Kennametal 4090567 Solid Carbide Keyway End Mill 3 Flute

Product Description

The KENNAMETAL 4090567 is a solid carbide keyway end mill designed for precision milling in tight tolerances and demanding cutting applications. It carries a 0.1102-inch mill diameter, a 3-flute spiral flute configuration, and an AlTiN (aluminum titanium nitride) finish that improves heat resistance and tool life in ferrous and hardened materials. With a 38-degree helix angle and centercutting geometry, this end mill handles both plunge and peripheral milling operations. It belongs to the KENNAMETAL F3AU series and is intended for use by machinists and toolroom professionals working on CNC machining centers and manual milling machines.

This end mill is suited for keyway slotting, profiling, and light contouring in steel, stainless steel, and similar materials where a small-diameter, high-performance carbide tool is required. The 12mm length of cut (LOC), 6mm shank diameter, and 50mm overall length make it appropriate for shallow keyway operations and slot milling on small workpieces or in confined features. The AlTiN coating supports dry or near-dry machining environments common in production shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN finish improves thermal resistance and extends tool life at elevated cutting temperatures
• 38-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge entry into the workpiece
• 3-flute spiral design balances material removal rate with chip clearance
• F3AU series construction for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual milling machines accepting a 6mm shank diameter tool holder.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist familiar with proper tool holder torque procedures and speeds-and-feeds selection for carbide tooling. Ensure the tool holder collet or chuck is clean and free of runout before seating the 6mm shank. Confirm spindle RPM and feed rate are appropriate for the workpiece material and 0.1102-inch diameter before engaging the cut. Never exceed the rated depth of cut for the listed 12mm LOC.
