Seco 02427189 High-feed Face Mill 2.28-3 in 6 Insert

Product Description

The SECO 02427189 is an indexable high-feed face mill designed for aggressive material removal in CNC machining operations. Built on the R220.21 cutter platform, it accepts six 218.19-160 indexable inserts secured by screw-clamp retention. The cutting diameter ranges from 2.28 to 3 inches with a maximum depth of cut of 0.1 inches and a maximum spindle speed of 10,200 RPM. The 1-inch arbor hole mounts directly to standard arbor tooling. At 1.87 pounds, the body is compact enough for a range of vertical and horizontal machining center setups. Right-hand cutting direction is standard. This tool is specified and installed by machinists, toolroom technicians, and CNC setup personnel.

The 02427189 is suited for face milling, helical interpolation, plunging, ramping, and slotting operations on machining centers. The high-feed geometry is optimized for shallow axial depths combined with high table feed rates, reducing cycle time on roughing and semi-finishing passes. The 0.39-degree maximum ramping angle supports controlled ramp entry into workpiece material. A 0.38-inch keyway width provides positive rotational drive engagement with the arbor. Coolant-through capability is not available on this model; external flood or mist coolant should be directed to the cutting zone.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per OSHA lockout/tagout procedures. Confirm arbor runout is within tool manufacturer tolerances before operation. Insert seating surfaces and screw threads should be cleaned and inspected before each insert index. Do not exceed the published maximum RPM of 10,200 for this cutter body.
