Video Description:
We tested it—see the highlights and what to expect in real operation. In this video, we demonstrate the Henglong 38mm 5-tooth button bit with spring-controlled ball teeth and 11° taper connection during actual rock drilling applications. Watch as we showcase its performance in granite and hard rock conditions, explain how the spring-locked tooth design reduces fractures under heavy impact, and highlight the quick coupling system for efficient bit changes on-site.
