We bring together measured drilling reports and continuous footage of our drill bits at work. Review the test conditions, results and head architectures to shortlist samples for your own substrate program.
Watch our ZHMAX-168 SDS-Max six-cutter in a close-up stone-drilling test. The edited 22.5-second clip shows the drill body, penetration and debris discharge. Send your substrate and required hole size for a matched sample test.
Zhonghuan's profiled 2-cutter architecture, drilled on camera in hard granite. One shaped carbide tip forms two cutting edges and a centering point: it starts where you put it, tracks straight, and keeps the bore clear.
ZHMAX-7 puts the hammer's energy behind one primary blade instead of splitting it across four symmetrical wings. The primary blade drives the fracture, the two side cutters open the bore to diameter, and the open head geometry gives the cuttings a clear path to the flutes.
Send the product family, geometry, diameter, substrate, and comparison target. We can structure samples and evidence under a dedicated test topic.
