This 12mm Rubi Dry Cut Diamond Drill Bit is sized for small to medium installations requiring slightly larger clearances than standard fixings.

The 12mm size is particularly useful for installations where fittings require comfortable clearance without stepping up to the larger drill bit sizes, making it an essential addition to any professional tiler's toolkit.
