7 Pcs Diamond Drill Bit Set, Hex Shank 5/6/8/10/12mm Dry Drilling Bits, Multi-Functional Tile Hole Saw, for Ceramic, Porcelain, Marble, Granite and Glass

WHAT YOU GET: This set includes 7 drill bits in a storage bag — 6 diamond-coated dry drilling bits in sizes 5mm, 6mm, 8mm, 10mm and 12mm, plus one 6mm masonry drill bit for pilot holes. A practical kit that covers most common drilling needs for home and workshop use. DURABLE DIAMOND COATING: These tile drill bits are made from carbon steel bonded with diamond powder through a vacuum-brazed process. The dense, sharp diamond particles provide strong wear resistance, so the bits stay sharp longer and won't snap or chip when tackling hard surfaces. DRY DRILLING WITH BUILT-IN WAX: These drill bits come with an integrated cooling wax that activates during use. As you drill, the wax melts to lubricate and cool the bit, minimising debris and preventing overheating. This allows you to work dry — no water, no mess, and less clean-up. PRECISE START WITH PILOT BIT: The included 6mm masonry drill bit works as a pilot to create a starter hole, helping the diamond bits stay on track without slipping or wandering. This gives you more accurate positioning and cleaner holes, especially on smooth, glazed tile surfaces. VERSATILE USE: These masonry drill bits are suitable for a wide range of materials, including porcelain tiles, granite, marble, stone, concrete, glass, and plastics. Whether you're a tradesperson on site or a DIYer tackling a bathroom or kitchen renovation, this set covers the job.
