Product Advantages

1. Fully Hydraulic System for Surface Drilling

The SDC150H combines hydraulic machine functions with a pneumatic down-the-hole hammer. The hydraulic system operates the drilling and machine mechanisms, while compressed air powers the hammer positioned behind the drill bit. This configuration is designed for surface rock drilling applications where drilling consistency, machine control, and reliable operation are important.

Actual drilling performance depends on rock strength, abrasiveness, hole diameter, hammer selection, compressor operating conditions, bit design, and operator practices. Buyers should evaluate the complete drilling system rather than relying on engine power alone.
