7-5/8″ x 9-5/8″ Slip Insert for Varco Style Slips | Part 2633
The 7-5/8″ x 9-5/8″ Slip Insert is a high-tensile gripping component specifically engineered for large-diameter casing operations. Designed for use in Varco Style Casing Slips, these inserts provide the aggressive mechanical bite required to hold 9-5/8″ OD casing strings securely in the rotary table. Manufactured from forged alloy steel and heat-treated to API 7K specifications, they ensure maximum rig floor safety and tubular protection.
Description
Comprehensive Technical Data
Heavy-Duty Casing Engineering
Handling 9-5/8″ casing requires an insert that can withstand immense radial compression while maintaining a non-slip grip:
Anti-Deformation Tooth Profile: The precision-machined tooth pattern is designed to provide maximum surface contact, distributing the load evenly to prevent “bottlenecking” or crushing of the casing wall.
Superior Metallurgy: CNC-machined from forged 8620 alloy steel, offering a superior grain structure and impact resistance compared to cast alternatives.
Specialized Case-Hardening: Surface hardened to 58-62 HRC. This ensures the biting edges remain sharp under thousands of tons of vertical pressure, while the inner core stays ductile to absorb shock loads.

Equipment Compatibility
Varco Style Casing Slips: Optimized for CMS-XL and other extra-long casing slip bodies requiring 1-1/2″ width inserts.
Heavy Drilling Units: Critical for intermediate casing runs on deep-water and high-pressure land rigs.
Global Interchangeability: Fits most major brand 9-5/8″ casing slip assemblies requiring 2-3/4″ length inserts.
Key Performance Advantages
Optimized Friction Coefficient: Designed to penetrate through thick drilling fluids, rust, and pipe scale for a fail-safe mechanical lock.
Precision Seating: Machined to exact tolerances to prevent “insert roll” within the slip body under high-torque conditions.
Extended Wear Life: High-hardness surface resists “rounding off,” significantly reducing the frequency of insert changes during long casing runs.
Corrosion Protection: Finished with a protective industrial coating to withstand offshore salt spray and high-humidity environments.
