Seco 74052645 Ball Nose Milling Tip 0.375 in Carbide MM10

Product Description

The SECO 74052645 is a ball nose replaceable milling tip designed for use in the MM10 Minimaster modular end mill system. Manufactured from solid carbide with a PVD-applied TiAlN coating, this tip delivers wear resistance and thermal stability across a wide range of workpiece materials. It features a 0.375 inch cutting width, a 0.343 inch maximum depth of cut, and a 0.462 inch functional length. The two-flute, right-hand geometry paired with the M04 chipbreaker promotes efficient chip evacuation in profiling and contouring operations. This tip is installed and replaced by machinists and CNC operators in production and job-shop environments.

This milling tip is suited for profiling applications in both conventional and CNC milling machines using the MM10 Minimaster tool system. It is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, N, S, and H. The T60M grade designation indicates the carbide substrate and coating combination selected for these demanding material categories. Typical applications include die and mold work, contour milling, and finish profiling passes where a consistent ball nose geometry is required.

Key Features

• Carbide substrate with PVD TiAlN coating for extended tool life across multiple material groups
• 0.375 inch cutting width with 0.188 inch corner radius for true ball nose profile
• 0.343 inch maximum depth of cut supports aggressive profiling passes
• Two-flute right-hand configuration with M04 chipbreaker for controlled chip formation
• 90-degree lead angle and 0.462 inch functional length suit shallow-to-mid-depth contouring
• Replaceable tip design reduces tooling cost by allowing tip swap without discarding the holder

Compatibility

Designed for use with the MM10 Minimaster modular milling system. Insert size designation is 0.375-B90P. Compatible with MM10 series holders accepting the B90P interface.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or CNC technician with the machine spindle fully stopped and the machine in a locked-out, de-energized state. Use the appropriate Minimaster torque wrench or assembly tool as specified by the holder manufacturer to seat the tip correctly. Do not exceed recommended cutting parameters for the selected material group. Inspect the tip seating interface on the holder for wear or contamination before each tip change.
