Brief Introduction of USA Order:

1, Our USA customer is a project contrator in Birmingham, he contacted us by google.com.

2, His name is Steven, the PE in the Project Tunneling Drilling, all he is doing everyday is in charge of all the rock drilling tools purchasing and prjects supervising jobs all around USA. 

3, Mr Steven contacted us in year of 2018 and he only bought 20 pieces of some button bits R25 R32 and T38 Thread and Reaming Button Bits from us. we delivered different quality of carbides with different prices quotation, he chose the best of ours after testing the samples bits we delivered. Limestone and Bluestone sometimes will give you a headache in tunneling drilling. One of our T38-108 Mushroom Reaming Bits drilled about 400meters in the limestone with silicon, he is shocked by the result and now he told me a good news and a bad news too: Our bits are too good to keep purchasing more from us so he has confidence with our bits for drilling longer than the cheaper ones he bought before from China. 


Below is the Bits he used before and sample of bit was placed in his office, i took a picture when i visited him in his office. 

(Button Bit in phone: R32-51mm with 9 Carbide Tips)
