Walter 2-3/8 Inch Mounted Steel Cup Brush for Die Grinders

Tough Brushes for Hardworking Welders

When you're in the middle of a job, you need tools that don't quit. The Walter 13C018 2-3/8" Mounted Cup Brush is built to handle the grit and grime of the welding shop. We know that surface preparation is half the battle in getting a good weld, and this brush is designed to strip away contaminants fast so you can get to the arc. Made with durable carbon steel wire, it bites into rust, slag, and old paint, leaving you with clean metal ready for fabrication.

This isn't your average hardware store brush. Walter makes abrasives that last, meaning you spend less time changing out worn-out brushes and more time working. The 13C018 is designed to mount easily into your die grinder or drill, giving you the power of a cup brush in a compact package. It's perfect for those tight spots where a 4-1/2" grinder just won't fit—like inside corners, around small fixtures, or on tubular steel. The wire is tough enough to clean thoroughly but flexible enough to handle contours without digging in.

Vibration can kill your hands after a long day, but Walter's balanced design keeps this brush running smooth. That means better control for you and less chatter on the workpiece. Whether you are cleaning up a repair job, prepping a railing for paint, or scrubbing down a casting, this mounted cup brush delivers the performance you expect from a top-tier brand. Add the Walter 13C018 to your toolbox and experience the difference quality makes.
