St. Bairui (圣佰锐) — factory-direct laser-welded diamond bridge saw blades engineered for high-volume granite & quartz slab processing.

Ultra-sharp, chip-free cutting — precision laser-cut diamond segments give a razor-sharp initial bite and clean edges with no chipping on granite and engineered stone.
Extra-long service life — premium diamond grit with a 15 mm ultra-high segment height for maximum usable cutting depth.
Industrial-grade 75Cr1 hardened core — high-carbon 75Cr1 steel, quenched & tempered and tensioned to eliminate wobble at high RPM.
Laser-deep welding — zero segment loss — deep laser fusion bonds every segment to the core, preventing segment loss / drop-off even in the toughest cuts.

Fits all common bridge saws and gantry (portal) cutting machines. Arbor bore: 50/60 mm.

For granite of all hardness levels — e.g. Black Galaxy (黑金沙), Sesame Black (芝麻黑), India Red (印度红) — plus quartz / engineered stone.
