The ceramic diamond hollow drill bit, specially developed for the Bohle Aqua Drill wet drill, is designed for use on hard ceramic tiles, granite, marble and normal tiles.
The ceramic diamond drill bit has a ½" Belgian thread in knurled design, for quick change without tools on the Aqua Drill.
The feed rate is lower than with glass drills (approx. 25-50 % depending on the application)!
Application note:
Not suitable for glass (causes severe chipping when drilling in glass)!
