Iscar 5997713 Threading Insert 10 Tpi Acme IC250 Carbide

Product Description

The ISCAR 5997713 is a solid carbide laydown threading insert designed for cutting external Acme threads in demanding machining applications. Carrying the IC250 manufacturer grade with a PVD-applied TiCN/TiN coating, this insert delivers consistent thread form accuracy and wear resistance on difficult workpiece materials. It produces a 10 TPI Acme thread profile and is sized with a 3/8 inch (0.375 inch) inscribed circle and a thickness of 0.143 inches. The right-hand cutting geometry suits standard lathe setups running external threading passes. This insert is part of the ISCARTHREAD series and is used by machinists and toolroom professionals on CNC and manual turning centers.

This insert is intended for external Acme thread turning on cast iron, stainless steel, and steel workpieces, covering primary workpiece material codes K, M, and P. It is suited to applications where Acme thread profiles are required, such as lead screws, power screws, and actuator components. The 10 TPI pitch and right-hand orientation match standard Acme thread specifications. It fits into compatible 16ER-style insert pockets on threading toolholders designed for the 16ER insert size code.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or toolroom technicians. Power down and lock out the turning center before changing inserts. Seat the insert fully in the pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert pocket for chips or damage before seating a new insert to ensure proper thread form accuracy.
