Sandvik Coromant 6633712 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6633712 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drills. It features an 880LM chipbreaker geometry and a multilayer TiCN/Al2O3/TiN coating applied via the CWD process, delivering wear resistance and thermal stability during drilling operations. The square insert shape with a 0.70 mm corner radius and a 0.2913-inch inscribed circle suits right-hand cutting in ferrous and non-ferrous materials. Metalworking professionals and CNC machine operators install this insert in production drilling applications where consistent hole quality and insert life are priorities.

This insert is suited for use in industrial machining environments including production shops, job shops, and manufacturing facilities running CNC machining centers or drill presses equipped with 880-series indexable drill bodies. The LM chipbreaker is designed for light-to-medium cutting conditions. Right-hand cutting direction makes it appropriate for standard rotating-spindle setups. Insert size designation is 04P with a 7.40 mm length and width, and a 2.80 mm hole diameter for secure seating in the drill body pocket.

Compatibility

Designed as a replacement indexable drill insert for 880-series drill bodies using 04P insert size pockets with a square insert style and LM chipbreaker designation. Confirm pocket geometry and insert size against your drill body documentation before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is locked out before indexing or replacing inserts. Use the correct torx or insert-retention key specified by the drill body manufacturer to seat the insert firmly in the pocket without overtightening. Inspect the insert pocket for debris or wear before seating the new insert to ensure proper support and cutting geometry.
