4-1/2″ x 4-1/2″ Slip Insert for Varco Style Slips | Part 20165
The 4-1/2″ x 4-1/2″ Slip Insert (Pan P/N: 20165) is the definitive gripping solution for 4-1/2″ OD drill pipe handling. Engineered to fit Varco Style RSST (Short), RSMD (Medium), and RSLG (Long Grip) slips, these inserts are manufactured from premium forged alloy steel. Every batch is heat-treated to API 7K standards, ensuring the aggressive mechanical grip required for high-torque drilling and the vertical support needed for heavy drill strings.
Description
Comprehensive Technical Data
Rig-Floor Standard Engineering
As the most widely used insert size, our 20165 series is built for maximum service life and pipe protection:
True-Fit Circularity: Precision-machined to 1/2″ thickness, allowing the slip body to maintain perfect contact around the pipe circumference, preventing “bottlenecking” and pipe scarring.
Premium Metallurgy: CNC-machined from forged 8620 alloy steel, providing superior grain structure and impact resistance compared to standard cast parts.
Optimized Hardness: Surface hardened to 58-62 HRC. This provides a rock-hard gripping surface for secure handling, while the core remains ductile to absorb the intense shock of setting the slips.

Equipment Compatibility
Varco Style Slips: Optimized for RSST (Short), RSMD (Medium), and RSLG (Long Grip).
Drilling Slips: Compatible with SDS, SDML, and SDXL slip bodies utilizing standard 1/2″ inserts.
Global Interchangeability: Fits most major brand 4-1/2″ slips requiring 2-3/4″ length inserts.
Key Performance Advantages
Consistent Grip Profile: Specifically designed to penetrate through pipe scale and heavy drilling fluids for a reliable mechanical hold.
Precision Machining: Ensures a perfect seat in the slip body, preventing “insert roll” and uneven pipe loading.
Extended Service Life: High-hardness tooth profile resists “rounding off” under high-frequency use.
Corrosion Protection: Finished with a protective industrial coating to withstand offshore salt spray and high-humidity rig environments.
