8 1/2" 215.9mm 4 wing bit
8 1/2" 215.9mm 4 wing bit
1.Characteristics
1) Super long life-as 10 times as cemented carbide drill bits under the same condition. 2) High efficiency-Times of lifting the drilling machine could be reduced sharply, and the average
time efficiency could be increased more than 2 times. 3) Wide range of application-it could have a penetration of rock formation with f ≤12, especially
for the rock formation with f=5-10.
