Cutting clean holes in porcelain, granite or engineered stone is hard work with ordinary drill bits, and one chipped tile can be costly to replace. This 10-piece diamond drill bit set has vacuum brazed diamond cutting edges designed for fast, smooth drilling in hard materials. It includes hole saws from 6 to 68 mm, a milling bit and a chamfer bit, covering most plumbing, electrical and renovation jobs. All pieces are stored in an EVA case for easy transport.

Each bit uses an M14 thread, suiting angle grinders and other M14 threaded tools. The 10 mm milling bit lets you enlarge or shape openings, and the 50 mm chamfer bit tidies hole edges for a neat, finished look. A 10 mm diamond height on the cutting edge gives working life across many holes. The set is suitable for ceramic tile, porcelain, granite, marble, quartz and engineered stone.

Key Features:

• Vacuum Brazed Diamond – Fast cutting and clean hole finishes on hard materials.
• Seven Hole Sizes – 6, 8, 10, 25, 35, 50 and 68 mm.

How to Use:

• Screw the required bit onto your M14 angle grinder or tool, using the adapter where needed.
• Mark the hole and start at a slight angle to cut a guide groove before bringing the bit upright.
• Keep the bit cool with water and let the diamond do the work without forcing it.
• Finish the edge with the chamfer bit, then clean and dry the bits before storing.
