Ingco 4.5" Ultra-Thin Diamond Disc | 115mm Turbo Rim Super-Thin Blade for Ceramic and Porcelain Tile (DMD031151HT)

The Ingco DMD031151HT Ultra-Thin Diamond Disc is a premium, industrial-grade rotary cutting wheel engineered for lightning-fast, chip-free slitting of hard ceramic, dense porcelain, and polished vitrified tiles. Specially designed to meet the rigorous demands of professional tilers and masonry contractors, this performance blade maximizes cutting efficiency while minimizing material wastage and micro-cracking along finished edges.

The blade features a super-thin 1.2mm turbo cutting rim profile, which reduces cutting friction and heat buildup during continuous operations. The matrix rim is embedded with high-concentration, industrial-grade diamond grit bonded in a specialized metal alloy matrix, ensuring long-lasting edge sharpness and uniform wear. To maintain structural stability under high rotational speeds, the core steel plate is reinforced with an inner structural flange layout that resists flexing, warping, and wobbling, guaranteeing perfectly square cuts. Additionally, the disc is engineered with integrated cooling ventilation holes that promote rapid airflow to dissipate heat, making it equally effective for dry or wet cutting applications when mounted on standard 115mm (4.5") angle grinders.
