Zenesis Black 4 Bridge Saw Blade – 14 in., 25 mm Segment
Zenesis Black 4 Bridge Saw Blade – 14 in., 25 mm Segment
The Zenesis Black 4 Bridge Saw Blade is a 14 in. wet-cut bridge saw blade with 25 mm segments, hybrid diamond layering and patterned diamond placement, built for long life cutting granite and engineered stone on a bridge saw.
Zenesis positions the Black 4 as its longest-lasting bridge saw blade: the patterned placement keeps diamond exposure consistent from the first cut to the last, so cutting speed does not fall off as the segment wears down. It is the blade for a shop whose saw runs granite and quartz all day and wants the fewest blade changes. The 25 mm segment is the tallest in the Zenesis range; for mitered edges, the Zenesis Miter Bridge Saw Blade – 14 in. with its short 10 mm segment tracks straighter under side load.
