The New Way of Drilling Tiles
EXPERT HEX-9 Hard Ceramic Drill Bit for Long Life Drilling Hard Tiles

Frequently asked questions
It depends on several parameters, e.g the drill bit’s diameter, the pressure applied, rpm, drilling direction and thickness and hardness of your tile. With 6 mm-diameter CYL-9 Soft Ceramic drill bit, you can get 50+ holes in soft ceramic tiles. With EXPERT HEX-9 Hard Ceramic drill bit, you can drill 10+ holes in hard ceramic tiles*, and 100+ holes in soft ceramic tiles.
The tile’s size and price are good indicators. Tiles which are 30x30 cm large and larger are normally hard. The Mohs scale and PEI rating is often used to indicate the material’s hardness, with PEI ranging from 1 for low wear resistance to 5 for high wear resistance. Hard ceramic tiles normally cost more than the soft ones.
