Seco 02642879 Square-shoulder Face Mill 3 Inch 5 Insert

Product Description

The SECO 02642879 is an indexable square-shoulder face mill designed for precision slotting and shoulder milling operations in metalworking environments. Built around the Square 6 series platform and styled as the R220.96 cutter, it accepts five XNEX 0806 inserts held by clamp and screw, producing a clean 90-degree lead angle on every pass. The cutter spans a 3-inch maximum cutting diameter with a 1-inch arbor hole and delivers a maximum depth of cut of 0.295 inches. Through-coolant capability helps manage chip evacuation and heat at the cutting zone. This tool is installed by machinists and tooling technicians working on CNC mills and manual milling machines in production and job-shop settings.

The 02642879 is suited for square-shoulder facing, slotting, and step milling on steel, cast iron, and similar materials where a 90-degree wall is required. Its coarse pitch, five-flute layout supports stable cutting in interrupted cuts and moderate material removal applications. The right-hand cutting direction and negative rake geometry are matched to the XNEX 0806 insert family. Overall tool height of 1.97 inches and a hub diameter of 62 mm (approximately 2.44 inches) fit standard arbor setups used across general metalworking operations.
