5 inch Mission Hammer

DTH hammer for 133–152 mm holes, compatible with the Mission 50 shank.

ÜRÜN AÇIKLAMASI

5 inch Mission Hammer works with bits using the Mission 50 shank in 133–152 mm holes. It is suitable for water wells, geothermal work and medium-diameter rock drilling.

Feed pressure, rotation speed and lubrication should be adjusted to the formation. Water and dirt in the air line shorten the service life of internal parts, so clean air and regular maintenance are important.
