Carmex 27UIR3ACMEP25C Laydown Threading Insert 3 Tpi

Product Description

The CARMEX 27UIR3ACMEP25C is a solid carbide laydown threading insert designed for internal Acme thread cutting at 3 threads per inch (TPI). Built to the Acme thread standard, this insert features a 5/8 inch inscribed circle and a thickness of 0.251 inches. The P25C manufacturer grade with C5 material grade and PVD-applied TiN coating supports consistent performance across a wide range of workpiece materials. It is used in CNC lathes and threading applications by machinists and toolroom professionals working in metalworking shops and manufacturing environments.

This insert is suited for internal right-hand and left-hand Acme thread profiles. The 60-degree included angle and laydown seating geometry position it for use in production threading operations on a broad range of materials, including steel, stainless, cast iron, non-ferrous metals, high-temp alloys, and other universal workpiece classifications. It is sold individually but carries a minimum order quantity of 10 units per order.

Installation Notes

Installation is performed by qualified machinists following standard CNC toolholder insert seating procedures. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to secure the insert without over-torquing the clamping screw. Verify insert seating and clearance angles before resuming cutting operations.
