Vacuum Brazed Diamond Back Bolt Drill Bit for Stone

This product series comprises vacuum-brazed diamond back bolt drill bits for stone, designed for drilling and enlarging hard materials in construction and stone processing applications. The range includes the model JD869970420 with specific dimensions (diameter 9.7mm, diamond height 4mm, work length 20mm, overall length 48mm) and a thread specification of M14, catering to precise drilling needs in stone-related projects.

a. Product Features and Advantages:

• Vacuum Brazing Process: Ensures firm bonding of diamond grains to the drill bit matrix, enhancing durability and cutting efficiency for prolonged service life.
• High-Quality Diamond Grains: Features a cluster of rough diamond particles brazed at the tip, providing strong cutting force and wear resistance for effective drilling through hard materials.
• Hexagonal Body Design: Adopts a hexagonal-shaped main body (golden-bronze color) for easy gripping and stable connection to drilling equipment, reducing slippage during operation.
• Bolt Connection Part: Extends from the hexagonal body as a secure attachment point for tools, ensuring reliable integration with drilling machinery.
• Standardized Specifications: Clear dimensional markings (Art. No. JD869970420, 9.7mm dia., 4mm diamond height, 20/48mm work/overall length, M14 thread) for easy identification and equipment compatibility.
• Efficient Precision Cutting: Engineered for stone-drilling applications, enabling accurate and smooth hole creation with minimal material damage.

b. Product Applications:

Ideal for drilling and enlarging a variety of hard materials including granite, marble, concrete, and ceramics. Widely used for external support installations in curtain wall projects, as well as general stone processing scenarios requiring efficient and precise hole drilling.
