JD-1400E-II

The new JD-1400E-II series began production in 2019.  Keeping with the tradition of the JD-1400E series, we utilize a simple design and industry-proven components for the new JD-1400E-II.  Its affordable price point offers an economical yet dependable alternative to overpaying for the technology you don’t need in today’s competitive market.

In recent years, rock drills that have entered the market have become increasingly too advanced, complicated to be maintained, and serviced by owner/operators regularly.  The Rock Commander defies this trend.  Along with the increased production and ease of operation, The Rock Commander JD-1400E-II is offered at a very competitive price when compared to other existing drill options in North America.

The JD-1400E-II Rock Commander can drill deep holes from 3.5 to 5 inches (89 to 127mm) in diameter with fast drilling rates with low maintenance cost.  The JD-1400E-II is powered by the Cummins QSL9 engine, with the new larger GHH Rand Compressor and the YH135 Drifter. The drill powers its way through the rock, increasing your bottom line.  The new larger cab design, with a tilt console, makes the operator more comfortable to help improve the overall productivity.

Through our customer inputs, we improved on JD-1400E to develop the JD-1400E-II series.  Our customer’s inputs are the driving factor for the Rock Commander series.
