Bulroc Hyper 125/300HF DTH Hammer

Hyper 125/300HF Valveless Hammer - 13" to 17 1/2" diameter holes

The Bulroc Hyper 125/300HF is designed specifically for drilling shallow holes in soft/medium strata due to the lighter piston and increased blow rate. The Bulroc Hyper 125/300 HF is especially suited to the N125 shank, but other conversions are available on request.

The Bulroc Hyper 125/300HF is fitted with a 6 5/8" API regular pin as standard, complete with a positive seating water check valve. The control tube choke is supplied solid as standard.
