Parlec T111615TTP Boring Insert Tcmt Triangle Carbide

Product Description

The PARLEC T111615TTP is a TCMT-style solid carbide boring insert designed for precision metal cutting on CNC and manual boring operations. The insert features a 60-degree triangular shape with a positive rake geometry and a P-style chipbreaker, promoting efficient chip evacuation during through-hole and blind-hole boring. A TiN/TiC/TiN multilayer coating provides wear resistance and thermal stability at elevated cutting speeds. With a 0.25-inch inscribed circle and 0.016-inch corner radius, this insert suits finish and semi-finish boring passes where dimensional accuracy matters. Screw-style insert holding keeps the insert securely indexed in compatible toolholders.

This insert is suited for boring applications in steel and stainless steel workpieces, corresponding to ISO material groups P and M. Typical use cases include CNC turning centers and boring bars where TCMT inserts are specified. The positive rake geometry reduces cutting forces, making it a practical choice for medium-to-light cuts on both hardened and standard steels. It is installed and used by machinists, toolroom technicians, and CNC operators in precision manufacturing, job shop, and production environments.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper contact and secure holding.
