Seco 02685806 Indexable Face Mill 3.15 in 9 Insert R220.48

Product Description

The SECO 02685806 is an indexable chamfer angle face mill designed for high-productivity facing operations on machining centers and milling machines. It accepts 9 ON.U 09 inserts held in place by a wedge clamping method and cuts in the right-hand direction. The cutter spans a minimum cutting diameter of 3.15 inches and a maximum cutting diameter of 3.74 inches, with a maximum depth of cut of 0.236 inches. The close-pitch, 9-flute configuration supports aggressive material removal rates while maintaining surface finish quality. This tool is specified for use by machinists and tooling engineers in production and job-shop environments.

The 02685806 belongs to the SECO R220.48 series and is configured for facing applications. The 1-inch arbor hole with a 0.38-inch keyway width allows direct mounting to standard milling arbors and spindle tooling. With a maximum rated speed of 4,400 RPM and a negative rake angle of -8 degrees, this cutter is well suited for face milling steel, cast iron, and similar materials where cutting forces and insert stability are primary concerns. It is intended for horizontal and vertical milling setups in both production and maintenance-repair machining environments.

Key Features

• 9-insert close-pitch design maximizes feed rate and material removal in facing operations
• Wedge insert clamping method provides secure, repeatable insert seating under high cutting loads
• Negative rake angle (-8 degrees) increases insert edge strength for interrupted cuts and harder materials
• Maximum cutting speed of 4,400 RPM suits a wide range of machining center spindles
• 1-inch arbor hole with 0.38-inch keyway width fits standard milling arbor tooling
• No coolant-through configuration simplifies setup and toolholder compatibility

Compatibility

Designed for use with ON.U 09 series indexable inserts as part of the SECO R220.48 cutter system. Compatible insert size code is ON.U05. Fits standard 1-inch milling arbors with a 0.38-inch keyway.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per applicable lockout/tagout procedures. Confirm arbor and keyway dimensions before mounting to ensure proper fit and eliminate runout. Torque all insert wedge screws to the tool manufacturer specification found in the SECO R220.48 series tooling manual — do not estimate clamping force. Verify maximum RPM does not exceed 4,400 before programming spindle speeds.
