Seco 03136963 Indexable Drill Insert SCGX11P1 DP2000

Product Description

The SECO 03136963 is a solid carbide indexable drill insert designed for use in Perfomax series indexable drills. It carries the SCGX11P1 geometry with a DP2000 manufacturer grade and features a Duratomic coating process applying TiCN and Al2O3 layers for extended tool life in steel cutting applications. The insert has a square shape with a 90-degree included angle, a 7-degree relief angle, and a 0.8 mm corner radius. The inscribed circle measures 0.4531 inches (insert size code 11), and the P1 chipbreaker geometry supports chip control during drilling operations. This insert is sold individually with a minimum order quantity of 10.

This insert is intended for metal-cutting professionals and machining shops running Perfomax indexable drill bodies in production or job-shop environments. It is rated for primary use on steel workpieces, corresponding to ISO material group P (P-grade, material grades C2 and C3). Typical applications include through-hole and blind-hole drilling in structural steel, mild steel, and similar ferrous materials on CNC lathes, machining centers, and drill presses where indexable tooling is preferred for repeatability and cost efficiency.

Installation Notes

Indexable drill insert replacement is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before accessing the drill body insert seats. Use the correct torx or hex key specified by the drill body manufacturer to seat the insert clamp screw to the proper feel — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and clamping screw for wear or debris before indexing or installing a new insert.
