08H705 - Walter HP XX 7-Inch Hubbed Grinding Wheel Type 27

Premium Heavy-Duty Grinding Performance

The Walter HP XX 7" x 1/4" x 5/8-11" Grinding Wheel (SKU: 08H705) represents the pinnacle of abrasive technology for heavy-duty steel applications. Designed for industrial environments where efficiency and safety are paramount, the HP XX series utilizes a proprietary bonding matrix that secures the abrasive grain for maximum cutting duration while allowing for controlled breakdown to expose fresh cutting edges. This balance ensures that the wheel maintains a high material removal rate (MRR) without glazing, even under the intense pressure of structural fabrication.

This specific model features a Type 27 depressed center profile, the industry standard for aggressive grinding angles between 15 and 30 degrees. The 1/4-inch thickness provides the necessary rigidity to withstand lateral forces and heavy loads, making it ideal for beveling, weld removal, and smoothing rough flame-cut edges. The inclusion of the integrated 5/8-11 Spin-On hub is a critical feature for operational efficiency; it ensures the wheel is automatically centered every time, significantly reducing vibration compared to standard non-hubbed wheels. This reduction in vibration not only improves surface finish but also helps mitigate the risk of Hand-Arm Vibration Syndrome (HAVS) for operators using the tool over extended periods.

Safety and compliance are core to Walter Surface Technologies' engineering. The HP XX is reinforced to exceed safety standards, providing peace of mind in high-speed grinding operations up to 8,600 RPM. By integrating the mounting hardware directly into the wheel, the risk of using mismatched or damaged flanges is eliminated. For MRO managers and procurement specialists, the 08H705 offers a compelling value proposition: although the initial unit cost may be higher than generic alternatives, the extended lifespan and reduced changeover time result in a significantly lower total cost of grinding per foot of weld.
