This Bosch CYL-9 ceramic drill bit is also suitable for drilling porcelain, non-toughened glass, and all soft- to medium-density tiles.
This porcelain tile drill bit has a reinforced head with a cutter made of highly durable carbide, which provides good wear-resistance and ensures a very long bit lifetime. This glass drill also has a centring tip which ensures a precise start to drilling, with no drill bit “wandering”.
The Bosch CYL-9 ceramic range used to be called the “Expert for Ceramic” range. This new drill bit for porcelain tiles, glass, and ceramics does not require coolant, which makes them much easier and cleaner to work with. They must still be used at low speeds and without impact.
