【High Quality Materials】Our diamond metal drill bits for glass are made from high quality alloy, with a built-in surface coating to prevent rust and provide faster cutting, making it easier to drill the hard enamel of tiles. They are characterized by high heat resistance, high efficiency, wear resistance and long service life.

【Cooling Wax】Dry diamond drill bits are filled with a wax lubricant inside, suitable for dry and wet drilling. When dry drilling, the wax melts and cools the cutting surface, or you can use water for additional cooling during wet drilling, thus extending the life of the ceramic drill bit.

To drill efficiently and beautifully, it is necessary to replace the blue bit after using the yellow drill bit in order to extend the life of the drill bits and improve efficiency.
