Describtion：
Our sub saver will keep your drill rod threads safe and sound. Boost your drive chuck’s life by adding a replaceable sub-saver to bear the brunt of the wear so your drill rod threads don’t have to. Changing out worn sub-savers and drive chucks is an inexpensive and easy way to get the maximum life out of your drill rod. If they are allowed to wear too much, a drill rod’s threads will start to deform to the shape of the worn sub-saver threads.

Performance Features:
·Drive chucks are built to the exact specifications of the original equipment manufacturer.
·Made of high-alloy steel for high strength and durability.
·CNC-machined for a perfect match with your drill rod."

165 / 172 High torque drill rock motor : High speed of revolution

Cavity Probe High Flow sub : Signal resistance is small improve accuracy of orientation

Mud Flow area is Large to lower cycle pressure and improve ability of sand return ;

Damping device is equipped in the cabin , which could protect cavity From not being damaged by vibration efficiently It protects cavity probe against shocks and extends service Life

Product Description
HDD swivel is an essential part for all horizontal directional drilling works .

HDD pull-back swivel must be able to bear both the pull strength imposed by pull-back actions and swivel strength and side-load resulted From rock or other conditions , Bearings of the swivel joints here at our company are suitable for absorbing thrust and radial Load . Our HDD swivel joints adopt specially designed sealing elements , whichcan prevent an early Failure of bearings resulted from entry of dirt into the bearings , The pull-back swivel joints here at our company are available to undertake mud ,  dirt and any other underground objects and they are easy For maintenance.

Features

3 . Longer service Life and greatly reduce construction risks
4 . It is easy For dismantle and maintenance

Pull tabs is made by alloy steel and heat treatment , clevis consists of bow cross pin and nut
Features
1 . 100% screw thread inspection
2 . Made of heat-treated alloy steel
3 . The clevis pull tabs is diversified in sizes , perfect For all drilling equipment obstruction

Our cutting tool can be matched with different tool bits For varied geological conditions to improve the cutting efficiency of the reamer.

We are able to provide optimum drilling products for you according to your specific needs and we are devoted to developing more products in this field.
