Mills Machine custom manufactured stabilizers are used to keep the drill rod centered in the hole. They are available in a wide range of construction with all wear surfaces coated with carbide hard-facing.

All stabilizers are made with heavy walled steel pipe. Stabilizers larger than 8 1/2" OD are normally made with an inner as well as an outer pipe for rigidity and strength. There is full, direct flow circulation provided. We will discuss the specific design with you before accepting your order.

All stabilizers are made with 4142 heat-treated, steel tool joints. All ribs are fully welded on both sides and have hard facing. Optional replaceable cast carbide ribs are available to increase the gage life.

Mills offers five standard styles of stabilizers: Smooth, Flow Through, Straight Ribbed, Spiral Ribbed, and Straight-Spiral Ribbed.
