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.

Moreover, the use of extension rods significantly enhances worker safetymining rock extension rod. By enabling operators to work farther away from the face of the rock, there's less risk of injury from falling debris or rock bursts. Additionally, the precision afforded by these rods means that blasting can be more accurately targeted, further minimizing hazards associated with explosive use.

Finally, the supply chain disruptions caused by the COVID-19 pandemic have also contributed to the price increase of the Jack Hammer. Factories that produce power tools may have been forced to shut down or operate at reduced capacity due to lockdowns and other restrictions. This has led to a decrease in the supply of Jack Hammers, which in turn has driven up prices as consumers compete for a limited number of available units.
