Seco 02422255 Indexable Face Mill 1.97in 45 Degree 5 Flute

Product Description

The SECO 02422255 is a 45-degree indexable chamfer angle face mill designed for precision facing operations on machining centers and milling machines. Built to Series R220.53 specifications, it accepts SE 09T3 inserts held by screw-lock mounting and delivers a right-hand cut across five flutes. The minimum cutting diameter is 1.97 inches and the maximum cutting diameter is 2.36 inches, with a maximum depth of cut of 0.18 inches. Through-coolant capability keeps cutting temperatures in check during high-feed facing passes. At 1.3 pounds, the body is compact enough for close-tolerance work while the negative radial and positive axial rake geometry optimizes chip formation on a wide range of workpiece materials.

This face mill is suited for flat surface generation and chamfer-facing applications in job shop and production environments. The 3/4-inch arbor hole and 8.20 mm keyway width allow secure mounting to standard arbors and milling spindles. With a maximum rated speed of 15,800 RPM, it performs well on both conventional knee mills and high-speed CNC machining centers. Licensed machinists and toolroom technicians are the primary installers. The R220.53 series is a well-established SECO platform for normal-pitch, multi-insert facing work on steel, cast iron, and aluminum workpieces.

Key Features

• 45-degree chamfer angle geometry reduces entry forces and minimizes edge chipping on interrupted cuts
• Five-insert, five-flute configuration delivers high metal removal rates in facing applications
• Through-coolant design directs fluid directly to the cutting zone for improved tool life and chip evacuation
• SE 09T3 insert compatibility with screw-lock retention for quick, repeatable indexing
• Negative radial and positive axial rake balances cutting force with chip control across common workpiece materials
• Maximum 15,800 RPM rating supports high-speed machining center use

Compatibility

Designed for use with SE 09T3 inserts on standard 3/4-inch arbor spindle configurations. Part of the SECO R220.53 series indexable face mill platform.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered off and the spindle fully locked out per facility lockout/tagout procedures. Verify arbor hole fit and keyway alignment before torquing the retention screw to the spindle arbor. Inserts should be seated and screw-locked according to the insert manufacturer torque specification. Confirm coolant-through passages are clear and unobstructed before running the cutter at speed.
