose allows access into tight corners and fillet welds, while the radiused body is perfect for blending contours and smoothing out wash passes. Made from top-tier tungsten carbide, this burr bites into the metal aggressively, leaving a smooth finish that is often ready for welding or final polishing. It is an essential tool for any welder working with aluminum trailers, boat hulls, or aerospace components.

Beyond just aluminum, this burr excels on other non-ferrous materials like copper, brass, and even hard plastics. The precision balance of Walter burrs ensures that your die grinder runs smoothly, reducing the "chatter" that can ruin a delicate finish or cause hand fatigue during long shifts. Upgrade your abrasive arsenal with a tool designed specifically for the metallurgy you are working on.

Welder-Centric Features

Aluminum Specific: The NF cut is engineered to shear soft metal cleanly rather than grinding and melting it.
Versatile Shape: SF-5 profile handles both tight access work and broad surface blending.
Smooth Operation: Perfect concentricity means less chatter and better control over your grind.

FAQ

NF stands for 'Non-Ferrous'. This cut pattern is specifically designed with wider flutes to prevent clogging when grinding soft materials like aluminum.

The SF-5 is a 'Tree with Radius End' shape. It has a pointed nose that widens out, with a curved profile, making it excellent for contoured surfaces.

While tungsten carbide is hard enough to cut steel, the NF (Non-Ferrous) geometry is too aggressive for hard steel and may chip. It is best reserved for soft metals.

This burr is designed for use in a pneumatic or electric die grinder. Ensure your collet size matches the burr's shank (typically 1/4").

If you are using this NF burr and it clogs, you may be running it too slow or applying excessive pressure. However, this burr resists clogging much better than standard cuts.

It is made from high-grade Tungsten Carbide, which is significantly harder and more durable than High-Speed Steel (HSS).

Yes, the Non-Ferrous cut is excellent for hard plastics as the wide flutes prevent the plastic from melting and loading the tool.
