This diamond drill bit is made in Italy with a high-quality diamond construction, ensuring that the bit will quickly drill numerous holes (40-60) in even the hardest porcelain, ceramic, and natural stone tiles (granite, marble, slate, and limestone). The bit is designed to be mounted on a standard 5/8" / 11 standard thread angle grinder without the use of an adapter (11,000 RPM recommended). Average drilling time of 20 seconds per hole! See the product video for operating instructions and tips.
