Sandvik HL820T hydraulic rock drill is designed for drilling 64 - 127 mm diameter holes in Sandvik hydraulically controlled surface long hole drill rigs.

Sandvik HL820T is a heavy hydraulic percussive rock drill with independent rotation and separate flushing. High drilling capacity and reliability are enabled by functional modules. Sandvik HL820T is equipped with a hydraulic stabilizer to control contact between drill bit and rock. This ensures optimal drilling performance with high drill steel life time. Three rotation motor options are available for torque/speed adjustment.

Optional Power Extractor guarantees trouble-free drilling in extreme conditions. The design is covered by several patents.
