Tool-flo 5006614AC22A Threading Insert 14 Tpi 3/8 in Ic

Product Description

The TOOL-FLO 5006614AC22A is a solid carbide laydown threading insert designed for external UN thread cutting at 14 threads per inch (TPI). Manufactured in the 16ER insert style with a right-hand cutting orientation, it carries an AlTiN coating applied via PVD process, which provides elevated heat resistance and extended tool life in high-speed threading operations. The 3/8 inch inscribed circle (IC) sizing positions this insert for use on standard threading toolholders accepting the 16ER form factor. Licensed machinists and CNC lathe operators working in production or job-shop environments are the primary users of this insert.

This insert is suited for external threading on ferrous and non-ferrous workpieces where UN thread standards are required. The right-hand configuration addresses the most common lathe threading direction in standard machining setups. Its solid carbide substrate and PVD-applied AlTiN finish make it appropriate for dry cutting or minimal-coolant operations at elevated cutting speeds, particularly on lathes programmed for single-point threading passes on precision components.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading applications
• AlTiN coating via PVD process for improved heat resistance and extended insert life
• 14 TPI UN external thread profile, right-hand cut
• 16ER insert style with 3/8 inch inscribed circle
• Chipbreaker (CB) geometry to manage chip flow during threading passes
• Cutting edge to theoretical edge length of 0.050 inches; face of insert to tip centerline of 0.060 inches

Compatibility

Designed as a replacement or production-run insert for toolholders accepting the 16ER laydown threading insert style. Confirm toolholder seat geometry and insert style code before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or hex key to the toolholder manufacturer's recommended procedure when clamping the insert - do not overtighten the clamping screw. Verify thread profile and pitch alignment with a thread gauge after the first test pass before committing to a full production run.
