08X900 - Walter Xcavator XX 9-Inch Ceramic Grinding Wheel

Technical Overview: Walter Xcavator XX 08X900

The Walter Xcavator XX (SKU: 08X900) represents the pinnacle of heavy-duty abrasive technology, specifically engineered for industrial environments requiring rapid stock removal on high-tensile alloys. This 9-inch grinding wheel features a proprietary blend of ceramic grains. Unlike conventional aluminum oxide abrasives which dull and glaze over time, ceramic grains are engineered with a micro-crystalline structure that allows them to fracture under pressure. This controlled fracturing process continuously exposes new, sharp cutting edges, maintaining a consistent cut rate (MRR) throughout the lifespan of the wheel.

Designed with a Type 27 depressed center profile, the 08X900 is optimized for a 30-degree grinding angle, providing rigidity and stability during aggressive material removal. The wheel measures 9 inches in diameter with a 1/4-inch thickness and a standard 7/8-inch arbor, making it compatible with most heavy-duty industrial angle grinders. A critical specification for this product is its Fe-Free formulation. The bond matrix is manufactured to contain less than 0.1% Iron (Fe), Sulfur (S), and Chlorine (Cl). This ensures that the wheel does not introduce contaminants into the workpiece, a vital requirement when working with stainless steel in nuclear, pharmaceutical, or food-processing applications where corrosion resistance is paramount.

The bond system of the Xcavator XX is reinforced to withstand the high torque and centrifugal forces associated with 9-inch grinders running at speeds up to 6,600 RPM. The wheel's density is calibrated to balance longevity with aggression, preventing the premature shedding of grain while ensuring the wheel does not load up on softer metals. It is particularly effective on hard metals, including hardened steel and various grades of stainless steel, where thermal management is critical to prevent heat discoloration or warping of the base material.
