It is mainly used for deep exploration drilling and ore grade control.It has the following characteristics:1.based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.3.The collection tube adopts an integrative design and can be replaced without disassembling the hammer. With carburizing treatment, it has good abrasive resistance.4.Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.REVERSE CIRCULATION DRILL BITThis reverse circulation drill bits are widely used in the following applicaitonfield:Geologic exploration samples, Oil wells and ore mining, etc. And it's specifically designed to work with RC Hammers.Specifications:1)face design: flat, convex, concave2)inserts design: spherical, ballistic, parabolic3)typical bit model: RE545, RE5474)bit diameter: 90mm to 213mmFeatures:1) reliable quality2) long service life3) smooth flushing effect4) designed to work with RC hammersDrill BitBit Dia.(mm)NO.AirHolesGaugeButtonsFrontButtonsWeight(Kg)PartNo.HRC11528×φ148×φ1314.0HRC45-11514028×φ168×φ1416.5HRC55-14016528×φ188×φ1619.5HRC65-165Mic13328×φ168×φ1417.5Mic-13314028×φ168×φ1418.0Mic-14014628×φ188×φ1420.0Mic-146PR513328×φ168×φ1412.5PR5-13314028×φ168×φ1413.0PR5-14014628×φ188×φ1413.5PR5-146PR411528×φ168×φ1314.4PR4-11512728×φ168×φ1415.0PR4-12713328×φ168×φ1415.5PR4-133Pictures:
