Sandvik Coromant 6626831 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6626831 is a solid carbide indexable drill insert designed for use with the 880 insert drill platform. It carries the 4324 manufacturer grade and features a TiCN plus Al2O3 coating applied via the CWD coating process, delivering wear resistance and thermal stability during drilling operations. The square insert shape has an inscribed circle of 0.2913 inches (7.40 mm), a thickness of 0.1102 inches, and a corner radius of 0.0276 inches (0.70 mm). The LM chipbreaker geometry is engineered to control chip evacuation in a range of workpiece materials. This insert is installed by machinists and toolroom technicians working with indexable drill tooling systems.

This insert is intended for use in production drilling applications where consistent chip control and dimensional accuracy are required. The right-hand cutting direction and square shape suit it for through-hole and blind-hole drilling on CNC machining centers and lathes equipped with the 880-series drill body. The 04P insert size classification corresponds to a specific seat pocket geometry on compatible drill bodies. Typical applications include metal removal in steel, stainless, and similar materials where a TiCN and Al2O3 coated carbide grade performs reliably.

Key Features

Compatibility

Designed as an OEM-specification replacement insert for the Sandvik Coromant 880 series indexable drill platform using the 04P insert seat geometry.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the drill body removed from the spindle and the machine powered down. Use the correct Torx key to the torque range specified by the drill body manufacturer for the 880-series clamping screw. Inspect the insert pocket for debris or damage before seating the new insert. Handle solid carbide inserts carefully to avoid chipping the cutting edges prior to use.
