King Oil Tools offers the 75WP swivel for drilling deep water wells, deep slim-hole drilling, heavier work-over rigs and drilling medium-depth oil wells. The 75WP is a sturdy swivel with a very high ratio of capacity to weight. This swivel is available with the conventional bail, or it will be furnished with an elevator shank in lieu of a bail. Alloy steel is used throughout in the manufacture of this swivel, excepting some minor parts constructed of bronze where that metal is more suitable. The bearings are angular-contact-type ball bearings, and the thrust bearing is a unit of four bearings mounted tandem.
