Diamax 4″ Cyclone Resin Cup Wheel with Aluminum Backer

The Diamax 4″ Cyclone Resin Cup Wheel with Aluminum Backer is a professional-grade, ultra-aggressive grinding tool engineered for maximum material removal and rapid surface preparation on natural and engineered stone surfaces, including granite, marble, quartz, and engineered stone. Designed for heavy-duty fabrication and installation tasks, this cup wheel combines high-performance resin-bond diamond abrasives with a sturdy aluminum backer, providing exceptional stability, precision, and control during aggressive grinding operations.

Ideal for professional stone fabricators, countertop installers, and tile contractors, this cup wheel excels at heavy stock removal, surface leveling, edge shaping, and rough profiling. Its robust construction ensures consistent performance under demanding conditions, making it perfect for dry grinding applications where precision and speed are required.

The aluminum backer provides rigidity and heat dissipation, reducing vibration and improving operator control while maintaining smooth, consistent contact with the stone surface. Its 4″ diameter is ideal for both detailed edge work and larger surface areas, allowing operators to reach corners, curves, and tight spaces that require precise material removal.

Engineered for use with angle grinders and air polishers, the Cyclone Resin Cup Wheel delivers high cutting efficiency, fast stock removal, and extended tool life. The resin-bond diamond composition ensures even wear, reliable performance, and minimal chipping, helping professionals achieve flat, level surfaces and prepare stone efficiently for subsequent polishing stages.

Key Features & Specifications

Bond / Construction

Premium resin-bond diamond abrasive molded into a heavy-duty cup wheel design with a lightweight aluminum backer for strength, balance, and extended tool life.

Attachment / Mounting

Designed for secure mounting on standard angle grinders, ensuring stable operation and precise control during extreme grinding and surface preparation.

Intended Use

Engineered for ultra-coarse dry grinding of granite, marble, quartz, and engineered stone surfaces. Optimized for dry use to remove heavy material and prepare surfaces for subsequent grinding and polishing stages.

Grinding / Finish Design

30 grit provides maximum cutting aggression to eliminate deep damage, flatten severely uneven surfaces, and rough-form stone prior to finer grit processing.

Stability & Control

Cup wheel profile combined with an aluminum backer minimizes vibration and improves balance, allowing smoother grinding and better operator control during heavy-duty use.

Max RPM

Rated for high-speed operation (RPM dependent on machine specifications) to support efficient grinding and consistent surface results.

Applicable Tools

Compatible with angle grinders and hand-held grinding tools designed for resin-bond diamond cup wheels.

Ideal Applications

Countertops, vanity tops, stair treads, floor edges, and decorative stone surfaces requiring extreme dry grinding, heavy stock removal, and aggressive surface leveling.
