SPIRAL DRILL ROD
High-efficiency spiral drill rods to meet the practical needs for water and gas exploration, and injection in underground coal mines. It features square coupling for rods, makes for easy assembly and disassembly. Tension-resistance of up to 1323.89 MPa by using special steel alloys and preparation techniques. Matching our drilling machines with spiral dry drilling technology, makes for high drilling speed and drilling efficiency. Compared with traditional drilling technology, it can avoid torsion and bend stress effectively and improves the drilling speed.

Available with boring diameter from 38mm up to 96mm with 13mm² up to 32mm² connections. Hexagonal connections of up to B41 is available.

COMBINED DRILL BIT
Drill bits made of high-grade alloy steel for ensuring drilling efficiency. Because of deep drilling, the strength and toughness of drill bits must be exceptional. All the alloy segments are imported from abroad and selected through nanometer techniques to ensure and improve the hardness and strength. Adopting a low-temperature vacuum pervasion welding method to ensure high efficiency and increased durability.

Sizes vary from 42mm – 108mm diameter with 13mm² to 24mm² connections. Hexagonal connection sizes of up to B41 are also available.

ANTI-COLLAPSE COMBINED DRILL BIT
Anti-collapse high efficiency combined drill bit is of superior strength and design. It adopts a multi-step drilling mode. Step 1: Two wing segments. Step 2: Three wing reaming segments. Step 3: Anti-collapse segments, making it efficient under collapse circumstances when drill reverse rotates.

GEOLOGICAL DRILL BIT SET
The body is precision designed, machined by CNC Lathe, top class diamond segment guarantees long life and fast drilling. The bits can be used together with various drill machines for underground coal mining.

GEOLOGICAL DRILL ROD
For maintaining the linear effect during drilling, it is manufactured of special steel and advanced friction welding methods with the following features: High strength, strong welding, extended service life, etc.
With material of top quality alloy, which has been heat treated, the connector features powerful wear-resistance, and unparalleled shear-resistance. All the machined equipment are manufactured using advanced digitally controlled lathes, producing products which offer extreme efficiency and quality.

DRILL ROD
Manufactured from high-quality hexagon steel, high strength, extra tough, wear resistant and easy to assemble. The length is from 0.6m to 2.5m, and can be customized.

ROD CONNECTOR
The Drill rod connector is the coupling between drill rods and the drill bit. Our products made from special steel and are heat treated, ensuring maximum intensity, a longer lifespan, and trouble free service.
