With the Carat EHSB012000 tile drill bit, you easily drill clean 12 mm holes into hard ceramic tiles, porcelain stoneware, and natural stone without water cooling. Thanks to the M14 female thread connection, you mount the bit directly onto your angle grinder to start working immediately without extra adaptors. The built-in wax core melts during operation to provide continuous cooling and lubrication. With a length of 30 mm, you achieve neat, chip-free mounting holes for plumbing and bathroom accessories on any jobsite without a water supply.
