D02 Series – Vacuum Brazed Diamond Core Drill Bits
Precision Drilling for Stone, Ceramic & More
In today’s construction and renovation industry, efficiency and precision are paramount. The D02 Series Vacuum Brazed Diamond Core Drill Bits are specifically engineered to meet the demands of drilling into hard materials like granite, marble, and ceramic. With advanced manufacturing technology, superior durability, and broad compatibility, the D02 series stands out as the professional’s choice.
Advanced Vacuum Brazed Technology
The D02 series utilizes vacuum brazing, a state-of-the-art process where industrial-grade diamond particles are permanently fused to the steel body under high temperature and vacuum. This results in:
Exceptional sharpness
Superior wear resistance
Longer tool life
Efficient cutting with minimal chipping
Compared to electroplated or sintered drill bits, vacuum brazed tools maintain consistent performance even in the most demanding tasks.
Complete Size Range to Suit Every Job
The D02 series offers a comprehensive size range from 20mm to 150mm in diameter, all with a:
Total length of 60mm
Working length of 40mm
Cutting edge width of 15mm
Universal connection: M14 or 5/8"-11 UNC thread (compatible with angle grinders and handheld drills)
All models are clearly labeled with a D02 prefix (e.g., D02T0220, D02T0250, D02T2100), ensuring easy identification and ordering.
Widely Applicable for Various Materials
Whether you're working in interior decoration or outdoor installations, the D02 drill bits are perfect for:
