The Kelly is the pivotal drive component of the entire drill stem, expertly crafted to offer two distinct forms: square and hexagonal kelly. Each of these forms is meticulously manufactured in adherence to the stringent specifications of API Spec7-1 and SY/T6509-2000, ensuring impeccable standards and reliability.

Every aspect of the Kelly, from its ends to the drive cross-section and joint, is scrupulously processed and rigorously tested to meet the API standards, guaranteeing unmatched performance and durability.
