Round Extension Drill Rods

Threaded drill rods are also known as hydraulic drill rods and heavy-duty drill rods, which connect with shank adaptors, hydraulic drifters and drill bits to transfer impact power and rotation torque of hydraulic drifters onto drill bits for breaking rocks.

SHANDIKE Round Extension Drill Rods

Made from the same steels as Sandvik, produced by CNC machining and advanced heat treatment.

The threaded drill rods, working with hydraulic drill rigs and hydraulic jumbos, have main threads of R22，R25，R28，R32，TR35，T38，T45，T51，ST58，ST68 and T60.Features

• Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;

• 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.

• Cost-effective, good performance with reasonable price.

• Complete types of drill rod for various drilling scenarios.

Applications

The threaded drill rods are divided into MF rods and extension rods, which are widely used in open-pit mining, underground mining, tunneling, anchoring, furnace tapping, tunnel construction, hydropower engineering, quarrying and construction.

SHANDIKE is the first Chinese factory to manufacture drill rods and ranks the forefront in the industry in China regarding quality, sales volume, export volume, specification varieties and matching capacity.
