About our Product Technology and Advantages
“WORLDRILL”,manufacturing drilling tools, is a leading brand in China, and the DTH Hammers without foot-valve are the most popular products in particular. Compared with the DTH Hammers of the same specification with foot-valve, the advantages of DTH Hammers without foot-valve are as follows: 1. Higher impact frequency and faster drilling speed, with the speed being 15%-20% higher than the ones with foot-valve; 2. Lower air consumption and lower oil consumption, with 10% of the oil consumption saved; 3. Avoid the trouble of foot-valve fracture and expand when heated, or the contraction when cooled; 4. Fewer internal parts, simple in structure, long in service life, and easy to assemble and disassemble. The new type hammer has been well received by users since its launch. Hammering tests have been carried out on the hardest iron ore mine in China. Compared with the products from SANDVIK and ATLAS COPCO, the new type fast hammer produced by our company is about 10% faster in terms of speed. Besides, since the thickness of the external cylinder of the hammer from our company is increased, its service life is longer than others. As to bits, the quality of products provided by our company is comparable to those from the above mentioned two companies; in the meantime, the cost performance of drilling tools branded “WORLDRILL” is much higher than those branded SANDVIK and ATLAS COPCO.
