Tool-flo 0153000AC50E On-edge Threading Insert 60V

Product Description

The TOOL-FLO 0153000AC50E is a solid carbide on-edge threading insert designed for cutting both external and internal 60-degree V-form threads. Coated with AlTiN via a PVD process, this insert handles a thread range of 4 to 20 TPI and features a neutral cutting direction with a neutral rake geometry. The 0.625-inch inscribed circle and 0.250-inch thickness provide the structural rigidity needed for consistent thread form across moderate to high-demand turning operations. It is installed by CNC machinists and toolroom operators working on lathes equipped with compatible on-edge threading toolholders.

This insert is suited for threading operations on cast iron and steel workpieces in both production and job-shop environments. The TNMC insert style and size code 54 designation place it in standard on-edge toolholder systems. The 4-20 TPI range covers a wide band of common fastener and fitting thread pitches, making it a practical choice for shops producing threaded components in steel or cast iron across general machining, fluid power, and industrial manufacturing applications.

Key Features

• Cuts both external and internal 60-degree V-form threads in a single insert style
• AlTiN coating applied via PVD process for heat resistance and extended tool life on ferrous materials
• Solid carbide substrate in manufacturer grade AC50E for toughness and wear resistance
• Neutral hand cutting direction suits standard lathe setups without handedness constraints
• Thread range of 4 to 20 TPI covers a broad spectrum of common thread pitches
• TNMC insert style with 0.625-inch inscribed circle fits standard on-edge threading toolholders

Compatibility

Designed for use in on-edge threading toolholder systems accepting TNMC-style inserts with a size code 54 designation and a 0.625-inch inscribed circle. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the lathe spindle is fully stopped and all power is isolated before seating or replacing the insert. Secure the insert clamp to the toolholder per the toolholder manufacturer torque guidance and verify the insert is fully seated before resuming cutting operations. Inspect the insert edge condition regularly, as AlTiN-coated carbide inserts can exhibit micro-chipping that is not always visible without magnification.
