Porcelain Tile Drill Bit Tile Max Drill Bits have a newly designed and unique "P95" precision tip which has been diamond ground from the best quality tungsten. This enables the user to drill through a wide range of materials such as: PEI 5 Class Porcelain, Ceramics, Fine Stoneware, Marble, Concrete, Engineering brick and even Granite! The asymmetric drill design reduces resistance by 25% ensuring that there is no wandering on start of drilling, there is also less chance of cracking or chipping (dependant on tile type) which leads to a perfectly formed round hole. The low stress, high temperature brazing method used to attach the tip to the shank, ensures that it remains attached under the most extreme drilling conditions. The deep and wide fluting is able to cope with the maximum amount of spoil removal. The ingenious triangular shaped shank guarantees no slip rotation in the drill machines chuck. Due to the tips unique self renewing design, after frequent use on the hardest materials, the drill can be then used on softer substrates. Recommendations: The drill bit works best on low revolution speeds and its life will increase when used with water to cool the tip down. The drill bit should only be used on the rotary setting and must not be used on the hammer setting.
