7″ x 6-5/8″ Slip Insert for Varco Style Slips | Part 2172
The 7″ x 6-5/8″ Slip Insert is a heavy-duty reduction insert engineered to adapt 7″ rotary and casing slips for the secure handling of 6-5/8″ OD tubulars. Designed for high-capacity Varco Style slips (such as the RSLG series), these inserts feature a specialized 5/8″ thickness profile to ensure uniform radial grip. Manufactured from high-tensile forged alloy steel and heat-treated to API 7K standards, they provide the essential mechanical bite required to support heavy drill strings and casing during high-torque makeup and breakout.
Description
Comprehensive Technical Data
Precision-Reduction Engineering
Handling 6-5/8″ tubulars within a 7″ body requires an insert that eliminates vibration while providing a fail-safe mechanical lock:
Anti-Deformation Tooth Profile: The precision-machined “bite” is calibrated to distribute radial clamping forces evenly, preventing “crushing” or stress risers on the 6-5/8″ pipe wall.
Superior Metallurgy: CNC-machined from forged 8620 alloy steel, offering a dense grain structure that resists cracking under the high-impact “setting” of the slips.
Advanced Heat Treatment: Every insert is case-hardened to 58-62 HRC, resulting in a rock-hard gripping surface for longevity and a ductile core to absorb sudden shock loads.

Equipment Compatibility
Varco Style Casing Slips: Specifically designed for RSLG (Regular Slip Long Grip) and other large-body slips requiring 5/8″ thickness reduction inserts.
Heavy Drilling Units: Ideal for rigs running 6-5/8″ drill pipe for high-torque or deep-water applications.
Global Interchangeability: Fits most major brand 7″ slips requiring 2-3/4″ length inserts for 6-5/8″ pipe.
Key Performance Advantages
Optimized Grip Consistency: Engineered to penetrate through pipe scale, rust, and heavy drilling mud for a fail-safe mechanical lock.
Precision Seating: Machined to exact tolerances to prevent “insert roll” or vibration within the slip body under extreme rotational torque.
Extended Wear Life: Superior heat-treatment prevents teeth from “rounding off” in abrasive environments, reducing rig downtime for maintenance.
Corrosion Defense: Finished with a protective industrial coating to withstand offshore salt spray and high-humidity land rig conditions.
