Seco 00025628 Corner Radius End Mill 4mm 3 Flute Carbide

Product Description

The SECO 00025628 is a solid carbide corner radius end mill designed for precision milling in steel and non-ferrous metal applications. With a 4 mm cutting diameter and a 0.1 mm corner radius, it produces controlled edge geometry that reduces chipping and extends tool life in demanding roughing and finishing passes. The three-flute configuration supports efficient chip evacuation, and the MEGA coating improves wear resistance and heat management. At 14 mm length of cut and 50 mm overall length, this is a short-length tool built for rigidity and accuracy in tight-tolerance work. Licensed machinists and CNC tooling specialists are the primary installers.

This end mill is suited for CNC machining centers running steel and non-ferrous metal stock in both production and job-shop environments. The centercutting design allows plunge entry, expanding its versatility in slotting and pocket milling operations. The high helix angle promotes smooth cutting action and efficient chip removal, making it appropriate for both roughing passes and semi-finish work. The straight-cylindrical shank with h5 tolerance fits standard collet and end mill holder tooling systems.

Key Features

• 4 mm cutting diameter with 0.1 mm corner radius for controlled edge geometry
• 3-flute, right-hand spiral flute design for efficient chip evacuation
• MEGA coating for improved wear resistance in steel and non-ferrous applications
• Centercutting capable, supporting plunge and ramping entry strategies
• Short-length (14 mm LOC) design maximizes rigidity and reduces deflection
• High helix angle promotes smooth cutting and heat dissipation

Compatibility

Designed as an OEM-style replacement or direct-fitment tool for CNC machining applications requiring a 4 mm straight-cylindrical shank, compatible with standard collet chucks and end mill holders accepting h5 shank tolerance. Primary workpiece materials are steel and non-ferrous metals, per Series J36 specifications.

Installation Notes

Installation and tool changes should be performed by qualified machinists or CNC tooling technicians with the machine powered down and spindle locked. Use a calibrated torque wrench when securing collet nuts to manufacturer specifications for the holder system in use. Verify runout with a dial indicator after installation — the maximum TIR for this tool is 0.02 mm. Always follow shop safety protocols and machine guarding requirements during tool changes and test cuts.
