- The insertion technique varies depending on the type of rock bit being used. For instance, PDC bits require a more controlled insertion due to their sensitivity to shock and vibration, while roller cone bits, with their self-sharpening properties, can withstand higher levels of impact.
- Top hammer bits are designed to endure the high impact and vibration caused by the hammer hitting the bit while drilling. They are made of high-quality materials such as tungsten carbide, which provides excellent wear resistance and durability. The design of the top hammer bit also plays a significant role in determining the drilling speed and accuracy.
- In addition to reach and depth, drill bit extension rods also offer increased stability and control during drilling
- In addition to their versatility, button tooth bits are also known for their long service life and cost-effectiveness
button tooth bit. The hardened steel buttons are designed to resist wear and abrasion, resulting in extended bit life and reduced maintenance costs. This durability makes button tooth bits a cost-effective solution for drilling operations that require frequent bit changes.

Sinochem International and Shanghai Research Institute of Chemical Industry Co., Ltd. (Shanghai Chemical Institute) jointly established the “Sinochem – Shanghai Chemical Institute Composite Materials joint laboratory” in Shanghai Zhangjiang Hi-Tech Park.



Inspired by the flexibility and rigidity of natural spider silks webs, a research team led by Prof. YU Shuhong from the University of Science and Technology of China (USTC) developed a simple and general method to fabricate superelastic and fatigue resistant hard carbon aerogels with nanofibrous network structure by using resorcinol-formaldehyde resin as a hard carbon source.

grating profiles cover an expansive range that covers requirements of the coal and iron ore industries, wine and beverage manufacturing, plant access walkways and heel-safe pedestrian access walkways to the current standards.
