DTH Hammer at SHAREATE is suitable for a variety of drilling applications, including open pit mining, quarry blasting holes, wells, geothermal wells, and building pile holes, anchor holes and earthworks.

FOR BROCHUREGET A QUOTE

  • Product Overview

    DTH (Down The Hole) Hammer is a rock drilling tool which generate impacts at the bottom of the hole during the drilling process.The air passes through the drill pipe and enters the Hammer, pushing the piston to impact the DTH bit directly to drill. The air is then discharged from the DTH bit to bail the rock cuttings from the bottom of the hole.

    DTH Hammer can be categorized into two types.
    ● One is composed of parts such as a drive chuck,top sub, piston, inner cylinder, air distributor, guide sleeve, and check valve, with the top sub, air distributor, inner cylinder, and outer casing forming the air intake passage.
    ● The other type is composed of parts such as drive chuck, top sub, piston, distributor tube (feed tube), guide sleeve, check valve seat, check valve, with the top sub, distributor tube (feed tube), and piston case forming the air intake passage.
