Seco 74018865 Milling Tip 0.394 in 2 Flute T60M Carbide

Product Description

The SECO 74018865 is an end replaceable milling tip designed for the Minimaster (MM10) modular milling system. It features a 0.394 inch cutting diameter, 2 flutes, and a right-hand cut geometry with a 90-degree lead angle. The tip is manufactured from carbide grade C5 with a TiAlN coating applied via PVD process, delivering hardness and heat resistance suited for aggressive metal-removal operations. Maximum depth of cut reaches 0.272 inches (6.9 mm), and the functional length is 0.335 inches (8.50 mm). Licensed HVAC and machine tool technicians performing slotting or shoulder milling operations on close-tolerance components will recognize this as a direct drop-in tip for compatible MM10 holders.

This milling tip is intended for slotting applications across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The M03 chipbreaker geometry supports chip evacuation during full-width slotting passes. It is sized for use in MM10-series modular milling holders and carries ANSI standards compliance. Minimum order quantity is 2 pieces; each package contains 1 tip.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before removing or seating the milling tip. Seat the tip fully into the MM10 holder and torque the retention screw per the holder manufacturer specifications using the appropriate Torx or hex key. Inspect the seating surface and threads for contamination or damage before each tip change to maintain runout tolerance.
