Hengshui Jrain Frp pdc anchor shank drill bit

Performance metrics such as impact energy, rotation speed, and feed force are critical determinants of a drill’s efficacy. High-impact energy ensures that the tool can break through hard rock effectively, while a variable rotation speed allows operators to adapt to different drilling conditions. The feed force determines how much pressure the drill can apply to the rock face, affecting penetration rates and drill bit longevity.
