Tool-flo 09495AC22F Threading Insert 5/8 Inch Ic 4 Tpi

Product Description

The TOOL-FLO 09495AC22F is a solid carbide laydown threading insert designed for cutting API Rotary Shoulder Connection threads on both internal and external workpieces. Manufactured from micrograin carbide and finished with an AlTiN coating applied via PVD process, this insert delivers hard, heat-resistant cutting edges suited for demanding threading operations in oil and gas component manufacturing. It carries the AC22F manufacturer grade designation, features a 5/8-inch inscribed circle, and measures 0.252 inches thick. With 2 teeth per side and a pitch of 4 threads per inch, it is built for consistent thread form accuracy on rotary shoulder profiles.

This insert is applied in precision CNC threading operations targeting API Rotary Shoulder Connection profiles, a thread standard commonly found on drill collars, subs, and other downhole tool components. The LDS54 insert style is a laydown configuration, meaning it seats flat against the holder pocket for stable clamping during high-load threading passes. It is suited for machining centers and lathes in industrial, energy-sector, and oilfield equipment manufacturing environments where API thread form accuracy is critical.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in threading applications
• AlTiN coating via PVD process provides heat resistance and extended tool life at elevated cutting temperatures
• Cuts 4 TPI API Rotary Shoulder Connection threads, both internal and external
• LDS54 laydown insert style seats flat in the pocket for stable, repeatable clamping
• 5/8-inch inscribed circle and 0.252-inch thickness per insert style geometry
• 2 teeth per side for indexable use and consistent thread form per edge

Compatibility

Designed for use in toolholders accepting the LDS54 laydown insert style. Confirm pocket dimensions and seating geometry against the holder specification before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and flat in the pocket before tightening the clamping screw to the holder manufacturer's specified torque. Inspect the insert pocket and clamping components for chips or wear before each use to ensure correct seating and thread form accuracy.
