Application

Applied in underground harsh environment to punch advance holes, coal caving holes, fire prevention holes, water and gas holes exploration holes and pressure measuring holes.

Features

● Safe

No auxiliary equipment required, and low maintenance, and minimize operator's fatigue.

● High speed of drilling

High-torque for startup, small moment of inertia, short time for acceleration and braking.

● Easy to install ,and simple operation

● High explosion-proof emulsion motor, and easy to get power source.

● Low noise to improve working environment of underground.

● Portable

Medium-low speed, high torque and high output. Using technology of anti-corrosion treatment for over-current components. Good wear resistance, simple structure, small size, light weight and easy to carry.
