Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications

This casing pipe tube is used for specific applications or when it's in the drilling hole. The W casing borrows from DCDMA C80 tubing and the DCDMA W thread form. With a straight thread, this general casing is suitable to various drilling fields where thread casing is required to be left in the ground.

The casing pipe tube joins to tapered tool joint with modified buttress thread. It is made from high-quality alloy mainly used in geotechnical and hammering applications.

Standard core barrel lengths are 1.5 and 3.0 metre. Core barrel is supplied with a blank reaming shell and thread protector. Core Bits purchased separately.

​T2 series core barrels are available in metric sizes 56 , 66, 76, 86, 101, 116 mm conventional core barrel.

T2 double tube core barrels are widely used and suitable for coring in all hard and soft formations, with water flushing and/or polymer fluid. The thin walls provide fast penetration, lower bit cost and larger core sample.

Roschen® Tricone Drill Bits are designed for the most severe rotary blasthole applications, yet are cost effective for a wide range of drilling needs. The new bit line includes six diameters ranging from 171 mm (6 ¾ in.) to 311 mm (12 ¼ in.). Their carbide shapes and cutting face arrangements are optimized for high wear resistance and improved rock fragmentation, and the aggressive, long-lasting cutting structure delivers a superior rate of penetration.

With the S.P.T Drill Rod tapered thread design and friction welded construction it provides maximum stiffness and a more rigid threaded joint coupled with reliability, durability and optimum field performance. The tube element is manufactured from cold drawn seamless steel tubing and the end pieces from heat treated alloy steel.

DTH drill pipes are widely used in mining,water well drilling,geothermal,oil and all kinds of DTH rock drilling,with high quality low carbon steel to ensure good resistance to strengthen and tensile,friction welded to ensure the adapter and pipe connect tightly as a whole set the cyclic extrusion-compression ensure reliable pipe

Drill Rod was designed for deep hole wire line applications, with its strong tool joints, and flexible mid body, it excels in directional drilling applications. Welded tool joints of specially heat treated steel with very high mechanical resistance. Superior welding process and weld inspection to ensure optimum concentricity.

The Friction Welded Drill Rod is uniformly normalized. The Drill Rods are stronger in strength, uniform in mechanical properties giving a longer life.

Rod handlers improve safety by keeping helpers away from energized components and potential injury from wrenches under power. Coring rod threads will jam in 20-30% of joint make-ups, meaning that time is lost, and 5% of the time the helper is back near the rotation unit, reducing safety. These jams add significant unproductive time either to unjam threads or rotate threads backward 100% of the time when manually making joints.

Wireline drill rods or named diamond drill rods are manufactured by CNC machines; in exploration diamond drilling, a diamond drill bit is attached to the end of wireline drill rods to cut a core.

BT drill rod is widely recognized and accepted genuine “Tuff” rod with the “T” thread. BT drill rod is known for strong pull back and performance in difficult drilling conditions. BT drill rod is perfectly suited when high pull back and torsion is needed in shallow or long, straight holes with no or little deviation.BT drill rod is available for application in standard DCDMA B size hole.

These are all manufactured to the strictest quality standards as British / Swedish / DCDMA / CDDA / Metric standards, and used around the world in a great variety of applications. We are the member of the National Drilling Association (NDA). We are committed in carrying out advanced technological research, and providing customers with products of outstanding quality and satisfied service.

Roschen drill rods are all manufactured by hgh precision CNC machines. They're made of high quality alloy steel. All our drill rods are heat treated. Our rods will also be suited to drill holes. They are very popular in global market.

Roschen series drilling rod is interchangeable with Q series coring drilling rod that is common in the international geological exploration industry. Taper threaded connection is adopted to facilitate connection and prevent stuck, and thread surface is hardened to greatly prolong service life of the thread.

Wireline drill rod has couplings that are nearly flush on the inside designed so that the inner tube of a wire line core barrel and overshot assembly can be run inside the rod. The rods are made of fine high-tensile steel and thin as possible so that core can be as large as possible.

Roschen coring rods are case hardened on the pin thread to maximum hardness – 60 HRC, creating a significant hardness difference between pin and box. This difference minimizes wear compared to the rapid galling that other threads experience.
