Sandvik Coromant 6633728 Indexable Drill Insert 880LM

Product Description

The SANDVIK COROMANT 6633728 is a solid carbide indexable drill insert designed for use in modular indexable drilling systems. Carrying the 880LM chipbreaker designation and manufacturer grade 4334, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for improved wear resistance and heat management during chip formation. The inscribed circle measures 15.45 mm (0.6083 inches), thickness is 0.1772 inches, and the corner radius is 1.00 mm (0.0394 inches). The square shape and right-hand cutting direction suit standard CNC machining center setups. Installation and replacement are handled by machinists and CNC tooling technicians.

This insert is intended for use in compatible SANDVIK COROMANT 880-series indexable drill bodies that accept the 080510 insert size with a 4.70 mm (0.1850 inch) hole diameter. The LM chipbreaker geometry is suited for light to medium feeds in steel and similar ferrous workpiece materials. Typical applications include through-hole and blind-hole drilling operations in production environments where consistent tool life and predictable chip control are required. Sold individually; minimum order quantity is 10 units.

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key as specified by the drill body manufacturer to secure the insert screw; do not substitute fastener types. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper seating and runout.
