【Multiple Applications】 Perfect for porcelain, glass brick, ceramic, ceramic tiles, granite, marble, quartz, limestone, fiberglass terrazzo, masonry, quartz stone, and sandstone.

【Reasonable Size】 Thanks to the sharp and extremely hard diamonds, the diamond core drill bit ensures clean and fast professional drilling. The high-quality industrial diamonds provide a fast cutting speed.

【High Quality】 Thanks to the sintered diamond segment and maximum precision, the cup drill bit has a long service life.

Sintering allows for high fracture toughness, making the diamond material less susceptible to impacts. It exhibits particularly high strength and heat dissipation, which extends its service life. Furthermore, the cup wheel is high-quality, temperature-resistant, and reduces vibration.
