Wet/Dry
Angle Grinder
Patterned Diamond
The ZENESIS™ OBSIDIAN diamond core bit is the ultimate tool for tile and stone,
capable of
drilling clean holes in porcelain, granite, marble, ceramic, DEKTON®, and quartzite—wet or dry.
Exclusive ZENESIS™ pattern diamond segments offer up to 70% longer life, while drop segments add
durability and weld protection. Depth gauge lines at 20mm and 30mm improve precision, and brazed
diamonds inside and out prevent binding for easy plug removal. Compatible with all grinders and
polishers.
Drills Engineered Stone, All Natural Stone, and Quartzite.
