Bulroc Hyper 41 DTH Hammer

Hyper 41 Valveless Hammer - 4 1/8" to 5" diameter holes

The Hyper 41 is a valveless DTH Hammer designed for drilling 4 1/8 to 5" diameter holes over a wide range of operating air pressures. The Hyper 41 is supplied with a 2 3/8" API regular pin backhead as standard, but other connections are available on request. A positive fitting water check valve guards against ingress of ground water when the air is shut off.

The Hyper 41 Hammer is designed to accept Button Bits with a shank and footvalve identical to the Ingersoll Rand DHD 340A. However, the Hyper 41 can also be supplied to accept other types of Button Bits, including Sandvik Mission SD4, XL4, and Halco Mach 44.
