All hydraulic drilling machine
Application scope
All hydraulic drilling machine is suitable for drilling holes for mine
explorating. Also they can be used in railroad engineering,
tunneling and water conservancy project. It consists of power unit,
machine body, control panel, rotation unit, rod holder and slush pump.
Characteristic:
1. Oil pump driving the motor to rotate, hydraulic cylinder working without turret.
2. Hydraulic system allows for smooth rotation, fad, pulling, clamping and clutching of the machine.
3. Drilling fast at any angle.
4. V shaped guide way permits good centering of spindle.
5. Easy to operate, handle and disassemble.

9 7/8 K832 Mining Rock Bit Operation Instructions
Brief Introduction:
The strength and wear resistance of inserts are improved by using carbide inserts with high strength and high wear
resistance.Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the
load capacity and service life of the bearing.The service life of the bearing is further extended by adopting harder and
more wear resistant material for thrust bearing.Preventing reflux structure has dual function, it can avoid air counterflow
and dust entering into bearing when the air-compressor stop working accidentally; and separate air and water in order
to avoid water entering into bearing when it works normally to prolong the life of bearing.
Usage: The bit is used for air drilling, e.g., for drilling operations in open coal mine, iron mine and non-ferrous mine.
Applicable ranges: The bit is applicable for drilling hard and very hard formations with high compressive strength and high abrasiveness, such as magnetite quartzite, quartzite, granite, hard sandstone, dolomite, chert and ironstone, etc.
Basic Specifications of the Bit:
Weight on bit (WOB): 35000 – 70000 lbs
Rotary speed: 90 – 65 RPM
IADC code: 8—3—2
Rock Bit Diameter: 9 7/8 inches (≈250mm)
Type of the bearing: roller—ball—roller—thrust button
Cutting structure:
Top row and inner rows: ovoid compacts
Heel row: ovoid compacts
Operating Recommendations:
Shank: 6 5/8〞REG （API）
Weight: 59 kg
