Engineered for creating small, precise holes in hard tiles, this 5 mm diamond core drill is ideal for installing wall plugs, anchors, and pilot holes. Its vacuum-brazed diamond tip provides a durable cutting edge, while the M14 thread ensures a direct, secure connection to an angle grinder. Many of these bits contain an internal wax coolant for efficient dry drilling, which reduces heat and clears debris to prolong the tool's life. This design ensures rapid, chip-free drilling for a professional finish.
