Semderm diamond drill bits are sourced from authorized US retailers and imported exclusively for you. They arrive factory-sealed, with all customs duties and GST included in the listed INR price. Delivery is via ExpressBox tracked shipping to your Indian pincode, ensuring you receive authentic tools. ### What materials can this diamond drill bit set cut? This 10-piece diamond hole saw set is designed for hard, brittle materials. It excels at cutting glass, ceramic tile, porcelain, marble, granite stone, and bottles. For best results and extended bit life, always use water for lubrication during drilling. ### Will the diamond hole saws fit my drill? These diamond drill bits feature straight shanks designed for compatibility with standard drill chucks. While specific shank sizes are not detailed, they are intended for use with common corded and cordless drills. Ensure your drill's chuck can securely grip the bit shank before use. ### How long will these diamond drill bits last? The diamond coating on upgraded carbon steel bits improves efficiency and durability. To maximize their lifespan, consistently add water during drilling for lubrication. This process not only extends bit life but also enhances the smoothness and accuracy of your cuts on hard surfaces. ### Are these diamond drill bits suitable for drilling through glass bottles? Yes, this diamond drill bit set is specifically designed for drilling through glass, including glass bottles. The diamond coating ensures a sharp, precise cut. Remember to use water for lubrication and cooling during the drilling process to prevent overheating and extend the bit's life. ### What is the difference between diamond and standard drill bits? Diamond drill bits have a cutting edge coated with diamond particles, making them exceptionally hard and ideal for drilling brittle materials like glass, tile, and stone. Standard drill bits, often made of high-speed steel, are suitable for softer materials like wood, plastic, and most metals. ## Compliance No product-specific compliance warnings identified.
