Silicon Carbide Fibre Discs Depressed Centres

SAIT Silicon Carbide Fibre Discs are specially developed for grinding, sanding, and finishing stone and marble surfaces. OUR ORIGINAL SOLUTION FOR STONE Originally introduced in 1953, these fibre discs remain a trusted choice for professional stoneworkers worldwide. Manufactured with a full resin-bonded construction, they provide excellent durability, consistent cutting performance, and long service life. The depressed centre design maximises abrasive coverage and helps maintain disc stability during use. Available in grit sizes from 36 to 400, these discs cover everything from aggressive stock removal to fine finishing and surface preparation. Suitable for natural stone, marble, engineered stone, and similar hard materials. 🛠️ Full Resin-Bonded Fibre Disc Construction The durable resin-bonded design delivers excellent strength and wear resistance. Manufactured to comply with EN13743 safety standards for reliable professional performance. The robust construction ensures consistent results throughout the disc's working life. 💎 Premium Silicon Carbide Abrasive Grain Silicon carbide is one of the hardest abrasive materials available. Its sharp cutting edges provide fast material removal and efficient grinding performance. The abrasive grain continually fractures during use, exposing fresh cutting edges. This self-sharpening action helps maintain cutting speed and extends disc effectiveness. 🎯 Optimised for Stone and Marble Designed specifically for stoneworking applications, these discs excel on marble, granite, limestone, and engineered stone. The hardness of stone materials promotes controlled grain fracture, maximising abrasive performance. This results in efficient stock removal and a consistent surface finish. ⚙️ Depressed Centre Design The depressed centre increases the usable abrasive surface area. This design helps reduce deformation during operation and improves disc stability. Greater abrasive coverage means improved efficiency and longer working life. 🔄 Closed Coat Abrasive Technology The closed coat construction provides approximately 90–95% abrasive coverage. This maximises cutting performance on hard materials such as stone and marble. The dense abrasive layer produces a more uniform scratch pattern and improved surface appearance. 📏 Available Sizes and Specifications Disc Diameter: 180 mm Bore Size: 22 mm Grit Range: 36, 50, 60, 80, 120, 180, 220, 320, 400 Construction: Full Resin Bonded Fibre Disc Abrasive Material: Silicon Carbide Compliance: EN13743 🚀 Applications Ideal for: Stone grinding Marble finishing Surface preparation Edge refinement Scratch removal Sanding natural stone Finishing engineered stone Restoration and refurbishment work Metal Applications Non-ferrous metals, Stainless steels Building Materials Applications Marbles, Building Materials ✅ Why Choose SAIT Stone Fibre Discs?
