Product Description DTH(Down the Hole) hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling. Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs. Roschen offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.Product DescriptionDTH hammers without footvalve can be available.Different out diameters of out cylinder can be available.DTH bits 60mm-381mm for above hammers can be available.Products specifications: HammersBit ShankConnection ThreadSuitable bitWorking pressureAir consumption1-3" Middle-low pressure DTH hammers RD40 box 0.7-1.75Mpa0.7Mpa4.5m3/minBR1RD50 box64-76mm0.7-1.75MpaBR2API 2 3/8" Reg70-90mm0.7-1.75Mpa1.0Mpa4m3/minBR3 90-110mm 1.4Mpa5m3/min3" hammersDHD3.5API 2 3/8"Reg90-110mm1.0-1.5Mpa1.0Mpa4.5m3/minCOP32/COP34M301.5Mpa9m3/min4" hammersDHD340API 2 3/8"Reg105-130mm1.0-2.5Mpa1.0Mpa6m3/minCOP44QL40SD41.8Mpa10m3/minM402.4Mpa15m3/min5" hammersDHD350API 2 3/8"Reg/API 3 1/2"Reg130-156mm1.0-2.5Mpa1.0Mpa9m3/minCOP54QL50SD51.8Mpa15m3/minM502.4Mpa23m3/min6" hammersDHD360API 3 1/2"Reg152-203mm1.0-2.5Mpa1.0Mpa10m3/minCOP64QL60SD61.8Mpa20m3/minM602.4Mpa28.5m3/min8" hammersDHD380API 4 1/2"Reg200-279mm1.0-2.5Mpa1.0Mpa15m3/minCOP84QL801.8Mpa26m3/minSD82.4Mpa34m3/min10" hammersSD10API 6 5/8"Reg254-330mm1.0-2.5Mpa1.0Mpa22m3/minNUMA1001.8Mpa40m3/min 2.4Mpa55m3/min12" hammersDHD1120API 6 5/8"Reg305-381mm1.0-2.5Mpa1.0Mpa30m3/minSD12NUMA1201.8Mpa56m3/minNUMA1252.4Mpa78m3/minROSCHEN DTH hammer technical data:ROSCHEN DTH Hammers SpecificationsHammer SizeBit ShankROSCHEN CodeConnection ThreadSuitable bitWorking pressureAir consumption2"BR2ROS 11ROS 22 RD50 box￠70-￠90mm0.7-1.75Mpa0.7Mpa4.5m3/min1.0Mpa4m3/min1.4Mpa5m3/min3"DHD3.5ROS 32API 2 3/8" Reg￠90-￠110mm1.0-1.5Mpa1.0Mpa4.5m3/minCOP32/COP34M301.5Mpa9m3/min4"DHD340ROS 34API 2 3/8" Reg￠110-￠135mm1.0-2.5Mpa1.0Mpa6m3/minCOP44QL40SD41.8Mpa10m3/minM402.4Mpa15m3/min5"DHD350ROS 52ROS 54API 2 3/8"Reg/API 3 1/2" Reg￠135-￠155mm1.0-2.5Mpa1.0Mpa9m3/minCOP54QL50SD51.8Mpa15m3/minM502.4Mpa23m3/min6"DHD360ROS 62ROS 64API 3 1/2" Reg￠155-￠190mm1.0-2.5Mpa1.0Mpa10m3/minCOP64QL60SD61.8Mpa20m3/minM602.4Mpa28.5m3/min8"DHD380ROS 82ROS 84API 4 1/2" Reg￠195-￠254mm1.0-2.5Mpa1.0Mpa15m3/minCOP84QL801.8Mpa26m3/minSD82.4Mpa34m3/minM80/M8510"SD10ROS 100API 6 5/8" Reg￠254-￠311mm1.0-2.5Mpa1.0Mpa22m3/minNuma1001.8Mpa40m3/minROS 1002.4Mpa55m3/min12"DHD1120ROS 120API 6 5/8" Reg￠305-￠445mm1.0-2.5Mpa1.0Mpa30m3/minSD121.8Mpa56m3/minNuma1202.4Mpa78m3/minNotes:Metzke, Remet thread is available!Any special typ shank of DTH Hammer will be available by requests.Quality warranty:Our hammers are made of high quality steel and all spares are inspected strictly before shipping.
