The Bosch 5 Piece Ceramic Tile Drill Bit Set is a specialist drilling set designed for clean, accurate holes in soft ceramic tiles without the need for lubrication or cooling. Built around the CYL-9 Soft Ceramic drill bit, this set is engineered for professional tilers and contractors who need reliable performance when fixing fixtures, fittings, and accessories to tiled surfaces. The sharply ground tip bites into the tile surface immediately, preventing skating and ensuring precise hole placement from the first moment of contact. The cylindrical shank is compatible with standard three-jaw drill chucks, making this set straightforward to use with most corded and cordless drills. For best results, always use in rotary mode only at low speed — no hammer action required. This five-piece set covers the most commonly needed fixing diameters, making it a practical addition to any tiler's toolkit.
