Language
Cylinder bore：82mm
Piston stoke：60mm
Impact energy：≥70(0.63Mpa)J
Working pressure：0.4Mpa~0.63Mpa
It is suitable for rock drilling operations in large mines, medium mines and tunnels.
Features
Wide range of use
Suitable for drilling horizontal and inclined holes in rocks ranging from soft to hard
Efficient drilling with low energy consumption
The diameter of the blast hole is generally φ34-45 mm, and the effective and economical drilling depth is 5 meters.
Forging technology makes drill more durable
With forging technology，lower rotational speed at the same drilling depth，making drill more durable.
Accessories of strong universality
Accessories of strong universality,when replace the product,users will not lose profit.
