DCR20 Down The Hole Drill – Reliable and Proven Performance

The DCR20 is a proven and reliable resource for drilling operations around the world.

These drills have been tested in soft, medium and hard rock conditions with multiple end-users and applications providing deep holes from 3.5″ to 6.5″ at fast drilling rates with low maintenance.

Servicing the DCR20 is easy.   There is access to all key components – such as the engine, fluid levels and compressor – through large panel doors located at ground level for maintenance when needed.

The redesigned cabs provide operators maximum comfort with single-lever drilling controls, large gauges and superior views of drilling operation.
