Crushed tungsten carbide held in a nickel bronze matrix.The 3 mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.
Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage – ideal for high deviation drilling in abrasive formations.
Tungsten carbide inserts set in a powder spray deposit ideal for abrasive formations. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non- magnetic stabilizers.
Tungsten carbide inserts (button type). The inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.
This oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provides excellent bonding properties and greater surface wear characteristics are achieved. Surface hardness levels over 40HRC. Idear for GEO-THERMAL applications over 350°
This process is a highly automated way of applying hard face and utilizes a combined arc/plasma stream on the work piece surface. This results is low base metal dilution and a dense,uniform coating, the filling medium can be variety of hardfacing consumables.

Integral Spiral Blade Stabilizer
ntegral 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
Interchangeable 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.
