08P510 - Walter Xcavator 5-Inch Heavy Duty Grinding Wheel Type 27

Technical Overview of the Walter Xcavator Grinding Wheel

The Walter Surface Technologies Xcavator (SKU: 08P510) represents a significant advancement in abrasive technology, specifically engineered for high-demand industrial environments. This 5-inch Type 27 depressed center wheel is formulated with a Zirconia Alumina grain structure (Spec: ZA-16-P), designed to deliver the highest possible removal rates on ferrous metals. It is particularly effective on challenging materials such as tungsten carbide, quenched steel, and tempered steel, where standard aluminum oxide wheels often glaze or fail prematurely.

A defining technical feature of the Xcavator series is the integration of Comfort Max™ Technology within the wheel hub. This design innovation actively dampens vibration at the source, reducing the transmission of harmonic resonance to the angle grinder and the operator's hands. By mitigating vibration, the wheel not only reduces the risk of Hand-Arm Vibration Syndrome (HAVS) during prolonged use but also ensures a more consistent contact patch with the workpiece, leading to uniform material removal.

With dimensions of 5" x 1/4" x 7/8", this wheel is compatible with standard industrial angle grinders. The 1/4-inch thickness provides the structural integrity required for heavy beveling, weld removal, and edge shaping. The ZA-16 grit is ultra-coarse, prioritizing speed and aggression over surface finish, making it the optimal choice for the initial stages of fabrication where bulk material removal is the critical metric.
