Four designs are available as below:
1) Integral spiral type
The Integral spiral stabilizers are made from AISI 4145 H Modified alloy steel or Non-magnetic alloy steel, the pressed button type or applied tungsten carbide hard faced on the blade.
2) Intgral straight rib stabilizer
3) Interchangeable sleeve stabilizer
Interchangeable sleeve stabilizers are made of 4145 H Alloy steel, heat-treated to 285-341 Brinell Hardness and 54 Joules minimum impact value. All physical properties would be guaranteed 1" under the surface. The stabilizer is constructed of two pieces, which are jointed, by the center mandrel and one sleeve.
4) Sleeve stabilizer
