Bulroc Hyper 63HD DTH Waterwell Hammer

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

The Hyper 63HD is a valveless DTH Hammer designed for drilling 6 1/2" to 8 1/2" diameter holes. This heavy duty hammer is specifically designed for waterwell drilling applications where greater depth requirements demand less air usage with minimal performance loss. The Hyper 63HD 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 63HD Hammer is designed to accept Button Bits with a shank and footvalve identical to the Ingersoll Rand DHD 360. However, the Hyper 63HD can also be supplied to accept the Mission SD6 and XL6 type of Button Bits.
