Seco 74052646 Milling Tip 0.500 in 2 Flute Carbide Tialn

Product Description

The SECO 74052646 is a carbide end replaceable milling tip designed for use in the Minimaster MM12 modular milling system. This right-hand, 2-flute insert features a TiAlN coating applied via PVD process and a manufacturer grade of T60M. The tip measures 0.627 inches in functional length with a maximum depth of cut of 0.480 inches and a cutting width of 0.500 inches. A 90-degree lead angle and 0.250-inch corner radius define its profile geometry. It is installed by machinists and tooling technicians in CNC milling operations requiring a quick-change, replaceable-tip configuration.

This milling tip is suited for a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The M05 chipbreaker geometry is matched to these material groups and performs in both roughing and finishing passes depending on feed and speed parameters. It is commonly used in horizontal and vertical machining centers where the MM12 modular holder system is in service. No coolant-through capability is present in this tip, so external coolant application should be planned accordingly.

Compatibility

Designed for use with the Minimaster MM12 modular milling system. Insert size designation is 0.500-B90P. The full milling tip designation is MM12-0.500-B90P-M05. Confirm holder compatibility using the MM12 series designation before ordering.

Installation Notes

End replaceable milling tips are seated and torqued into compatible MM12 modular holders by a machinist or tooling technician following the holder manufacturer torque procedure. Ensure the machine spindle is fully stopped and locked out before tip exchange. Inspect the seating pocket for chips or debris before installing the tip, as contamination will affect runout and tip life. Follow shop tooling procedures and any applicable safety standards for rotating cutting tools.
