Vacuum Brazed Diamond Flume Drill Bit for Ceramic/Porcelain/Stone

This product series comprises vacuum brazed diamond flume drill bits specifically engineered for creating precise holes in ceramic, porcelain, and stone materials such as water tanks and components requiring stepped holes. The range includes multiple models (JD8662401560, JD8662451560, JD8662651560, JD8662701560) with a consistent diamond height of 15mm, overall length of 60mm, and M14 5/8″-11 thread for tool attachment. Cutting diameter ranges vary per model (40-60mm to 50-70mm), catering to versatile application in stepped hole drilling and hard material processing.

a. Product Features and Advantages:

• Vacuum Brazing Process: Ensures strong bonding of diamond grains to the drill bit matrix, enhancing durability and delivering efficient cutting performance for hard materials.
• Specialized Design for Stepped Holes: Tailored for drilling water tanks and components requiring stepped holes, with a rough-textured diamond-embedded segment (grayish-white, top) and a circular flange (middle) both coated with diamond particles for enhanced grip and precision.
• Dual-Diamond-Coated Structure: Features a diamond segment at the top (for initial penetration) and a diamond-covered flange around the middle (for stability during drilling), improving cutting accuracy and reducing material chipping.
• Standardized Parameters: Maintains uniform diamond height (15mm), overall length (60mm), and M14 5/8″-11 thread across models, ensuring compatibility with common drilling equipment.
• Versatile Model Range: Offers four models with distinct cutting diameter ranges (40-60mm, 45-60mm, 45-65mm, 50-70mm) to suit varying hole size requirements in general and specialized applications.
• Ergonomic Physical Design: Cylindrical black main body with clear size/thread indication (e.g., “40MM M14” at the base) for easy identification and handling.

b. Product Applications:

Ideal for drilling precise holes in a variety of hard materials including ceramic tiles, porcelain slabs, stone surfaces, and water tank components. Specifically suited for creating stepped holes and general-purpose drilling in renovation, plumbing, and stone processing scenarios.
