Eccentric Drilling Tools With Casing Tube used for Subway tunnel Drilling, Water Well Grouting Hole
Eccentric Drilling System Tools With Casing Tube used for Subway tunnel Drilling, Water Well Grouting Hole
Product introduction:
Introduction to Eccentric Drills Eccentric drills are mainly used for: hardness, loose, broken or gravel rock formation drilling.
It is necessary to follow up the drilling of the casing at the same time, which has the advantages of good wall protection performance and high drilling efficiency.
Applications:
1. Blast holes
2. Water supply wells
3. Bridge and building foundations
4. Standard slant or horizontal drilling
5. Mining air holes
6. Environmental monitoring wells
7. Grouting operations
8. Seismic shot holes
9. Soil sample and geotechnical applications
10. Ground anomaly and tiebacks
11. Storage caverns and dam
Features:
1. High drilling efficiency
2. Save more More wind pressure
3. Eliminate the collapse of the hole
4. Drilled Hole is not bent and deformed
We are more professional:
1. With the industry-leading imported heat treatment technology, the hardness and toughness of the steel body are increased by 35%.
2. The alloy teeth adopt a professional over-pressure sintering process to greatly improve the strength of the alloy teeth.
3. The high-quality imported steel is used as the steel body of the product, the service life is increased by 30%, and the steel body is not broken.
4. Perfect after-sales guarantee system, quality problems occur, 100% return.
