11° Taper 38mm 5 Teeth Button Bit With Spring Controlled Ball Teeth For Rock Drilling
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.
