Ceramic Glass Cross Drill Set

5-piece set of cemented carbide drill bits for ceramic tiles, glass, marble and thin metal — sizes 3 mm, 4 mm, 5 mm, 6 mm and 8 mm; lengths range from 73 mm to 78 mm depending on diameter; total net weight 125 g. Manufactured using YG6X tungsten carbide alloy and finished with an oxynitriding process to boost tip durability. The cross-angle cutting profile ensures low-resistance penetration, minimal vibration, and clean, burr-free holes without cracking or chipping at the surface. Ideal for accurate drilling in glazed ceramics, porcelain stoneware, mirrors, annealed glass and thin iron plates — always use water or coolant for optimal performance and bit longevity. Fits any drill with a minimum 10 mm chuck capacity.
