It uses water horsepower to drive cutters work, it has structure reasonable and convenient maintenance, faster cutting speed. When cutting multi-layer non- concentric casings, It could bear drastic shaking. Strong cutter arms can extend to 5 times as much as body diameter, so that get max stability performance under all kind of disadvantage cutting condition( including hard point, concentric, cutting discontinuity), such as 13-3/8" marine cutter body diameter is just 11-3/4", but the max cutting range of pipes reach 60".Specification ModelODmin(inch)Conn.Casing ODMin (inch)Max (inch)GD111111(4 3/8)2 7/8REG5 1/26 5/8GD146146(5 3/4)3 1/2REG716GD203203(8)NC509 5/830GD238238(9 3/8)6 5/8REG10 3/436GD298298(11 3/4)6 5/8REG13 3/860How to Order:Sizes & connections;Please specify special requirements.Mechanical Internal CutterMechanical internal cutter is a tool which is used for cutting downhole fixed pipe from inner of casing, it can working in any place except joint and collar.SpecificationModelCasing/Tubing OD (inch)Cutter OD (mm)Cutting Thickness (mm)Conn.ND-732 7/8575.51.9TBGND-893 1/2676.51.9TBGND-1024855.7,6.72 3/8TBGND-1144 1/2897.4~10.92 3/8TBGND-12751025.59 - 112 7/8REGND-1405 1/21207,7.7,9.2NC31ND-1686 5/81497.3 - 8.9NC38ND17871465.87~13.724 1/2REGND2449 5/82127.92~13.846 5/8REGND34013 3/82958.38~12.196 5/8REGND47318 5/844011.056 5/8REGND5082047011.13~16.136 5/8REGHow to order:Sizes & connections;Washover PipeWashover pipe is a necessary tool in washover operation which can relieve all kinds of sticking in the well.

Roller Kelly BushingRoller kelly bushing is one of the necessary tools for oil drilling operation, which is fixed at the big bushing to pass the torque to the down hole drilling tools.According to the driving mode, it could be divided into square drive type and pin drive type. According to the kelly, there are square kelly bushing and hexagonal kelly bushing. It mainly consists of roof cover, bottom cover, axls pin, roller, fastening bolt and stals, etc.There are four pieces of roller in the bushing which have needle bearing inside the rollers and fastened between roof and bottom cover by and pin and seals at both ends of rollers to prevent the drilling fluid from percolating. There is a stop pin fixed in the seal body to prevent rotating.The axles of roller is fixed by four pieces of bolt M38 which tightening torque is 2KN-m. There are four hexnuts fixed the top of four large bolts with the covers tightly to avoid loosing.Specification:Model(inch)Bottom SeatOpposite Side mm(inch)Large End of the Taper mm(inch)TaperGBX3-1/2332(13 1/16) (520 rotary table) 342(13 15/32) (17.5 rotary table)330(13) (520 rotary table) 332(13 1/16) (17.5rotary table)1:3GBX4-1/4GBX5-1/4model(inch)rotary size(inch)drive hole ODmm (inch)drive hole center distancemm(inch)GBX 5-1/4"37 1/2"86.233 (3 25/64)654 (25 3/4)GBX 3-1/2"37 1/2"86.233 (3 25/64)654 (25 3/4)BJ WiperThe wiper is one of the obbligato tools in downhole operation, which is used for cleaning mud on drill pipe outer surface to protect drill pipe outer surface cleaning, in order to make all drilling tools work normally.SpecificationWiper OD (inch)Drill Pipe OD (inch)16 3/42 3/8,2 7/8,3 1/2,4,41/2,5,5 1/2,5 7/8,65/8How to order:Sizes & connections;Please specify special requirements.U WiperType u wiper is used for cleaning mud on the surface of drill string in drilling operation.
