OVERVIEW

Maximize Industrial Productivity with Walter HP XX

The Walter HP XX 9" x 1/8" x 7/8" Grinding Wheel (SKU: 08H902) represents the pinnacle of abrasive technology for heavy-duty industrial applications. Designed for fabrication shops and industrial environments where time is money, the HP XX series is engineered to deliver the lowest total cost of grinding. By combining the latest advancements in grain technology with a proprietary bonding system, Walter has created a wheel that not only removes material faster than competitors but also lasts significantly longer, reducing the frequency of wheel changes and downtime.

This specific 9-inch model is tailored for large-scale surface grinding on steel. Its 1/8-inch thickness provides the rigidity required for aggressive stock removal while maintaining the structural integrity needed for safety at high rotational speeds. The Type 27 depressed center design allows for a comfortable grinding angle (typically 15 to 30 degrees), making it ideal for smoothing welds, beveling plates, and general heavy fabrication work. The 7/8-inch arbor ensures compatibility with standard large angle grinders found in MRO and construction settings.

Safety and performance go hand-in-hand with the HP XX. The wheel is reinforced to withstand the rigors of heavy lateral pressure, ensuring operator safety during the most demanding tasks. For facility managers and procurement specialists, choosing the 08H902 means investing in a consumable that optimizes labor efficiency. The high removal rate translates to fewer man-hours per project, while the extended lifespan reduces inventory turnover and waste. Whether you are working on structural steel, pipelines, or heavy machinery, the Walter HP XX stands as the superior choice for cost-effective grinding.

Key Industrial Benefits

FAQ

The Walter 08H902 HP XX grinding wheel is specifically formulated for use on steel. It provides aggressive removal rates and long life on carbon steel and structural steel applications.

This grinding wheel features a standard 7/8-inch arbor hole, making it compatible with most industrial 9-inch angle grinders that use a locking nut.

The maximum safe operating speed for the Walter 08H902 9-inch grinding wheel is typically 6,600 RPM. Always verify the RPM rating printed on the wheel matches or exceeds your tool's speed.

While it can grind stainless steel, the HP XX formulation is optimized for mild/carbon steel. For stainless steel, Walter offers specific formulations (like HP Stainless) to prevent contamination and ensure optimal performance.

Type 27 refers to the shape of the wheel, which has a depressed center. This geometry allows the locking nut to sit recessed, permitting grinding at a 15 to 30-degree angle without the mounting hardware interfering with the workpiece.

The HP XX series is Walter's premium line, offering significantly higher material removal rates and longer lifespan compared to standard general-purpose wheels, resulting in lower overall project costs.

No, this is a 1/8-inch thick Type 27 grinding wheel designed for surface grinding and stock removal. It should not be used for cutting (cutoff) operations; use a Type 1 or Type 27 cutting wheel for that purpose.

No, this is a bonded abrasive grinding wheel and does not require a backing pad. It mounts directly to the grinder using the appropriate flanges and nut.
