Heavy duty with a simple design
The rock drill has a heavy-duty yet simple design, with its percussion module consisting of only two moving parts. The piston and distributor sleeve remain separate from the drill body, minimizing contact with the drill body modules.
-
Multiple options available
Sandvik HL710S has two rotation motor variants to meet the rotation torque and RPM requirements of different hole diameters and rock formations. An optional power extractor can open rock tool joints manually.
-
High performance and low maintenance
