Asahi Wireline Drill Rods when used in conjunction with Asahi Wireline Core Barrels allow the core to be retrieved through the rods without removing the core barrel from the hole.
Our rods are manufactured from imported SAE grade 1541 Japanese steel for superior mechanical strength and straightness and are meticulously field tested in a variety of drilling conditions. They are heat tested and stress relieved through at both ends for 10”.
All N, H and HWT Wireline Rods as shown are compatible with “Q series” Rods.

The Asahi CHD76 Drill Rod is manufactured using high quality “tool joint” pin and box threads. It is friction welded to a “mid” body cold drawn tube stock. The threads give these rods unprecedented strength in both tensile and torque, coupled with the security of friction welded joints these rods surpass any other rod on the market for directional drilling.
These rods can be supplied in 1.5m or 3m pipe lengths and are pre-machined to suit internal survey equipment as standard supply.
