08B507 - Walter HP 5-Inch Spin-On Grinding Wheel 1/8 Thick

High-Performance Abrasive for Industrial Applications

The Walter 08B507 HP™ Grinding Wheel represents a pinnacle in abrasive technology, designed specifically for industrial environments where efficiency and durability are paramount. This 5-inch Type 27 depressed center wheel is engineered with Walter's proprietary high-performance bonding matrix, which ensures a high removal rate while maintaining an impressive lifespan. Unlike standard grinding wheels that may glaze over or degrade rapidly under heavy load, the HP series is formulated to fracture and self-sharpen, providing consistent cutting action from the first spark to the hub.

One of the defining characteristics of this specific SKU is its 1/8-inch thickness. While standard grinding wheels are typically 1/4-inch thick, the reduced profile of the 08B507 makes it exceptionally versatile. It is robust enough for general surface grinding and shaping but thin enough to perform effective notching and root pass cleaning in multi-pass welding applications. This duality allows fabricators to utilize a single wheel for multiple stages of surface preparation and finishing, thereby streamlining inventory and reducing tool changes.

Operational efficiency is further enhanced by the integrated 5/8"-11 threaded arbor. This "Spin-On" system eliminates the need for a separate flange nut and pin wrench, allowing operators to mount or dismount the wheel by hand in seconds. This feature not only reduces downtime but also minimizes the risk of wheel slippage and vibration, resulting in a safer and smoother grinding experience. Rated for a maximum speed of 12,200 RPM, this wheel is compatible with most standard 5-inch angle grinders and is optimized for use on steel and cast iron.

Technical Specifications and Usage

The Walter HP wheel utilizes a premium aluminum oxide grain structure (A-24-HP) that is specifically tempered for hardness and toughness. This ensures that the grain withstands the high pressures of heavy grinding without premature dulling. The wheel is reinforced with high-tensile fiberglass mesh to ensure structural integrity and safety during operation. It is an ideal choice for MRO (Maintenance, Repair, and Operations) professionals, structural steel fabricators, and heavy equipment manufacturers who demand reliability and performance.
