5″ x 4-1/2″ Slip Insert for Varco Style Slips | Part 20166
The 5″ x 4-1/2″ Slip Insert (Pan P/N: 20166) is a premium reduction insert engineered for the secure handling of 4-1/2″ OD drill pipe within a 5″ slip body. Designed for Varco Style RSMD (Medium) and RSLG (Long Grip) slips, these inserts provide a multi-point, non-slip hold essential for high-torque drilling. Manufactured from high-grade alloy steel and precision-hardened to API 7K standards, they protect your tubular assets from damage while ensuring rig floor safety.
Description
Comprehensive Technical Data
Advanced Metallurgical Engineering
In the fast-paced environment of the rig floor, a secure grip is non-negotiable. Our 20166 series is built to outperform standard inserts:
Specialized Carburization: Undergoes a meticulous heat-treating and carburization process to achieve exceptional surface hardness (58-62 HRC). This ensures the teeth maintain a sharp biting edge through thousands of connections.
Uniform Load Distribution: Precision-machined to a 3/4″ thickness profile, ensuring the slip assembly provides consistent radial pressure to prevent “bottlenecking” or crushing of the 4-1/2″ pipe.
Shock-Resistant Core: While the surface is rock-hard, the inner core remains ductile to absorb the intense impact of “setting the slips” under the weight of a heavy drill string.

Equipment Compatibility
Varco Style Slips: Specifically designed for Regular Slip Medium (RSMD) and Regular Slip Long Grip (RSLG).
Drilling Slips: Compatible with SDML and SDXL slip bodies utilizing 3/4″ thickness reduction inserts.
Universal Rig Fit: Fits most major brand 5″ slips requiring 2-3/4″ length inserts for 4-1/2″ pipe.
Key Performance Advantages
Aggressive Mechanical Bite: Designed to penetrate through thick drilling mud and pipe scale to ensure a fail-safe mechanical lock.
Enhanced Pipe Protection: The tooth geometry is optimized to provide maximum grip with controlled penetration, reducing the risk of deep scarring on the drill rod.
Precision Seating: CNC-machined to exact tolerances to prevent “insert roll” or vibration within the slip body during high-torque operations.
Corrosion Defense: Treated with an industrial-grade coating to resist oxidation in offshore and high-humidity environments.
