Kennametal 2400680 Square-shoulder Face Mill 2 in

Product Description

The KENNAMETAL 2400680 is an indexable square-shoulder face mill designed for precision milling operations on machining centers and milling machines. Built to the KSSP series standard, it accepts 12 SD.T 43.. style inserts secured by screw clamping for positive, repeatable insert location. The 0/90-degree lead angle produces true square shoulders, making it well-suited for step milling, shoulder milling, and facing operations where a 90-degree wall is required. Right-hand cutting direction and through-coolant capability support extended tool life in production environments. The body weighs approximately 1.89 pounds, a manageable mass for standard arbor setups.

This face mill is used in job shop and production machining environments for ferrous and non-ferrous workpiece materials requiring clean square-shoulder profiles. The 2-inch maximum cutting diameter and 1.69-inch maximum depth of cut make it appropriate for moderate-volume face milling passes on vertical machining centers and horizontal milling setups. The 3/4-inch arbor hole with an 8.41mm keyway width ensures positive drive engagement on standard arbors. Through-coolant delivery directs fluid directly to the cutting zone, reducing heat buildup during longer-duration cuts.

Key Features

• 0/90-degree lead angle for true square-shoulder and step-milling profiles
• 12-insert capacity with screw-held SD.T 43.. style inserts for rigid, accurate seating
• Through-coolant delivery for thermal management at the cutting zone
• Right-hand cutting direction; compatible with standard right-hand spindle setups
• 3/4-inch arbor hole with keyway for positive rotational drive
• KSSP series body construction for consistent insert geometry and repeatability

Compatibility

Designed for use with SD.T 43.. series indexable inserts. Arbor hole diameter of 3/4 inch fits standard arbors of that bore size. Consult insert manufacturer documentation to confirm insert grade and geometry selection for specific workpiece materials.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated. Confirm arbor and keyway dimensions match before mounting. Insert seating screws should be tightened to the torque specification published in the KENNAMETAL tooling documentation for SD.T 43.. inserts - do not use estimated values. Verify through-coolant port alignment with the machine spindle coolant supply before initiating a cut.
