Seco 74004537 Chamfer Milling Tip 0.394 in 2 Flute Carbide

Product Description

The SECO 74004537 is a replaceable chamfer milling tip designed for use with Minimaster MM10 series modular end mill systems. Built from solid carbide with a TiAlN coating applied via PVD process, this tip delivers consistent performance in demanding metal-removal applications. It features a 120-degree included angle and a 60-degree chamfer lead angle, making it well suited for chamfering, center drilling, and spot drilling operations. The cutting diameter measures 0.394 inches, maximum depth of cut is 0.106 inches, and functional length is 0.465 inches. Two flutes with an M03 chipbreaker geometry support efficient chip evacuation across a range of workpiece materials.

This tip is intended for use in CNC machining centers and milling applications where consistent chamfer geometry and repeatable indexing are required. It targets production environments handling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The right-hand cut orientation and MM10 interface make it a direct fit for Minimaster-compatible tooling bodies. No coolant-through capability is present, so external coolant or air blast should be planned accordingly. Material grade C5 aligns this tip with general-purpose and finishing operations across the listed workpiece categories.

Compatibility

Designed for use with Minimaster MM10 series modular milling toolholders. Insert size designation is 0.394-C120. Full tip description per manufacturer is MM10-0.394-C120-M03.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Follow the Minimaster system torque and seating procedures specified in the toolholder documentation for the MM10 interface. Inspect the tip seat and locking mechanism for wear or debris before installing a new tip. No coolant-through path is present in this tip; configure coolant delivery externally before running the program.
