Product description:
Drill pipe slips type SD can accommodate drill pipes from 2.3/8 to 7 inch (60.3 to 177.8 mm). The are classified as type Short(SDS), Medium(SDML). Extra Long (SDXL) according to gripping length. SDS slips are designed for shallow hole drilling, SDML slips are the perfect choice for all medium depth drilling and SDXL slips are designed for deep drilling. They are designed and manufactured according to API Spec 7K Specification for drilling and well servicing equipment.
