Generally, we divide core bits into two main welding methods : High frequency weldingand Laser welding .

High frequency welding

Laser welding

High frequency welding core bit :The price is cheap, and the sharpness and service life are not as high as those of laser welding. But the segment can be welded repeatedly.When encountering high-strength reinforced concrete, the core bit may break.

Laser welding core bit :Long lifespan, very sharp, and not easy to lose segment,Stable structure and not easily damaged. But the price is higher than that of high-frequency welding, and it cannot be welded (the customer does not have a laser welding machine locally)

3 type core bit ( Shibuya type )

Integrated wet core bit and embedded thread (A-rod)

Dry core bit
