Seco 00086839 Indexable Face Mill 2.48in 5 Flute

Product Description

The SECO 00086839 is an indexable chamfer angle face mill designed for precision facing operations in metalworking and machining environments. Part of the R220.43 series, this cutter accepts OF 05T305 inserts secured by screw-held positive rake seats for consistent, repeatable cuts. It features a right-hand cutting direction and accommodates 5 inserts across 5 flutes. The minimum cutting diameter is 2.48 inches, with a maximum cutting diameter of 2.95 inches and a maximum depth of cut of 0.138 inches. This tool is installed and operated by machinists and tooling specialists working on CNC and manual milling platforms.

This face mill is suited for facing operations on flat surfaces in both production and job-shop environments. The R220.43 series geometry supports efficient chip evacuation and stable insert engagement across a range of workpiece materials. With a 3/4 inch arbor hole and a standard keyway, it mounts directly to arbors and milling spindles configured for that bore size. It is appropriate for use on knee mills, horizontal mills, and CNC machining centers where facing, chamfering, and light profiling are required. No coolant-through capability is present on this body.
