Product description

Pneumatic piercing tool (with reverse mode) complete with active head designed for horizontal operations


  • Hand installation of Ø25-75mm plastic pipes
  • Installation of Ø63-75mm plastic pipes directly(only HP95RM version)
  • Installation of fibre cables, power and gas lines

Additional informations

HP95R is designed for piercing and trenchless installation of PE & PCV pipes up to 75mm diamater. Installation method involves direct pulling of the pipe behind the mole with the use of steel rope and tension plate.

HP95R mole is equipped with active head which improves accuracy. Active head works in 2+1 system which means that energy that comes from first two impacts is used for breaking and pushing the soil away from the mole. Third hit pushes corpse forward. As a result HP95R mole is very effective tool.

It is recommended to use HP95R mole in hard soils such as dry clay, shales because the energy of the piston is transfered directly onto head which works more efficient.

HP95R is recommended for the approximate range of works:  

80% of plastic pipes installation up to Ø75mm, 20% of plastic pipes installation with smaller diameter.

Reverse mode is switched on by pulling the air supply hose out (there is no need to turn the hose). Easy and safe switching of operating mode allows efficient piercing and also allows to quickly reverse the mole in emergency situations. Very important factor is that switching reverse mode on doesn't require turning air supply hose which might be difficult. Sometimes it might not be possible due to lack of stiffness of the air supply hose when mole is far deep in the ground from the entry pit.

HP95PR is modified version of HP95R mole with the same range of operation. It is equipped with pneumatical reverse mode applied by changing position of the valve built into the steering-lubricating station

HP95RM and HP95PRM modified versions of HP95R/HP95R and are equipped with special end nut called pipe pulling tube that allows pipe installation in the first operation.

HP95R is also available as short version HP95KR. Same as basic model it is designed to install pipes and cables of the same diameters. Mole has shorter corpse, lower weight and low air consumption. It's very handy and comfortable to use. Customer pick that version for works with limited space available for excavations. 



It is not recommended to work with the mole in marshy ground. In such condition it is advised to ram steel pipes but HP95R/HP95KR mole due to active head presence isn't adapted for pipe ramming and use of expanders.

HP95R model and its modified versions is not designed for pipe ramming & mini piling. Suitable mole for these operations is HP95.
