The Rubi flap disc Diamant Lamellenschijf is a 125 mm diameter abrasive disc with 50/60 grit designed for intensive grinding and sanding applications on hard materials. This flap disc features a coarse grit composition that enables rapid material removal, edge profiling, and surface preparation on fully vitrified ceramic tiles and natural stone. With its M14 threaded connection, this disc is compatible with standard angle grinders and operates effectively at the recommended speed of 9650 revolutions per minute. The 50/60 grit specification provides aggressive abrasion for tasks such as roughening surfaces, creating beveled edges, and removing excess material from tile and stone workpieces. This tool is engineered for professional use in construction and tile setting applications where efficient material removal and edge work are required. The flap disc construction allows for consistent performance across the working surface, maintaining cutting efficiency throughout the disc's lifespan. Measuring 125 mm in diameter, this disc provides optimal coverage for various surface preparation tasks while maintaining manageable control during operation. The diamond abrasive composition ensures durability when working with hard ceramic and stone materials that typically wear down conventional abrasives quickly. This product is suitable for preparing surfaces for further finishing work, creating custom tile shapes, and processing edges on stone and ceramic installations. The M14 thread connection provides secure mounting on compatible angle grinding equipment, ensuring stable operation during demanding applications. Operating at 9650 rpm delivers optimal cutting performance while maintaining user control over the grinding process. This flap disc is designed for tradespeople and professionals who require reliable performance in material removal and surface preparation tasks on challenging substrates.
