Hengshui Jrain Frp drilling rod spirals down into the earth.

The 'hex shank' refers to the shape of the bit's shaft, which is hexagonal rather than cylindrical. This design was primarily introduced to address the common issue of drill bits slipping in the drill chuck. The hex shank provides a more secure grip, reducing slippage and ensuring better control during drilling operations. It also allows for quick and easy changes without requiring a key, saving valuable time on the job.

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.
