SDS-Max Rotary Hammer Core Bit

For hard rocks, the optimal impact speed is 5-7.5m/s. If it is too low, the drilling speed will be low and the unit power consumption will increase; if Carbon Metal Hole Saw is too high, Carbon Metal Hole Saw will not only increase the unit power consumption, but also cause pistons and drill bits. The fatigue failure. Therefore, when the impact energy, impact frequency and piston weight are the same, the slender piston is beneficial to slow down the fatigue damage of the piston and the drill bit, the effect of damaging the rock is good, and the unit power consumption is small. Therefore, the impactor should adopt a rod-hammer-shaped slender piston structure.  

The greater the impact power, the higher the impact frequency, and the greater the impact power, but the greater the impact power, the drilling efficiency is not necessarily high. Therefore, the impactor is mostly a type of impactor with large impact power and low impact frequency.
The drill bit is a tool that transmits impact energy and directly breaks the rock
