Tile Drill Bit Set, Diamond Drill Bit for Stoneware with 5, 6, 8, 10, 12 mm Diameters, 6 mm Metal Drill Bit for Tiles, Ceramic Drill Bits for Glass, Granite, Marble, Quartz, and Hard Materials

【Multiple Diameters】In addition to 5, 6, 8, 10, and 12 mm tile drill bits, you will receive a 6 mm carbide drill bit. This eliminates the need for a diamond drill bit, allowing you to drill holes even more precisely and easily. 【Unique Dry Drilling Design】With wax inside for cooling, our diamond-tipped drill bits have integrated wax cores that automatically absorb and dissipate heat as you drill. Dry drilling eliminates water and reduces pollution. 【Multiple Uses】This porcelain stoneware drill bit is ideal for drilling clean holes in hard materials, including tiles, porcelain, granite, ceramics, glass, mirrors, stone, and brick. Note: Not for wood, metal, or plastic. 【Compatible Round Shanks】These glass drill bits are designed with a round shank, compatible with most power tools, such as hand drills, angle grinders, and bench drills. The side flutes help remove debris and drill holes smoothly and quickly; the depth gauge is also useful for precise projects. 【High-Quality Materials】This drill bit set with vacuum-brazed diamond technology offers high efficiency, faster cutting, and longer life. The 6-piece dry diamond drill bit set includes 5, 6, 8, 10, 12 mm, and 6 mm carbide drill bits. Ideal for drilling clean holes in hard materials. High-quality diamond grit is heat-resistant for efficient drilling. Filled with cooling wax, suitable for dry drilling. No cooling is required during drilling, as the drill bits are equipped with cooling wax inside. However, this can increase the lifespan of the drill bits. How to use: 1. Install the drill bit on the hand drill for use. 2. The electric drill maintains a high speed and tilts at a 45° angle throughout the process to create the crescent-shaped groove. 3. After drilling the positioning groove, place the electric drill upright, slowly shake it in one direction, and drill. 4. Drilling complete. It is important to use a slight rotating motion while drilling! This ensures optimal drilling results. Note: Prohibited materials: cement, metal, tempered glass, wood, plastic, etc. If using a cordless drill, ensure the speed is above 1600 RPM. When using a hand drill, ensure the speed is above 2000-3000 RPM. Dry diamond drill bit set 5/6/8/10/12 mm, 6 mm carbide drill bits, drilling depth: ≤35 mm, length: 65 mm
