Laser Welded Wet Diamond Core Bit for General Concrete Drilling

This professional-grade drill bit is designed for wet drilling. It must be continuously cooled with water during operation. The water flow not only protects the diamond drill bit from overheating and burning, but also reduces dust and flushes out concrete slurry. Dry drilling without water will cause the drill bit to fail and the substrate to anneal within

Absolutely. Our drill bits use high-concentration diamond and tough cobalt-based binder tips, combined with worm gear or crown gear designs, giving them excellent cutting power. They can cut through medium-diameter reinforcing steel at high speeds without chipping or breaking teeth, greatly reducing the risk of jamming. For extremely high-density or extra-thick reinforcing steel, it is recommended to reduce the rotation speed and maintain a high water flow.

Thanks to laser welding technology and an optimized diamond formula, our wet drill bits have a 35%-50% longer lifespan than ordinary high-frequency welded drill bits on the market under standard working conditions. For example, a best-selling 108mm diameter model can drill approximately 120-180 holes (300mm deep) in C30 concrete. The actual lifespan depends on the amount of reinforcing steel, the operating technique, and the water flow rate.

We offer globally mainstream standard threads. Please confirm your drilling rig's spindle thread before purchasing: 1-1/4"-7 UNC: The most universally used standard globally, M22 Fine Thread: Commonly found in some European and light-to-medium-sized drilling rigs. 1/2" BSP Pipe Thread: Mostly used in small core drilling machines. If you are unsure, please send a photo of your machine's spindle to our customer se
