INTEGRATED SINK CORE BIT 3-1/4"

This 3-1/4" Integrated Sink Core Bit is engineered specifically for fabricators creating drain openings and flange grooves in countertops with integrated sinks made from the same material as the surface. Perfect for quartz, granite, marble, quartzite, and porcelain, this diamond core bit delivers a clean, precise cut required for modern seamless sink installations.

Designed to core out the sink drain opening and simultaneously prepare the recess needed for stainless-steel strainers or garbage disposal flanges, this bit ensures accuracy, clean edges, and professional-grade results. Whether you're fabricating high-end custom kitchens or matching factory-finished integrated sinks, this tool guarantees the correct geometry for perfect fitment every time.
