Drilling Equipment API Hexagonal Drill Kelly

Hexagonal drill kelly are made from AISI 4145H alloy bars that are quenched and tempered full length. A hardness range of 285 to 341 BHM and a minimum impact value of 54 Joules as per ASTM A 370 are maintained one inch bellow the surface at room temperature. To improve resistance to galling, all connections are phosphate-coated with an API thread compond. Each bar used to manufacture kellys has been examined with magnetic partice inspections and ultrsonic inspections.
