5-inch Aluminum Backplate for Diamond Abrasives

This 5-inch aluminum backplate provides a rigid mounting platform for Velcro-backed diamond pads on 5/8"-11 arbors, delivering a balanced combination of material removal and maneuverability for granite, marble, and concrete. Constructed from solid aluminum, it offers rigidity and corrosion resistance while remaining lighter than steel, enhancing productivity on large-area floor projects and in tight spaces such as countertops. It attaches directly to most common angle grinders for quick pad changes and reliable performance across grinding, honing, and polishing tasks.

Features & Specifications

• 5/8"-11 Thread Pattern: Attaches to most common angle grinders for direct mounting on standard arbors, enabling straightforward tool integration on job sites.
• Hook & Loop Surface: Velcro-backed diamond pads and sanding discs secure quickly and release readily for efficient pad changes during multi-step projects.
• Material & Construction: Solid aluminum backing plate provides rigidity and corrosion resistance while remaining lighter than steel, reducing user fatigue and improving grinding control.
• Size & Geometry: 5-inch (approximately 127 mm) diameter optimized for efficient material removal while maintaining control in confined spaces like countertops.
• Applications & Compatibility: Designed for diamond polishing pads and other Velcro-backed discs on granite, marble, and concrete surfaces; compatible with most 5/8"-11 arbors on common angle grinders.
• Operational Advantage: Provides a stable platform for consistent pad rotation, enabling smoother grinding, honing, and polishing with reduced wobble and improved post-use vacuum recovery.
