Diamond-Cut Hole Saw Drill Bit, High-Performance Hole Cutter for Glass/Tile/Granite/Marble (100mm)

Diamond Drill Bits: Made of carbon steel with a diamond-coated surface, they are suitable for materials such as porcelain, glass, marble, ceramic, stone, and granite. High-Quality Drill Bits: Their thick, brazed inserts offer a long service life, ideal for drilling clean, precise holes and cutting perfect circles. Long Lifespan: Robust and durable, these drill bits offer superior performance; their lifespan is more than 8 times longer than ordinary diamond drill bits. Note: When drilling, start at a 45-degree angle, make a crescent-shaped pilot hole, and then drill vertically to prevent the bit from slipping. Never let the drill bit dry out; keep it moist and cool with water. Our Commitment: We are committed to creating premium products designed to enhance the comfort and safety of our customers. Our professional quality control team takes care of every detail that matters to you. Product Description Features: Material: Carbon Steel. Drill bit diameter: 10 mm. Diamond coating thickness: 1.5 mm. Features: This diamond drill bit allows you to drill a complete circle in glass, tile, marble, granite, ceramic, and other materials. Precautions: Always use water to lubricate the drill bit; otherwise, it may overheat and burn. Compatible with standard electric drills. Make a semi-circular mark at a 45° angle, then hold the drill bit vertically. Reducing the drilling speed and pressure, and increasing the water flow to cool the hole saw, will significantly extend the drill bit's lifespan.
