Allied Machine 11821952 Indexable Drill Insert Xcnten

Product Description

The ALLIED MACHINE AND ENGINEERING 11821952 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. Manufactured to the XCNTEN insert style with a CTCP435 grade designation, this insert features an 88-degree included angle and a square shape with a 0.031-inch corner radius. The inscribed circle measures 0.209 inches, and the insert thickness is 1.87 inches. The EN chipbreaker geometry promotes controlled chip evacuation during drilling operations. This insert is installed by machinists and tooling technicians in CNC and manual drilling applications across metalworking environments.

This insert is suited for indexable drill bodies that accept XCNTEN-style square inserts in the CTCP435 carbide grade. Typical applications include production drilling in ferrous and non-ferrous materials where consistent hole quality and insert repeatability are required. The CTCP435 grade is positioned for general-purpose carbide drilling performance. This insert is sold individually with a minimum order quantity of 10 units.
