Premium 30CrMo Steel Core
The foundation of a precision cut is a stable core. We source our steel blanks from China’s largest and most reputable ISO9002-certified steel disc factory. Made from high-toughness 30CrMo steel with strict tolerances for flatness and side run-out (+21μm /H8/H7), the core eliminates wobbling and deflection during deep cuts. We also offer Normal, Low Noise, and Silent core options for urban construction zones with noise restrictions.
