Excalibur 4-inch Rigid Disk

The Excalibur 4-inch Rigid Disk is a compact diamond grinding disc built for precise floor prep in tight quarters. It mounts on hand-held grinders with a hook-and-loop backing and handles both wet and dry operation, enabling controlled material removal in edges, corners, and other hard-to-reach areas. The rigid disk design maintains constant contact for a consistent, uniform finish on concrete, engineered stone, and other dense substrates.

Features & Specifications

• Diameter & Center Hole: 4 inches in diameter with a 5/8 inch center hole to fit standard hand-held grinder spindles; hook-and-loop backing for quick mounting.
• Backing & Attachment: Hook-and-Loop backing provides fast mounting and easy removal on compatible hand-held grinders, minimizing downtime between passes.
• Operation & Use Case: Designed for both wet and dry grinding applications; ideal for detail work, edges, and tight spaces where larger machines cannot reach.
• Material Compatibility: Suitable for concrete, engineered stone, glass, granite, marble, terrazzo, limestone, travertine, and other dense substrates.
• Design & Performance: Rigid disk construction maintains consistent contact with the substrate for even material removal and a smooth, uniform finish across passes.
• Equipment Compatibility: Specifically designed for use with hand-held grinders using a hook-and-loop disc system, enabling controlled, close-quarters grinding on small-diameter tools.
