Sandvik Coromant 6626839 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6626839 is a solid carbide indexable drill insert designed for use with compatible 880-series indexable drills. This insert features an LM chipbreaker geometry and a 4324 manufacturer grade coating — a TiCN plus Al2O3 multilayer finish applied via a CWD coating process — providing wear resistance and thermal stability during drilling operations. The inscribed circle measures 10.65 mm (0.4193 inches) with a square shape, a corner radius of 0.80 mm (0.0315 inches), and a thickness of 0.1378 inches. Right-hand cutting direction is standard. It is sold individually with a minimum order quantity of 10 units.

This insert is suited for industrial metal-cutting applications where precise hole-making is required. The 880LM insert style is commonly used in production drilling environments — including aerospace, automotive, and general machining shops — where controlled chip formation and consistent tool life are priorities. The solid carbide substrate combined with the TiCN and Al2O3 coating makes it appropriate for drilling steel, cast iron, and similar ferrous workpiece materials. Installation is handled by CNC machinists and toolroom technicians.

Installation Notes

Insert replacement is performed by CNC machinists or toolroom technicians with the machine powered down and spindle locked. Use a calibrated torque wrench and the manufacturer-specified Torx or hex key to secure the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Follow the toolholder manufacturer's service documentation for correct seating procedure.
