China made Drilling machinery Core barrels drilling tools with Roller Bits
Advantage
1. Larger Holes with Smaller Rigs. By drilling a hole in stages, larger holes can be drilled with smaller rigs. A smaller hole requires less power.
2. Replacing Cutters and Cutting Cost - On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit.
3. Flexability. Hole Openers can be fabricated in just about any size, and can be configured to drill through any formation.
4. Number of Cutters - The number of cutters placed on a hole opener is governed by the following facts: Maximum number which will fit around the perimeter; The greater the number of cutters, the smoother the tool will run; The greater the number of cutters, the greater the cost.The greater the number of cutters, the longer the cutters will last
Feature
1. Cutting ring with rock drilling bits and releases the internal stress of rock；
2. Drilling with the method of rolling and squeezing can increases the anti-wear ability of the barrel;
3. Small barrel facilitates the coring operation; large barrel performs stage breaking;
4. Applicable layers: backfill layer, medium weathered rock, bedrock;
Customizable Items
1. Cutting DIA. Custom : design various cutting diameter based on demand, like φ850,φ1150 etc.
2. Shell HIT. Custom : design as demand, prolong or shorten, increase of efficiency by drilling more.
3. Key Component Reinforce Custom : strengthen the key component to extend life cycle;
4. Kelly Box Custom: custom Kelly box size based on the Kelly bar, like 130*130, 150*150,200*200 etc;
5. Teeth No. Custom : encrypt the drilling teeth based on demand etc;
