Analyzing the possible quality problems of rock drill bit will help manufacturers formulate improvement measures and prolong the service life of rock drill bit.

Proper use of button bits can improve engineering efficiency, extend service life and reduce maintenance costs.

Proper heat treatment is essential to ensure the strength, toughness and durability of threaded extension rods.

The common failure modes of mining tri-cone bits include bearing failure, cutting structure failure, cone shell wear, and gauge structure damage.

Heat treatment is an important process in the manufacturing and production of rock drilling tools, which plays a decisive role in improving their inherent quality and service life.

The correct use and grinding of button bits is an important means to improve engineering efficiency, and also a key measure to extend their service life.

To deal with the failure modes of button bit cemented carbide, we need to start from many aspects such as wear, heat treatment, and fracture of various parts.

By analyzing cemented carbide of button bit failure modes, the performance and service life of the button bit can be effectively improved.

Reasonable use of roller cone bit can start from the type of drill bit, the inspection of drill bit, and the precautions when drilling.

A tri-cone bit is comprised of 20+ distinct components, such as the cutting structure, bearing structure, locking element, oil storage sealing device, and nozzle device.

The roller cone bit can adapt to a variety of formations and is the most widely used drill bit.

This article mainly describes how to choose rock drilling cemented carbide grades for you through impact rock drilling and oil drilling cemented carbides.

This article mainly describes the development of rock drill bits for hydraulic rock drill jumbos, including button bits for tunneling jumbos, open-cutting drill jumbos and mining jumbos.
