08P705 - Walter Xcavator 7-Inch Heavy Duty Grinding Wheel 5/8-11 Spin-On

Product Overview

The Walter Surface Technologies 08P705 Xcavator is a premium 7-inch grinding wheel engineered for the most demanding industrial applications. Designed with a focus on heavy metal removal, this Type 27 depressed center wheel utilizes an enriched Zirconium grain structure that delivers aggressive cutting action while maintaining exceptional wheel life. The 1/4-inch thickness provides the rigidity and durability required for heavy weld removal, beveling, and chamfering on substantial workpieces. This specific model features an integrated 5/8-11 threaded hub (Spin-On), which ensures perfect centering on the grinder spindle, reduces vibration, and allows for tool-free wheel changes, thereby increasing operational efficiency and safety.

Technical Performance

The Xcavator line is distinguished by its ability to maintain a high removal rate (MRR) throughout the life of the wheel. Unlike standard aluminum oxide wheels that may glaze over or lose aggression as they wear, the Xcavator's advanced bonding matrix fractures the abrasive grains in a controlled manner, constantly exposing new, sharp cutting edges. This self-sharpening action is critical for maintaining throughput in high-volume fabrication environments. The wheel is rated for a maximum speed of 8,600 RPM, making it compatible with standard 7-inch angle grinders. It is manufactured to be Fe-S-Cl free (Iron, Sulfur, and Chlorine free), making it safe for use on stainless steel without risk of cross-contamination or corrosion induction.

Safety and Ergonomics

Operator safety and comfort are paramount in the design of the 08P705. The integrated hub system not only simplifies mounting but also significantly reduces wheel vibration compared to non-hubbed wheels used with backing flanges. Reduced vibration leads to lower risk of White Finger Syndrome (HAVS) and allows operators to work for longer periods with less fatigue. The wheel's construction is reinforced to withstand the lateral forces typical of heavy grinding, meeting or exceeding strict safety standards. For MRO professionals and fabrication managers, the Walter Xcavator represents a cost-effective solution by reducing the total cost of grinding through faster cycle times and fewer wheel changes.
