The Milwaukee M14 Diamond Max Tile Drill Set (4 pieces, SKU 4932471863) is engineered for dry drilling in extremely hard surfaces such as porcelain, gres, quarry tiles, marble, stone, cast iron, and fiberglass. Each bit features a premium diamond bond, a robust alloy body that resists bending, and multiple access slots for easy removal of the core (slug). The M14 thread enables direct mounting onto angle grinders or via adapters for polishers or straight grinders. These bits produce clean, precise holes without edge scratching, and require no cooling or water—making them efficient and practical for challenging tile drilling tasks.
