Based on the installation place, this stabilizer may be divided into two types: the drilling string type and the near bit.

 The working hardfacing surface (also called wall contact) materials available separately are

 (1) carbide insert, 

(2) inserted diamond compound, 

(3) low temperature brazing tungsten carbide slug, 

(4) surface bead welding abrasive welding rod, etc. 

Built with inserted round carbide in spiral ribs, the product is characterized by high hardness, good toughness and powerful wear resistance, as well as long service life.
