Drilling Rig Φ70.15mm Precision Ground Drill Rod
Precision Ground Drill Rod Description
Drill Rod widely used in geological exploration, coal mining,
water conservancy & hydropower, highway, railway, bridge, building
construction etc.
The type have exploring water well rods, exploring water spiral
drill rods, outburst-prevention drill rods, DTH drill rods,
triangle drill rods, anchor-shank drill rods, extension rods, EU
drill rods, RC drill rods, KLEMM drill rods, Ingersoll Rand drill
rods etc.
Our drill rods produced by CNC machine, and choose high grade steel
material thru heat treatment of the steel tube & thread joint to
improve the steel material streagth and insurance the thread wear
life.
Precision Ground Drill Rod Specifications:
1. High quality alloy tube
2. Thru-wall heat treated tube body
3. Consistent concentricity, straightness
4. Tapered threads
Precision Ground Drill Rod Advantages:
1. Strong and ductile geological steel pipe;
2. Solid quality and considerate service;
3. Cost-effective;
Precision Ground Drill Rod Raw materials:
ROSCHEN only choose the best steel tubes in the market to
manufacture our rods and pipes. Spot check will be conducted after
the steel tubes delivered to company. We will make sure the
compositions and specifications match the inspection report form
the suppliers.
