Seco 03083964 Square End Mill 0.2362in 4-flute Carbide Altin

Product Description

The SECO 03083964 is a single-end square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding cuts. The tool features a 0.2362 inch (6.00 mm) cutting diameter, a 0.7087 inch (18.00 mm) length of cut, and a 0.2362 inch (6.00 mm) shank diameter. An AlTiN coating provides thermal resistance for high-speed and dry machining environments. The variable helix design helps break up harmonic vibration during cut, improving surface finish and tool life. Machinists and CNC operators working in job shops, aerospace, or general metalworking will install this tool in standard collet or end mill holders.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a long flute length and centercut geometry are required. The right-hand cut, right-hand helical flute geometry provides efficient chip evacuation in climb and conventional milling setups. The long flute length classification makes it appropriate for applications requiring deeper axial engagement or step-down operations that a standard-length end mill cannot reach. It belongs to the SECO STR440M.2 series.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• AlTiN coating for thermal resistance in high-speed and dry cutting
• Variable helix design reduces harmonic vibration and chatter
• Centercutting geometry allows plunge entry
• Long flute length (0.7087 inches) for deeper axial engagement
• Right-hand cut with right-hand helical flutes for standard spindle rotation

Compatibility

Part of the SECO STR440M.2 series. Fits standard 6.00 mm (0.2362 inch) collet chucks, shrink-fit holders, and end mill holders compatible with a 0.2362 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading any cutting tool. Seat the shank fully into the holder to the recommended gauge line and torque the collet nut or set screw per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to avoid premature edge wear.
