Rotary speed of hole opener

Pull force and rotary speed is very important specification of hole opener. But it’s very regret that many HDD drilling rigs don’t have instrument to show rotary speed of hole opener. As drilling tools manufacturer with over decade’s experiences, we have chance to compare roller bits working in different fields. Read more…
