The R500 handles directional drilling an a range of rock conditions
The new HammerHead Roughneck R500 pneumatic rock hammer system can drill 6.25-inch-diameter holes at penetration rates of up to 150 feet an hour.
The R500 is larger than the R400 that HammerHead introduced last year. Key features it offers include high-flow housing, 6.25-inch straight and offset bits, a pullback kit, control station/oiler and drill conversion kit. Its housing boasts a larger bore diameter, allowing the hammer to send more air to the internal piston for maximum efficiency, which results in faster, harder blows.
