OVERVIEW

Stop Clogging and Start Grinding

Every welder knows the frustration of grinding aluminum. You start a cut, and within seconds, your burr is packed solid with soft metal, forcing you to stop and clean it out or grab a new tool. The Walter Carbide Burr SC-5 NF is the solution to this common headache. Specifically engineered with a "Non-Ferrous" cut, this burr features wide, deep flutes and a coarse pitch that aggressively shreds soft metals while ejecting chips instantly. This self-cleaning action means you can grind aluminum, magnesium, and brass continuously without the tool loading up.

The SC-5 shape is a workhorse in the shop. Its cylindrical profile with a radius nose (bull nose) allows you to attack material from multiple angles. You can smooth out flat welds, dig into corners, or contour rounded surfaces without changing bits. This versatility makes it an essential tool for anyone fabricating aluminum tanks, repairing boat hulls, or customizing automotive parts. The 1/4-inch shank is compatible with standard die grinders, making it a drop-in upgrade for your existing toolkit.

Built for Speed and Comfort

Time is money, and the Walter SC-5 NF is built to remove material fast. The high-grade tungsten carbide construction allows for higher rotational speeds and more aggressive feed rates compared to standard bits. Despite its aggressive cutting ability, the tool is precision-balanced to run smoothly. Less vibration means you have better control over the grinder, resulting in cleaner cuts and less strain on your hands and wrists at the end of a long shift.

Key Features for Welders

No More Clogging: Open flute design keeps the burr cutting freely on gummy metals.
Versatile Shape: Radius end handles both surface grinding and fillet work.
Long Life: Premium carbide stays sharp longer, saving you money on replacements.
Smooth Operation: Balanced manufacturing reduces chatter and improves finish quality.

Don't let clogged tools slow down your production. Equip your shop with the Walter SC-5 NF and experience the difference a purpose-built aluminum burr makes.

FAQ

SC-5 is a standard industry shape code referring to a Cylindrical burr with a Radius End (also known as a Bull Nose). It typically measures 1/2 inch in diameter with a 1-inch length of cut.

'Nf' stands for Non-Ferrous. This indicates the burr has a specialized cut geometry with wider flutes and a coarser pitch designed specifically for soft metals like aluminum to prevent clogging.

While tungsten carbide is hard enough to cut steel, the 'Nf' geometry is too coarse for hard metals and may cause excessive chatter or tooth chipping. For steel, a Double Cut burr is recommended.

This burr features a standard 1/4-inch shank, making it compatible with most pneumatic and electric die grinders.

Standard double-cut or fine-cut burrs have small flutes that trap soft chips. You need an Aluminum Cut (or Non-Ferrous) burr like this Walter model, which has large open flutes to eject chips.

For a 1/2-inch diameter carbide burr, a speed range of 15,000 to 25,000 RPM is typically recommended for optimal material removal and control.

Yes, the open design of the Non-Ferrous cut also works well on hard plastics and wood, as it prevents the material from melting and sticking to the tool.

It leaves a relatively smooth finish for a roughing tool, but because it is a coarse pitch designed for removal, a secondary sanding or polishing step might be needed for a mirror finish.
