R25 Threaded Drill Rod Hex 22/25mm Shank End rod For Drifting And Tunneling

Drill rod using R25 thread system. Suited for short hole drilling operations. For drills capable of receiving Hex 22x108mm and Hex 25x159mm shank. Used in drifting and tunneling.

Widely used in drifting, tunneling, benching, and long hole drilling

Material: Tungsten carbide and high strength alloy steel

Processing: CNC milling and proprietary heat treatment process

1.Our thread drill rods are made of high-intensity alloy steel imported from Sweden and shanghai baogang.

2.All the trails and threads are formed by high precision CNC machines.

3.For MF rod,we use mature friction welding technology to increase the using life of thread.

4.Holistic carburization increases the carbon content in the outer layer of drill rod, and hardened outer steel body.

5.The solid thread can fit perfectly with the inner wall of the drill bits,and complete various roadway tunneling, underground mining and open pit drilling task in complex rock and terrain rough drilling with high precision and high efficiency .

Our factory can offer many kinds of drill bits, including chisel type bits, cross type bits, tapered drill rods and integral drill rods, mainly used for mining, coal cutting, tunneling, rock cutting in quarrying.
