Test record of high wind pressure impactor

ince its advent, Qi Deli impactor has been widely praised by many users. In order to better serve customers and track the quality of products, our company carried out the use test of high wind pressure DTH bit and high wind pressure DTH impactor in Xindu Town of Putian City on September 2, 2016.

The granite of the test site was professionally analyzed to be 654 granite, with a very high hardness of about F14~16. The results of the experiment are recorded in the following table:

On the spot, we invited some distributors to verify with the users. After analysis and summary, the single-rod drilling time and service life of the Qideli impactor are similar to that of the Black Diamond. In terms of gas consumption, the Qideli impactor is smaller than the Black Diamond. They are very satisfied with the use of the effect, put forward a lot of more constructive suggestions, unanimously agreed that the Chideli impactor is a high-quality, cost-effective impactor.
