Down The Hole Drilling Tools / Top Hammer Drilling Tools For Water Well Drilling
Description:
1- We really do the high-end quality, low-end price.
2- We have an independent quality testing center with complete testing equipment to achieve 100% inspection before shipment.
3- We can order all kinds of non-standard products according to customers' drawings and requirements. Sincerely welcome you to visit our factory for on-site inspection.
Applications:
The medium-deep hole blasting has been gradually implemented in the mine, so it is inseparable from the DTH drilling tool. Compared with hand wind drills, whether it is safety, reducing the labor intensity of workers, improving the working environment, or increasing rock drilling rate, production efficiency, and increasing enterprise efficiency, down-drilling tools have advantages that are unmatched by hand drills.
DTH drilling tools mainly include down-the-hole drilling rigs, down-the-hole drill pipes, down-hole impactors and down-the-hole drills. From the raw materials entering the factory to the finished product delivery process, we always adhere to high quality and strict requirements. Strict incoming inspection, high-precision process equipment, advanced heat treatment equipment, reasonable and smooth process flow, and complete and precise corporate standards are prerequisites for the production of high-quality down-the-hole drilling tools.
