Bosch Drill Bit Tile 4mm

This Bosch 4mm 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 bit “wandering”.
