Well Drilling Machine Parts MnNiMo Steel ＞100Mp Compressive Strength With Bullet Bits

Hard Rock Drilling Bucket Core Barrel Different Pitches Different Tool Height

We recommend Core barrel with bullet bits for strong rock up to 100Mpa or rock with deep cracks.We use core barrel with roller bits While for very strong rock formations with compressive strength greater than 100Mpa.

Adopting high-carbon steels and special drilling bits angle to keep the drilling strength and efficiency for rock Drilling Core Barrels with roller or bullet Bits ,they are both used to cut a ring in rock or concrete, mostly to initiate the borehole.

These tools are complete with options of tools boxes to match up with most drilling rigs in the market, including Bauer, Soilmec, IMT, Casagrande, Mait and so on. 

In addition, tools can be custom-built with different steel plate thickness, different pitches, different tool height, etc upon request.

1. All related accessories in the barrel are subjected to "heat treatment" process, which increase the strength and wear resistance of the product.

2. All welding processes are all 3 times to ensure the quality of the welding

3. Releasing rock confining pressure by barrel ring cutting.

4. Adopt high quality large diameter alloy round drilling bucket pick block increases the strength and wear resistance .

Applicable for Applicable for strong rock up to 100Mpa or rock with deep cracks.

Applicable for very strong rock formations with compressive strength greater than 100Mpa.
