Seco 00086840 Indexable Face Mill 3.15 in 6 Insert R220.43

Product Description

The SECO 00086840 is an indexable chamfer angle face mill designed for precision facing operations in metalworking and machining environments. Built to the R220.43 series standard, it accepts six OF 05T305 inserts secured by screw-holding and delivers a positive rake geometry for reduced cutting forces and cleaner surface finishes. The minimum cutting diameter is 3.15 inches, with a maximum cutting diameter of 3.62 inches, and a maximum depth of cut of 0.138 inches. The 1-inch arbor hole provides a rigid, repeatable mount on standard horizontal and vertical machining centers. This tool is installed and operated by machinists and CNC tooling technicians in job shop and production environments.

This face mill is intended for facing applications on ferrous and non-ferrous workpieces where a chamfer angle geometry improves insert engagement and surface finish. The right-hand cutting direction suits standard spindle rotation on most vertical machining centers and mills. With a normal pitch configuration and six flutes, the tool balances feed rate capability with chip clearance across a maximum spindle speed of 9,400 RPM. It is a practical choice for shops running medium to large-diameter face milling passes in a single setup.

Key Features

• R220.43 series indexable chamfer angle design for consistent insert indexing and repeatable facing results
• Accepts six OF 05T305 inserts with screw holding for secure, vibration-resistant clamping
• Positive rake geometry reduces cutting forces and heat generation at the insert edge
• Maximum spindle speed of 9,400 RPM supports high-productivity facing passes
• Right-hand cutting direction compatible with standard CNC spindle rotation
• No coolant-through design simplifies setup on machines without high-pressure coolant delivery

Compatibility

Designed as an OEM-style indexable face mill for use with OF 05T305 inserts in the R220.43 series cutter platform. Fits machines with a 1-inch arbor and a 0.38-inch keyway width.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is locked out before mounting or removing the cutter body. Verify arbor and keyway dimensions before mounting to confirm a proper fit. Torque insert screws according to the insert manufacturer's specification using the appropriate Torx or hex key driver.
