Tool-flo 583812RAC3R Threading Insert 12 Tpi Flo-lock AC3R

Product Description

The TOOL-FLO 583812RAC3R is a carbide threading insert designed for precision thread cutting on both internal and external profiles. Built to the UNJ thread standard with a 60-degree included angle, this insert runs at 12 TPI and carries an AC3R grade designation, indicating a PVD-coated carbide substrate suited for demanding threading applications. The Flo-Lock series design provides secure seating and repeatable positioning in compatible toolholders. This insert is typically installed by machinists and CNC tooling technicians working in aerospace, defense, or precision manufacturing environments where UNJ thread forms are specified.

This insert handles both internal and external threading operations, making it a versatile choice when a single insert style must cover multiple thread-cutting passes. The right-hand configuration suits standard thread direction applications. Insert size 3014 and the 12 TPI pitch target medium-pitch threading on a range of workpiece materials suited to C2 and C3 carbide grades. The PVD coating extends tool life in ferrous and non-ferrous cutting conditions where heat and abrasion are factors.

Key Features

• 12 TPI internal and external pitch for versatile thread cutting on a single insert
• UNJ thread standard with 60-degree included angle for aerospace-grade thread profiles
• PVD-coated AC3R carbide grade - material grades C2 and C3 for extended wear resistance
• Right-hand cut orientation for standard threading direction
• Flo-Lock series geometry for positive insert seating and consistent tool positioning
• Insert size 3014 with a thickness of 0.1950 inches and corner radius range of 0.0125 to 0.0135 inches

Compatibility

Designed as an OEM-style replacement threading insert for TOOL-FLO Flo-Lock series toolholders accepting the FLJP insert style in size 3014.

Installation Notes

Threading inserts should be installed by qualified machinists or CNC tooling technicians following the toolholder manufacturer's clamping torque and seating procedures. Power down or disable the spindle and engage machine lockout before changing inserts. Inspect the pocket seat and clamping components for wear or debris before seating the new insert. Handle carbide inserts carefully - edge chipping from impact will affect thread quality and tool life.
