13K604 - 6-Inch Stringer Bead Wire Wheel 5/8-11 Hub

The Welder's Choice for Root Pass Cleaning

When you are welding pipe or structural steel, the quality of your prep work determines the quality of your weld. The Walter 13K604 6" Stringer Bead Wire Wheel is built specifically for the professional welder who needs a tool that works as hard as they do. Often referred to as a "pipeline brush," this wheel features a narrow, aggressive face designed to dig deep into the bevels and toes of your welds. It effectively rips out stubborn slag, silica islands, and heavy scale from the root pass (stringer bead) and hot passes, ensuring a clean surface for subsequent layers.

Safety and comfort are major concerns when using high-speed angle grinders. We know that a cheap, unbalanced wire wheel can turn a grinder into a vibrating jackhammer, leading to hand fatigue and loss of control. Walter has solved this by ensuring every 13K604 wheel is perfectly balanced before it leaves the factory. This means the wheel spins true, giving you a smooth run that lets you focus on the job, not on fighting your tool. The knot-twisted steel wire is tightly wound to resist flaring and breakage, providing a longer life and safer operation than standard crimped brushes.

Ready to work right out of the box, this wheel features a 5/8"-11 threaded hub that spins directly onto your 4.5-inch, 5-inch, or 6-inch grinder spindle—no searching for nuts or adapters. Whether you are cleaning up after a stick weld, prepping a joint for MIG, or removing rust from a repair patch, this stringer bead brush delivers the bite you need. It is an essential accessory for any welder's kit, providing the durability to withstand the heat and abuse of daily industrial use. Note: This brush is for use on carbon steel; use a stainless steel version for stainless projects to prevent contamination.
