Description
The SECO 02685799 is an indexable chamfer angle face mill designed for high-productivity facing operations on milling machines. Built to the R220.48 series standard, it accepts 10 ON.U 09 inserts held in place by a wedge clamping method. The cutter runs in a right-hand cutting direction with a negative rake angle of -8 degrees, producing clean, flat surfaces across a range of ferrous and non-ferrous workpiece materials. With a minimum cutting diameter of 6.3 inches and a maximum cutting diameter of 6.89 inches, this shell mill is suited for wide-face passes in both production and job-shop environments. Maximum depth of cut is 0.236 inches. The unit weighs 9.7 pounds.
This face mill is intended for CNC machining centers and manual horizontal or vertical knee mills equipped with an arbor or shell mill adapter with a 2-inch arbor hole. The 40-degree chamfer angle geometry makes it well-suited for facing steel, cast iron, and similar materials where a consistent surface finish across a broad cutting path is required. With a maximum rated spindle speed of 3,100 RPM and a normal pitch insert layout across 10 flutes, it supports stable, even chip load distribution in typical production facing cycles. Coolant-through capability is not supported on this cutter body.
Key Features
- R220.48 series cutter body compatible with ON.U 09 insert size
- Wedge insert holding method for secure clamping under interrupted and continuous cuts
- 10-flute, normal pitch layout distributes chip load evenly across the face
- Negative rake angle of -8 degrees supports stable cutting in harder materials
- Maximum rated speed of 3,100 RPM suitable for standard machining center applications
- No coolant-through channels simplifies setup on standard arbor adapters
Compatibility
Designed for use with ON.U 09 series inserts and compatible with arbor or shell mill adapters with a 2-inch bore. This cutter belongs to the SECO R220.48 series platform.
Installation Notes
Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle and machine are fully powered down and locked out before mounting or removing the cutter body from the arbor adapter. Verify arbor bore fit, keyway alignment to the 0.76-inch keyway width, and draw bolt torque per the machine tool manufacturer specifications before running. Never exceed the maximum rated spindle speed of 3,100 RPM.
