The Refractory Diamond Blade is a professional tool designed specifically for cutting high-hardness refractory materials such as firebricks, ceramic fiber boards, silicon carbide, and calcium silicate boards. Featuring premium-grade synthetic diamond (SDA series) abrasives and high-temperature-resistant metal bonds (cobalt/nickel-based), this blade ensures efficient cutting, extended lifespan, and minimal wear. Ideal for dry or wet cutting, it is widely used in metallurgy, construction, and kiln maintenance industries.
