    Description

    Tool, where applicable, updated in accordance with governing API standards

    SDS, SDML, SDXL and SDHL Rotary Slips are for use in API standard insert bowls. Featuring better contact and distribution of load on drill pipe thru a superior wraparound configuration and unique insert design, these slips prevent bottlenecking and gouging damage. The buttress design of the body segments provides great strength while minimizing weight for ease of handling.
    National Oilwell Varco's Rotary Hand Slips have gone through two product enhancements. For increased safety on the rig floor, "Flex-Handles" are now used on all rotary hand slips. Load rings* have been added to the SDHL for handling heavy strings of drill pipe.
