DTH Hammer

KSC SPEED Valved D.T.H. Hammer are robust tools of simple design to provide for maximum performance with the minimum of maintenance.

KSC-Speed Valved Hammer are designed to operate efficiently at air pressure, between 100 psi (7 BAR) and 250 psi (17.5 BAR) using a wide range of Button Bit diameters, from Ø60mm (BR1) through to Ø127mm (BR4)

KSC-Speed Valved Hammers are supplied with a check Valve arrangement which maintains pressure in the hammer when the air has been shut off, and so helps prevent contaminated water entering the hammer.

KSC-Speed Valved Hammers are fitted with an Air Metering Plug. This is supplied as a solid plug, but can be drilled out to a selection of hole sizes in order to increase the volume of flushing air, if excess compressed for air is available. This is to suit particular drilling conditions.
