Tool-flo 10495AC22A Laydown Threading Insert 4 Tpi

Product Description

The TOOL-FLO 10495AC22A is a solid carbide laydown threading insert designed for cutting API Rotary Shoulder Connection threads on a wide range of workpiece materials. Built to the LDS54 insert style with grade AC22A carbide and a PVD-applied AlTiN coating, this insert delivers consistent thread form at 4 threads per inch with a 60-degree included angle. The 5/8-inch inscribed circle and 0.252-inch thickness conform to the LDS54 series geometry. It is suited for use by machining professionals running CNC lathes and threading operations in oilfield component manufacturing and precision machining shops.

This insert handles both internal and external API Rotary Shoulder Connection threading operations, making it a versatile option across a single tool setup. The AlTiN coating supports performance across a broad range of workpiece materials, including steel, stainless, high-temp alloys, cast iron, non-ferrous metals, and hardened materials corresponding to material codes H, K, M, N, P, and S. Typical applications include threading drill collar connections, subs, and other oilfield tubular components where API thread form accuracy is required.

Key Features

• Solid carbide construction with PVD-applied AlTiN coating for extended tool life across diverse materials
• 4 TPI thread pitch with 60-degree included angle for API Rotary Shoulder Connection thread form
• Handles both internal and external threading in a single insert style
• LDS54 laydown series geometry with 5/8-inch inscribed circle and 0.252-inch thickness
• 2 teeth per side for multiple indexing positions per insert
• Universal material compatibility across H, K, M, N, P, and S workpiece material codes

Compatibility

Designed for use in toolholders accepting the LDS54 laydown insert style. Suitable for machining API Rotary Shoulder Connection threads on both internal and external configurations across universal workpiece material categories.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked. Seat the insert firmly into the toolholder pocket and verify clamp torque per the toolholder manufacturer specification before running. Inspect the thread form with a calibrated API thread gauge after the first pass to confirm profile accuracy before committing to full production runs.
