Description

Various Products . >>PDC drill bits: New products with super long life, high efficiency and wide application. 1) Super long life-as *0 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 ≤*2, especially for the rock formation with f=***0. PDC drill bits (non-core bits) Application for penetration of gas hole, water-discharging hole, and grout hole under coal mine. Size: dia **-dia **0mm Concave model Pillar model Blade model Expansion model PDC Drill bits (core bits) Application for core drill of coal system stratum with hardness coefficient f<*0 in geological exploratory. Size: dia **- dia **3mm
