6-130mm M14 Dry Vacuum Brazed Diamond Hole Saw

Product Overview

Our M14 Green Cyclone Vacuum Brazed Diamond Core Drill Bits are professional-grade drilling tools specifically engineered for precise, efficient drilling in hard materials. Made with premium diamond particles and steel substrates, these bits come with a standard M14 thread that fits most M14 angle grinders seamlessly. This ensures stable installation and straightforward operation, making them suitable for both professional tradespeople and DIY hobbyists alike.
Offered in 36 precise sizes spanning from 6mm to 130mm, this series meets all drilling requirements for home renovation and industrial projects. Each bit boasts an overall height of 60mm, with a 10mm diamond working layer—an optimized design that guarantees consistent drilling depth and durable performance. The striking green coating not only boosts corrosion resistance but also facilitates quick identification amid the hustle and bustle of job sites.

The core advantage lies in the advanced vacuum brazing technology adopted, which forms an ultra-strong bond between the diamond particles and the steel body. Industry-validated data confirms that this technology extends the service life by 3 to 5 times compared to traditional electroplated bits, substantially lowering replacement costs. Featuring a unique cyclone-shaped cutting head and high diamond exposure rate, the bits enable faster, more powerful drilling while reducing heat generation and material chipping, ensuring clean, burr-free holes on every occasion.

A standout feature is their dry drilling capability, eliminating the need for water cooling. For smaller sizes (6mm-12mm), an integrated wax core provides automatic cooling during operation, preventing overheating and prolonging tool life. These bits are perfect for drilling precise holes in ceramic tiles, granite, marble, natural stone, pebbles, and concrete walls. They serve as a cost-effective and time-saving solution for tiling, plumbing, and masonry projects.

Each package contains one high-quality diamond core bit. Please note that slight size deviations (1-3mm) may arise due to manual measurement, and color variations might occur due to lighting conditions during photography.
