Kennametal 6415928 Square End Mill 1mm 3 Flute Carbide

Product Description

The KENNAMETAL 6415928 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 1 mm cutting diameter and a 2 mm length of cut, this tool is built for small-diameter work requiring tight tolerances and consistent material removal. The three-flute geometry balances chip evacuation with rigidity, and the AlTiN coating provides thermal resistance and extended tool life in ferrous and hardened materials. The 30-degree helix angle promotes smooth cutting action and reduced deflection. This end mill is typically installed and operated by machinists and CNC programmers working on precision components.

This end mill suits applications in aerospace, die and mold, and general precision machining where small-diameter profiling, slotting, and peripheral milling are required. The 3 mm straight cylindrical shank fits standard collet chucks and tool holders common to CNC machining centers and high-speed spindles. Extended reach geometry allows access to deeper features without tool holder interference. The single-end configuration and right-hand flute direction make it compatible with conventional right-hand spindle setups.

Key Features

• 1 mm cutting diameter with 2 mm length of cut for small-feature precision work
• Three-flute design balances chip clearance and core strength
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 30-degree helix angle for smooth cutting action and reduced vibration
• Center-cutting capability allows plunge entry
• Solid carbide construction in KCPM15 grade for hardness and wear resistance
• Extended reach design for access to deeper workpiece features

Compatibility

Designed for use in CNC machining centers and high-speed milling spindles with standard collet or precision tool holders accepting a 3 mm straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within the collet or tool holder to the manufacturer-recommended engagement depth before tightening. Verify spindle direction is set to right-hand rotation before operation. Inspect the cutting edges for chips or coating damage prior to each use, and never exceed the tool's rated depth of cut for the material being machined.
