13B280 - Walter 8-Inch Knotted Twist Bench Grinder Wire Wheel with Bushings

Premium Industrial Wire Wheel for Bench Grinders

The Walter 13B280 8-Inch Knotted Twist Bench Grinder Brush is engineered for professionals who demand reliability and performance in their surface finishing operations. In the world of industrial abrasives, balance is everything. An unbalanced wheel causes excessive vibration, which not only leads to poor surface finish and operator fatigue but can also prematurely destroy the bearings of your expensive bench grinding machinery. Walter Surface Technologies has addressed this by crafting these brushes with superior industrial-grade wire that is precision-balanced to ensure smooth, concentric rotation even at operating speeds.

This specific model features a knotted twist design. Unlike crimped wire brushes which are better suited for light surface cleaning, the knotted construction provides a rigid, high-impact action. This makes it the tool of choice for aggressive applications such as stripping heavy rust, removing multiple layers of paint, cleaning weld scale, and deburring jagged steel edges. The wire tips strike the surface with force, effectively dislodging contaminants without gouging the base material when used correctly.

Versatility is a key component of the 13B280's design. Every shop has different equipment, and finding the right arbor size can often be a hassle. Walter solves this by including a set of nested reducer bushings with every wheel. While the core arbor is 1 inch, these high-quality bushings allow the wheel to fit securely on 3/4-inch, 5/8-inch, and 1/2-inch shafts. This universal compatibility ensures that whether you are equipping a heavy-duty industrial pedestal grinder or a standard workshop bench grinder, this brush is ready to perform immediately out of the box.

For maintenance and repair operations (MRO), fabrication shops, and metalworking facilities, the Walter 8-inch Knotted Twist Brush offers an extended lifespan and consistent performance, reducing the frequency of wheel changeovers and increasing overall shop productivity.
