Varco Style 2620 Button Die for DCS-S & DCS-R Slips | Pan P/N 20220
The Varco Style 2620 Button Die (Pan P/N: 20220) is a high-tensile circular insert engineered for the rigorous demands of drill collar handling. Featuring a 1/2-inch thickness profile, the 2620 is the primary gripping component for DCS-S and DCS-R slips, ensuring a non-slip mechanical lock on drill collars ranging from 4″ to 7″ OD. Manufactured from forged 8620 alloy steel, these buttons are designed to endure high-impact “setting” forces while maintaining a sharp, aggressive bite.
Description
Technical & Engineering Data
Engineered for Drill String Security
Intermediate drill collars require a button that balances penetration with pipe protection. Pan 2620 buttons deliver:
Shock-Resistant Metallurgy: Forged from high-grade alloy steel, these buttons are built to absorb the kinetic energy of “dropping the slips” under heavy strings without cracking or deformation.
Controlled Depth Carburization: Case-hardened to 58-62 HRC, the pyramid teeth are deep-hardened to ensure they don’t “round off” during extended drilling programs in abrasive formations.
Vibration Stability: Every button is precision-ground to a high-tolerance diameter, ensuring a tight “press-fit” in the slip segment pockets. This eliminates button-chatter, which is the leading cause of slip body wear.
