Integral Spiral Blade Stabilizer

Integral Spiral Blade Stabilizerntegral Spiral Stabilizer is a one-piece tool made by AISI 4145H alloy steel and fully heat-treated to 285-341 Brinel Hardness number, and 54 Joules of minimum impact value. Three spiral blades have been designed to minimize the downhole torque, to reduce damage of the hole wall, and ensure the maximum fluid circulation. When drilling vertical holes, they shall be applied to reduce drift of drill bits and keep the drill bit straight downward. When drilling directional holes, they can increase, decrease or stabilize the tilt of the hole, to ensure the orientation of the hole, to ensure the quality of the well, and increase the drilling speed.

Replaceable Sleeve Stabilizer

Replaceable Sleeve StabilizerInterchangeable Sleeve Stabilizers are made by AISI 4145H alloy steel and heat-treated to 285-341 Brinel Hardness number, and 54 Joules of impact value. For each body, a series of sleeves can be fitted with it; the body is constructed in two pieces, and jointed together by the sleeve.
