Tool-flo 13495AC54F Laydown Threading Insert 5 Tpi Api

Product Description

The TOOL-FLO 13495AC54F is a solid carbide laydown threading insert designed for cutting API-standard threads in demanding machining applications. Built to the LDS 54 insert style with an AC54 manufacturer grade, this insert carries a PVD-applied AlTiN coating that improves heat resistance and tool life when threading cast iron and steel workpieces. It cuts at 5 threads per inch with a 60-degree included angle and is configured for right-hand internal and external threading. The 5/8-inch inscribed circle and 1/4-inch thickness conform to standard LDS 54 insert geometry, making it a direct fit for compatible laydown threading toolholders used in oil-field and precision machining environments.

This insert is suited for threading operations on API-spec components such as pipe, coupling, and tool-joint profiles common in oil and gas production. It handles both external and internal thread forms in a single insert style, which reduces tooling changeover time on CNC lathes and turning centers. Primary workpiece materials are cast iron and steel. Licensed machinists, tooling specialists, and CNC operators working to API thread standards are the typical end users for this insert.

Key Features

• Solid carbide substrate with PVD AlTiN coating for extended tool life in steel and cast iron
• 5 TPI cutting geometry with 60-degree included angle for API thread profiles
• Right-hand configuration supports both internal and external threading
• 5/8-inch inscribed circle, LDS 54 insert style for laydown toolholder compatibility
• 0.0200-inch corner radius and 0.2500-inch hole diameter for precise seating and repeatability
• Chipbreaker style A for controlled chip evacuation during threading passes

Compatibility

Designed for use in LDS 54-series laydown threading toolholders that accept the LDS 54 insert style with a 5/8-inch inscribed circle and 1/4-inch thickness. Suitable for machining API-standard thread profiles on cast iron and steel workpieces.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer torque and clamping specifications. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before changing inserts. Confirm insert orientation matches the intended right-hand thread direction before commencing a threading cycle. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
