12B004 - Walter HP 4-Inch Concrete Grinding Cup Wheel with 5/8-11 Hub

Heavy-Duty Concrete Grinding with Walter HP Series

The Walter 12B004 HP Cup Wheel is a premium abrasive tool designed specifically for the rigorous demands of concrete and masonry fabrication. Part of Walter's High Performance (HP) series, this 4-inch cup wheel is engineered to deliver aggressive material removal rates while maintaining exceptional durability. It is the ideal solution for professionals who require consistency and speed when leveling concrete surfaces, removing form marks, or smoothing rough masonry edges. The wheel utilizes a specialized silicon carbide abrasive grain structure that resists loading and maintains a sharp cutting face throughout its lifespan, ensuring that productivity remains high from the first pass to the last.

Safety is a paramount concern in grinding operations, particularly with cup wheels that undergo significant stress. Walter has addressed this by incorporating a steel-backed hub design. This steel backing wraps around the base of the wheel, providing superior structural integrity and preventing wheel breakage under heavy loads. This design feature significantly enhances operator safety compared to standard unreinforced cup wheels. Furthermore, the wheel is precision-balanced during manufacturing to eliminate vibration. Reduced vibration not only protects the angle grinder's bearings but also drastically reduces operator fatigue, allowing for longer periods of work with greater precision and control.

Efficiency in tool changeovers is critical for maintaining workflow in industrial environments. The 12B004 features Walter's signature Spin-On mounting system with an integrated 5/8"-11 threaded arbor. This allows the user to mount and dismount the wheel by hand in seconds, eliminating the need for pin wrenches or flange nuts that can easily be lost or damaged. This seamless integration of safety, performance, and convenience makes the Walter HP Cup Wheel a top-tier choice for construction, renovation, and masonry professionals seeking reliable and effective grinding solutions.
