OVERVIEW

Aggressive Cleaning for Pipe Welders

When you are laying down root passes on a pipe, you need a tool that can get into the bevel and rip out slag without hesitation. The Walter 13L454 Stringer Bead Brush is built exactly for that purpose. With a narrow 1/4-inch face width, this brush is designed to fit perfectly into tight grooves and V-grooves, ensuring that every bit of slag and silica is removed before your hot pass. This prevents inclusions and ensures your welds pass X-ray inspection every time.

The secret to this brush's performance is the .020-inch twist knot steel wire. Unlike crimped wire that is soft and flexible, these knotted wires act like tiny hammers, impacting the surface to break away heavy scale and spatter instantly. The wires are heat-treated and oil-tempered to resist fatigue, meaning they won't fly out prematurely even under the stress of high-RPM grinders. Rated for up to 20,000 RPM, this brush allows you to run your grinder at full speed for maximum cleaning efficiency.

Comfort is just as important as speed when you are welding all day. An unbalanced wheel makes a grinder shake, leading to numb hands and fatigue. Walter creates these brushes with individual knot balancing, ensuring smooth operation. This allows you to maintain precise control over the grinder, preventing the brush from jumping out of the groove and damaging the bevel walls. Upgrade your loadout with a brush that works as hard as you do.

FAQ

A stringer bead brush has a very narrow face width (usually 1/4 inch) designed specifically to fit into the narrow grooves and bevels of pipe welds to clean the root pass.

This brush comes with a 5/8"-11 threaded arbor, which is the standard spindle size for most 4-1/2" and 5" angle grinders in North America.

No, this brush uses carbon steel wire. Using it on stainless steel will cause cross-contamination and lead to rust. You should use a stainless steel (304/316) wire brush for stainless applications.

The Walter 13L454 is rated for a maximum speed of 20,000 RPM, allowing it to be used safely on high-speed angle grinders.

Twist knot brushes are much more aggressive and rigid. They are designed for heavy-duty cleaning and impact action, whereas crimped brushes are for lighter surface cleaning and paint removal.

Yes, the 4-1/2 inch diameter and 5/8-11 arbor make it perfectly compatible with standard 4-1/2 inch angle grinders.

The .020 inch measurement refers to the diameter of the individual wire filaments. Thicker wires like .020 are stiffer and more aggressive than thinner wires like .014.
