Product feature of  Rock Drills

HL710S hydraulic rock drill has high drilling capacity, easy maintenance and low operating cost.
The structure of the rock drill is based on the main module and four short-side bolts connected together to ensure a minimum number of joint surfaces and large contact surfaces.
The design of the influence module is simple, consisting of only two moving parts, the piston surrounding the piston and the distributor sleeve, and the moving part is not in contact with the drill body module.

There are two variants of the rotating motor to meet the requirements of different hole diameters and the rotation torque and speed of the rock formation.
The optional power extractor is used to manually open the rock drilling tool joints. The design of HL710S has obtained a number of patents.
