The Kelly serves as the pivotal drive component of the entire drill stem and is available in two exceptional forms: square kelly and hexagonal kelly. Each kelly, crafted with precision, adheres strictly to the high standards of API Spec7-1 and SY/T6509-2000 criteria, ensuring top-notch performance and reliability.
Our Square & Hexagonal Kellys are meticulously manufactured from AISI 4145H modified alloy bars, which undergo a comprehensive quenching and tempering process along their full length. This specialized heat treatment elevates their Brinell hardness to an impressive range of 285-341. Every aspect, from the kelly's end to its drive cross-section and joint, is engineered and verified to meet rigorous API criteria, guaranteeing superior durability and efficiency.
