JESSIN ROCK DRILL CO.,LIMITED, www.dthhammer-js.com
PDC drill bits use PDCs as main cutting media, with the excellent wear-ability and impact toughness of the PDC. It has a long service life, high-efficiency, and good cost performance.
PDC bit is mainly used for drilling soft and medium hard rock, and it must work under low drilling pressure, mid-low speed and big drainage.
JESSIN can supply all kinds of PDC core and non-core bits, PDC sintering matrix bits and PDC anchor bits. PDC bit can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway.
We also can design PDC bits according to customer requirements, such as different geology conditions, special strata and so on.
Features
1. Super long service life. The service life of PDC bit is as much as 4~5 times than diamond bit, at least 10 times than tungsten carbide bit.
2. High drilling speed.
3. Can be operated with low pressure and speed.
4.Has a good gage protection.
5.Used widely, more suitable for drilling in the stratum with hardness coefficient f

M/M extension ROD
The round cross sections are more prevalent for extension drilling applications. A round rod has less material and thus is lighter to handle and less expensive than an equivalent size hexagonal rod. While hexagonal rod is particularly advantageous for drifting and tunneling drilling. The increased rigidity of hexagonal drill rods enables them to abating hole-deviation and enhances flushing for cleaning holes. Even with the larger cross section, hexagonal steel can still accommodate the same diameter bit as that of an equivalent round steel.
Carburization technique is mainly used in the production of big diameter rods to ensure excellent performance. Carburizing is for hardening entire rod to provide an external over entire rod surface area. Carburized steels are used primarily in underground applications and where water is used as a flushing medium. High Frequency technique is primarily used in the production of small diameter rods to reduce fragileness of drill steels. High Frequency is for hardening only the thread ends of the rod. This provides the longevity of the product as well as being more suitable for more drilling condition need. Steels produced with this technics primarily used in surface drilling applications where air is the primary flushing medium. Phosphorising is to improve anti-erosion capability of the entire external rod surface area.

The increased rigidity of hexagonal drill rods enables them to abating hole-deviation and enhances flushing for cleaning holes. Even with the larger cross section, hexagonal steel can still accommodate the same diameter bit as that of an equivalent round steel.
M/f rods provides tighter connections and is easier for handling and quicker for uncoupling than m/m rods, and are potential to drill straighter holes.
