Lake reverse circulation junk basket (rcjb) is designed to remove all types of small junk objects from the hole. The tools main feature eliminates pulling a wet string. Even when the tool is fitted with a magnet insert, reverse circulation is maintained.
Operation:
Lake reverse circulation junk basket is made up to the bottom of the fishing string and lowered to a point within several feet from the bottom of the hole. Begin circulation to wash the hole. Stop circulation and drop the steel ball. (when the steel ball is dropped into the valve seat, circulation fluid travels outward and downward through the inner passage of the barrel and out through the vents in the lower end. The fluid is then deflected to the center of the tool and up through the return holes in the upper end of the barrel. This reverse fluid circulation carries the junk into the barrel above the junk catcher.) begin circulation again, slowly rotating while lowering the tool until a 10â?? core has been cut. Stop rotation and circulation and pull the tool from the hole

The down-the-hole hammer is a new type valveless hammer driven by compress air.It is the ideal rock drillling tool with advages of large impact energy,high penetration rate,long service life,good efficiency of drilling cuttings removal,easy operation,reliable working performance and so on. TH----for wet drilling Wadely applied to all kinds of rock boring hole drilling and excellent in projects for casing system and water well drilling. Can be matched to various types of hammers popular in the world and drill the holes from 76mm to 1200mm in diameter. TS----for deep hole and super deep hole drilling Can be meet to the needs of drilling holes from 203mm to 660mm in diameters. TG----for drying drilling Have stable performance, fast speed, long service life in sleeves, and 10% less air consumption than other ordinary hammers, and can also work well without the foot valves. Drill holes from 90mm to 254mm. All our Hammers can be easily adapted to accept different types of bit shanks as COP, BR, DHD, SD, XL QL, MACH, Halco and Mission by simply changing a few basic components. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions. In wooden case or in carton

Junk Trapper and catch One Salvage cup usually pick up on the drill bit or milling tool, with its collection of cups will circulate in borehole couldn't recovered heavier small falling objects.It can also be used for casing scraper above, make the casing scraper operation is fast and clean. TwoSalvage cup salvage fragments falling object is mainly used in drilling process, such as cemented carbide teeth, bit bearing, etc.It is to keep the bottom clean, improve the service life of drill bit, drill bit to reduce and prevent accidental damage plays an important role. Structure Salvage cup is mainly composed of spindle, wiper block, outer tube, the joint and so on, as shown.Because the manufacturer is different, although its structure is similar, but not exactly the same, can be selected according to downhole conditions.
