Thin-wall diamond core bits for drilling ultra-compact sintered stone and large-format porcelain — Dekton, Lapitec, Neolith, Laminam — and ceramic floor and wall tile. A 2 mm rim drills fast and leaves smooth, chip-free holes in material from 6 mm to 30 mm thick. Two versions: 5/8-11 thread for grinders and drills, and 1/2" gas thread for CNC machines.
