• Vacuum Brazed Technology
Diamond grits are permanently bonded to high-strength steel using vacuum brazing, ensuring 3x longer lifespan vs. electroplated bits.
Even diamond distribution minimizes heat buildup for smoother cuts and zero material chipping.
• Universal 5/8"-11 Connector
Compatible with standard drills, grinders, and rigs for seamless switching between tasks.
• Wet/Dry Dual Mode
Use with water cooling for dust-free operation on tiles/stone or dry drilling for quick fixes on glass/ceramics.
• Glass & Ceramic Artistry
Drill flawless holes in stained glass, mosaic tiles, or laboratory equipment without cracks.
• Industrial Maintenance
Repair machinery components requiring precise bore sizes (Φ8-Φ6) in composite materials or engineered ceramics.
• Complete Size Range: Covers 6–50 mm for 90% of drilling needs.
• High ROI: Durable vacuum brazing reduces replacement costs.
• Global Compliance: Meets ISO 9001/CE standards for safety and performance.

Vacuum brazed is a process that uses high temperature and low pressure in a vacuum environment to braze. In the vacuum environment, due to the low pressure, the gas will not cause oxidation, hydrogenation or nitriding reactions, so it can be welded with high melting point and difficult to process materials, such as alloy steel, tungsten, molybdenum and so on. Vacuum brazing, because it does not use flux, significantly improves the corrosion resistance of the product, eliminates all kinds of pollution and pollution-free treatment equipment costs, and has good safety production conditions.
