Key features

Laser welding creates a stronger bond between the diamond segments and steel body, providing higher safety and longer service life compared with conventional welding methods.

Premium diamond segments ensure smooth drilling performance and high cutting efficiency, even when drilling through reinforced concrete with steel rebar.

Optimized diamond concentration and segment formula reduce wear and extend tool lifespan, lowering operating costs for professional users.

The precision-engineered steel tube minimizes vibration and improves drilling accuracy.

Compatible with most professional core drilling machines: 1-1/4" UNC M22 1/2 BSP
