Aluminum Oxide Mini Grinding Discs Type R 3" 36 Grit 25/Box - Gemtex Abrasives

The Gemtex Abrasives 21230305 Aluminum Oxide Mini Grinding Discs are engineered for demanding automotive and industrial applications, providing efficient material removal and consistent finishes. Built with a heavy-duty vulcanized fibre backing and a specialized bond coat, these discs resist loading, glazing, and grain stripping for extended performance. Designed for use with a rapid change system, they ensure quick and secure disc replacement during operation.

Key Features

• Durable Construction: Features a multilayer, heavy-duty vulcanized fibre backing for enhanced longevity and stability during aggressive grinding tasks.
• Optimized Abrasive Performance: Utilizes specially processed aluminum oxide abrasive grit, electronically applied for superior toughness, sharpness, and a strong bond to minimize premature grain stripping.
• Loading Resistance: A formulated bond coat actively resists loading and glazing, maintaining cutting efficiency throughout the disc's lifespan.
• Rapid Change System: Equipped with the common Type R nylon threaded male button, allowing for secure, tool-free disc changes with a simple half-turn.
• Professional-Grade Durability: Engineered to out-perform and out-last conventional 2-ply and 3-ply cloth-backed discs, reducing downtime and replacement costs.

Applications

These mini grinding discs are ideal for a range of tasks encountered by professional technicians and mechanics. Common uses include general metal grinding, deburring sharp edges, weld preparation and blending, rust and paint removal, and surface conditioning in fabrication shops or automotive repair settings. Their compact 3" diameter makes them particularly effective for accessing confined areas and intricate contours on vehicle components or machinery.
