Drill Bit Test Lab

Direct, continuous footage shows Zhonghuan drill bits at work. Use each record to review cutting behavior, compare head architectures and shortlist samples for your own substrate program.

Field demonstration

Continuous drilling footage gives buyers a direct view of the product, substrate, centering, tracking and debris movement during the cut.

Internal comparative test

Side-by-side result with a documented comparator and setup.

Controlled test report

Repeatable method, measured results, sample count, and limitations.
