Product DescriptionProduct DescriptionDTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock.Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.DTH Bits are essential drilling components designed for efficient down-the-hole hammer drilling operations in mining, quarrying, construction, and water well drilling. These robust bits feature a unique design with carbide buttons or inserts strategically positioned on the bit face, enabling them to withstand high impact forces and abrasive conditions.SpecificationHammer inchBits diameterShankMetricInch1"64mm-70mm2 1/2"-2 3/4"BR12"70mm-95mm2 3/4"-3 3/4"MACH20/BR23"90mm-102mm3 1/2"-4"COP32/COP34/MACH303M30/DHD3.5/BR34"105mm-152mm4 1/8"-6"COP44/DHD340/MACH44SD4/M40/QL405"133mm-165mm5 1/4"-6 1/2"COP54/DHD350R/MACH50SD5/M50/QL50/BR56"152mm-254mm4 1/8"-10"COP64/DHD360/SD6M60/QL60/Bulroc BR68"203mm-330mm8"-13"COP84/DHD380/SD8QL80/M8010"254mm-380mm10"-15"SD10NUMA10012"305mm-508mm12"-20"DHD1120/SD12NUMA120/NUMA125HammersBit ShankConnection ThreadSuitable bitWorking pressureAir consumption1-3" Middle-low pressureDTH hammersBR1BR2BR3RD40 boxRD50 boxAPI 2 3/8" RegΦ64-Φ76mmΦ70-Φ90mmΦ90-Φ110mm0.7-1.75Mpa0.7 Mpa4.5 m3/min1.0 Mpa4 m3/min1.4 Mpa5 m3/min3" hammersDHD3.5COP32/COP34M30API 2 3/8"RegΦ90-Φ110mm1.0-1.5Mpa1.0 Mpa4.5 m3/min1.5 Mpa9 m3/min4" hammersDHD340COP44QL40SD4M40API 2 3/8"RegΦ105-Φ130mm1.0-2.5Mpa1.0 Mpa6 m3/min1.8 Mpa10 m3/min2.4 Mpa15 m3/min5" hammersDHD350COP54QL50SD5M50API 2 3/8"RegAPI 3 1/2"RegΦ130-Φ156mm1.0-2.5Mpa1.0 Mpa9 m3/min1.8 Mpa15 m3/min2.4 Mpa23 m3/min6" hammersDHD360COP64QL60SD6M60API 3 1/2"RegΦ152-Φ203mm1.0-2.5Mpa1.0 Mpa10 m3/min1.8 Mpa20 m3/min2.4 Mpa28.5 m3/min8" hammersDHD380COP84QL80SD8M80API 4 1/2"RegΦ200-Φ279mm1.0-2.5Mpa1.0Mpa15m3/min1.8Mpa26m3/min2.4Mpa34m3/min10" hammersSD10NUMA100API 6 5/8"RegΦ254-Φ330mm1.0-2.5Mpa1.0Mpa22m3/min1.8Mpa40m3/min2.4Mpa55m3/min12" hammersDHD1120SD12NUMA120NUMA125API 6 5/8"RegΦ305-Φ381mm1.0-2.5Mpa1.0Mpa30m3/min1.8Mpa56m3/min2.4Mpa78m3/minPictures for ReferenceRecommend ProductsFAQ1.Why choose us ?Jimai Machinery is a very professional drilling rig supplier in China.
