Weiler 13131v Knot Wire Wheel 4 Inches Stringer Bead

Product Description

The WEILER 13131v is a 4-inch stringer bead knot wire wheel designed for demanding weld cleaning and surface preparation work on angle grinders. The wheel uses 0.020-inch steel fill wire twisted into 32 knots, delivering concentrated wire-tip contact that cuts through weld scale, slag, and surface oxides efficiently. A 5/8 inch-11 UNC arbor nut provides secure mounting on standard right-angle grinders. Rated to 20,000 RPM, this wheel is built for high-speed grinder applications common in fabrication shops and field welding environments. It meets ANSI B165.1 standards and is RoHS compliant. Installation and surface prep professionals in structural and pipe welding will find this wheel suited to consistent, repeatable passes on root welds and prep work.

This wheel is used primarily in metal fabrication settings for cleaning root pass welds, interpass weld cleaning, and general surface preparation ahead of coating or inspection. The stringer bead profile concentrates wire contact into a narrow face width of 3/16 inch, making it effective for working inside tight weld joints and grooves. The 7/8-inch trim length provides wire flexion appropriate for contour work without excessive flare. This product is vending machine ready, making it well suited for tool crib and managed inventory programs on industrial job sites.

Installation Notes

Installation should be performed by a qualified operator following the grinder and wheel manufacturer safety guidelines. Confirm the grinder RPM rating meets or exceeds the wheel rating before mounting. Always inspect the wheel for damage before use and ensure the arbor nut is properly torqued per grinder manufacturer specifications. Operators must wear appropriate PPE including face shield, gloves, and hearing protection when running wire wheels at high speed.
