How to choose a drill bit?

There are over 200 models of hydraulic rock drills produced by companies such as Anbai Tuo, Sandvik, Montebet, Japan's Furukawa, and Finland's Doof, along with continuous product modifications, which should result in more than 400-500 types of drill bits.

How is the drill bit applied?

The drill rod is an important accessory of the rock drill and a key component of the drilling tool assembly. The drill rod cannot be used independently; it needs to be paired with a rock drill for application on drilling equipment. Drilling equipment is generally used for tunneling in underground mines.

What are the commonly used drill tail threads?

The thread forms of the drill rods include R22, R25, R28, R32, R38, T38, T45, T51, ST58, ST68, T60, EL60, and EL68. R threads are matched with hydraulic rock drills that have a lower impact power, while T threads are matched with hydraulic rock drills that have medium impact power.

Why are the performance and quality requirements for drill rods in the drill tool assembly the most stringent?

The drill rod is required to withstand the high-frequency impact power output by the hydraulic rock drill during the drilling work of the drilling tool set. It transmits the working energy to the drill bit to work on the rock through the rod body at the speed of stress waves.
