10 Steel Drill Bits for Tile, Glass, Ceramic, Marble and Mirror, 6mm, Tungsten Carbide Tip for Hard and Fragile Materials

【ALLOY STEEL MATERIAL】: This set of drill bits is forged from premium quality alloy steel. These glass drill bits allow for smooth and precise drilling in ceramic tiles, marble, mirrors, glass, aluminum, concrete, and wood. The durable drill bit should be well lubricated for best results. This is most often done by running water over the drilling surface. 【DIMENSIONS】: Designed with a 6mm pointed tip, these multi-material drill bits have a 1/4-inch design that reduces breakage. Length: 70mm. Our spear-head drill bits are very durable and built to last. 【APPLICATION】: Ideal for drilling ceramic tiles, glass, marble, and mirrors. When drilling hard materials, please use water for lubrication; proper cooling can prolong the drill bit's lifespan. Glass drill bits are generally used with electric drills to create holes in all the materials mentioned. [TUNGSTENE CARBIDE TIP]: The ceramic drill bit features a tungsten carbide tip for greater efficiency and a longer lifespan. During the drilling process, the coating rubs against the glass, creating a perfect hole in the material being drilled.
