Our Brazed Flat Grinding Disc for Sintered Stone is a professional multi-purpose abrasive tool designed specially for sintered stone slab processing. Manufactured in our integrated metal material factory, it adopts stable vacuum brazing technology to firmly combine high-quality diamond grit and high-strength steel substrate. Available in three mainstream sizes 105mm(4"), 115mm(4.5"), 125mm(5") with universal 22.23mm center hole and 30mm wide abrasive surface, it perfectly matches all standard angle grinders worldwide. One disc completes cutting, edge chamfering and fine surface grinding, greatly simplifying stone construction work.

Why Choose Our Brazed Flat Grinding Disc
Self-owned metal material factory strength
Unlike middlemen outsourcing cheap steel blanks, we produce steel substrates and brazing powder in-house. Our rigid base avoids vibration and deformation during grinding, a common defect of thin inferior competitor discs.
30mm wide abrasive layer & solid vacuum brazing & Eco-friendly 
The extended 30mm working area improves processing efficiency and uniform wear. Vacuum brazing firmly fixes diamond grit to prevent shedding. Low-cost rivals adopt narrow segments and weak bonding, leading to fast abrasion.
Exclusive formula for anti-chipping sintered stone. Our high-temperature vacuum brazing ensures tight adhesion with no toxic volatiles. 
Optimized diamond layout minimizes edge cracks on fragile expensive sintered slabs, while ordinary discs easily chip materials and raise your project waste cost.
3-in-1 multi-functional design saves tool budget
It finishes cutting, chamfering and polishing with one disc, replacing separate single-purpose wheels to lower repeated procurement cost and speed up construction.
Full-size universal compatibility
105mm(4")/115mm(4.5")/125mm(5") sizes with standard 22.23mm bore fit global angle grinders without adapters, while most competitors lack complete size options.
Flexible OEM wholesale service
We support custom logo, adjusted diamond concentration and bulk discounts for importers and stone plants.
