Surface of reamer is designed to be smooth to reduce resistance;
High-strength steel plate is adopted for the curved head, with the wall thickness to be 12-18mm
The straight strip area of the reamer is welded to be wear resistant to extend the reamer's life;
Length of the wear resistant region is customizable;
The straight strip area will squeeze the wall to improve the wall's strength as the reamer rotates;
The reamer is formed from high-strength steel plate with a wall thickness of 12-18mm
The perfect combination of conical and the strip part helps to reduce resistance when the reamer works;
The conical body and the straight part are welded into a piece so the conical part will bear more load;
The high-strength wear resistant welded strip has largely extended the reamers' life
Cutters of the reamer are welded from high-strength alloy;
Each cutter is designed with a nozzle to cool them down and protect the cutters;
Users can apply nozzles with different diameter according to different construction conditions
The reamer and rod connector is connected with all-direction sleeve nut for easy assembly;
The coupling of all-direction sleeve nut and tubing joint is in line with API standards;
The external reinforcement and mandrel can bear the force;
