Tool-flo 0151000AC50E On-edge Threading Insert 60V

Product Description

The TOOL-FLO 0151000AC50E is a solid carbide, on-edge threading insert designed for cutting both external and internal V-form threads on ferrous workpiece materials. Manufactured to insert style TNMA with a size code 54, this insert carries a manufacturer grade of AC50E and features a PVD-applied AlTiN coating for thermal resistance and extended tool life in production threading operations. The neutral cutting direction and neutral rake geometry suit a wide range of threading setups on CNC lathes and threading machines. The inscribed circle measures 0.625 inches and the insert thickness is 0.252 inches, with a corner radius of 0.008 inches nominal.

This insert is suited for threading cast iron and steel workpieces across a thread range of 4 to 20 TPI for both external and internal applications. The 60-degree V-form thread standard covers a broad range of unified and metric-profile threading tasks in job shop and production environments. Machinists and CNC operators working in general metalworking, toolroom, and production turning applications will find this insert applicable to both roughing and finishing thread passes within its rated TPI range.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the toolholder is properly secured before seating or replacing the insert. Verify insert orientation matches the required cutting direction before clamping. Follow toolholder manufacturer torque guidance for the clamping screw to avoid insert damage or chipping.
