I7 geometry compared with the earlier flat 2-cutter head
Zhonghuan's internal product-development benchmark compared the I7 profile with our earlier basic flat 2-cutter architecture. The approximate gains provide a design reference; request a matched sample evaluation for your substrate, hammer energy, diameter and drilling depth.
Continuous in-cut footage
The uninterrupted in-cut view follows the Zhonghuan SDS-Max 28 mm 2-Cutter I7 Drill Bit through continuous dry hammer drilling in a pink granite-like natural stone block. Centering, straight tracking and dust movement around the flutes can be reviewed throughout the working sequence.
