BLADE
The 887 696 79 BLADE is a crucial internal component for the rotation motor in your rock drill. Working as a set, these vanes harness pneumatic or hydraulic pressure to generate the torque required for turning the drill string during operation.

Full Technical Description
887 696 79 BLADE Found inside the drifter's rotation motor, these blades are what convert pressure into mechanical force. As air or hydraulic oil is forced into the motor, it pushes against the blades, causing the rotor to spin at high speed. This rotational power is what ultimately drives the drill steel into the rock.
Continuous operation causes the tips and sides of the blades to wear down. This wear creates small gaps that allow air or oil to leak past, which directly reduces the motor's efficiency. When these blades wear, the drifter loses rotational torque, leading to slower penetration rates and difficulty drilling in fractured or hard rock.
If you notice weak or inconsistent rotation, it's a strong sign that the motor blades are worn. They are typically replaced as a full set during a scheduled drifter service or rebuild. Installing a complete new set ensures the motor is balanced and restored to its proper performance specifications.
Applications
- Underground drilling jumbos
- Mining and tunneling
- Hydraulic control systems
