With the Bosch x-lock pro Dry Speed diamond core cutter, you drill cleanly and quickly through hard ceramic tiles, wall tiles, and porcelain stoneware without any water cooling. Vacuum-brazed diamond grit ensures fast cutting performance and an extended lifespan during demanding bathroom installations and renovation projects. Featuring a 40 mm diameter and a 35 mm working length, it lets you create precise feed-through holes for pipes and fittings without cracking expensive tiles. Thanks to the keyless x-lock mounting system, you can snap the core cutter securely onto your angle grinder in seconds without using additional tools.
