Tool-flo 32394AC50D Threading Insert Api Round 0.5in Ic

Product Description

The TOOL-FLO 32394AC50D is a solid carbide, on-edge threading insert designed for external API Round thread profiles. Built to TNMA insert style geometry, it features a neutral cutting direction and a 0.5-inch inscribed circle (IC) with a thickness of 0.189 inches. The AlTiN coating is applied via PVD process, providing thermal resistance and extended tool life in demanding threading operations. This insert is used by machinists and tool-room professionals working on oil field tubular goods and pipe connections that require API Round thread form compliance. Manufacturer grade AC50D indicates the carbide substrate and coating combination suited for steel and alloy threading applications.

This insert is suited for external threading operations on pipe, couplings, and tubular components conforming to the API Round thread standard. It fits on-edge insert toolholders accepting TNMA-style geometry with a 0.5-inch IC. Applications include production threading of oil country tubular goods (OCTG), where consistent thread form accuracy and insert durability are critical. A cylindrical hole design provides secure clamping in compatible toolholding systems. Typical environments include CNC lathes and turning centers in pipe manufacturing and machining job shops.

Key Features

• API Round external thread form for oil country tubular goods compliance
• Solid carbide substrate with AC50D manufacturer grade for wear resistance in steel threading
• AlTiN coating via PVD process for thermal stability and extended insert life
• Neutral cutting direction compatible with standard on-edge TNMA toolholders
• Cylindrical mounting hole for positive, secure clamping in the toolholder pocket
• 0.5-inch IC and 0.189-inch thickness for precise fitment in TNMA size 43 insert seats

Compatibility

Designed for use in on-edge threading toolholders accepting TNMA insert style with a size code of 43 and a 0.5-inch inscribed circle. Confirm toolholder pocket specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the insert; do not overtighten the clamping screw. Inspect the insert seat for chips or debris before installation to ensure proper seating and thread form accuracy.
