Vacuum Brazed Diamond Drill&Mill Bit for Ceramic/Porcelain/Stone

This product series comprises vacuum-brazed diamond drill and mill bits designed for combined drilling and grinding operations on ceramic, porcelain, stone, marble, and granite. The range includes multiple models (JD865205014, JD865255014, JD865355014, JD865505014, JD865685014, JD865755011, JD865205025, JD865255025, JD6702010105, etc.) with diameters ranging from 20mm to 75mm (including variable-diameter options like 10-35mm and 20-50mm). Key specifications include a drilling diamond height of 5mm, grinding diamond heights of 25mm-30mm, lengths of 60mm-92mm, and versatile shank types such as M14, 5/8″-11 threads, triangle shanks, and Weldon shanks (with symmetrical flat rectangular tangs for secure clamping).

a. Product Features and Advantages:

• Vacuum Brazing Process: Ensures diamond particles are firmly bonded to the steel matrix via vacuum brazing, enhancing cutting efficiency, wear resistance, and service life.
• Dual-Function Design: Integrates drilling and grinding capabilities in one tool, eliminating the need for bit changes during composite processing.
• High-Density Diamond Particles: Features numerous small, sparkling brazed diamond grits (visible as dense coatings on the bit face and body), providing sharp cutting edges for hard materials.
• Versatile Specifications: Offers a wide range of diameters (20mm-75mm, including 10-35mm/20-50mm variable sizes), lengths (60mm-92mm), and shank types (M14, 5/8″-11 threads, triangle shanks, Weldon shanks with anti-slip tangs) to suit diverse equipment and depth requirements.
• Ergonomic Shank Stability: Weldon shanks (with symmetrical flat rectangular tangs) and triangle shanks ensure secure clamping in drill chucks, preventing slippage and enabling efficient power transmission.
• Intuitive Identification: A distinct blue band encircling the midsection aids in quick model/spec recognition during use.

b. Product Applications:

Ideal for combined drilling and grinding of hard materials including ceramic tile, porcelain tile, marble, granite, and natural stone. Suitable for construction, renovation, and stone processing scenarios requiring efficient, multi-functional cutting solutions.
