Bulroc Hyper 63 DTH Hammer

Hyper 63 Valveless Hammer - 6" to 8 1/2" diameter holes

The Hyper 63 is a valveless DTH Hammer designed for drilling 6" to 8 1/2" diameter holes over a wide range of operating air pressures. It is especially suitable for waterwell drilling applications where greater depth requirements demand less air usage with minimal performance loss. The Hyper 63 is supplied with a 3 1/2" 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 63 Hammer is designed to accept Button Bits with a shank and footvalve identical to the Ingersoll Rand DHD 360. However, the Hyper 63 can also be supplied to accept the Mission SD6 and XL6 type of Button Bits.
