What our customers say…

"Following instructions and drilling porcelain tiles while running water over them was a success, the resulting holes were perfect and effortless to achieve. Secret is let the diamond drill do the work while you concentrate on the position. I comfortably used a variable speed cordless drill which in turn improved safety when working with water. The diamond core bits were easy to use, good quality chrome so no rust, easy to remove the cut tile from the core bit and with a little care will last from one job to the next. Excellent!" Rupert Hammond

"Results were impressive for boring through porcelain tiles. All holes being perfect, no chipping. The bits sailed through the tiles no problem only took a couple of minutes and the job was done." John (Monafissel)
