Seco 74034244 Keyway Milling Tip 0.307in 2 Flute Carbide

Product Description

The SECO 74034244 is a keyway-style replaceable milling tip designed for slotting operations in the Minimaster (MM08) series tooling system. Built from carbide substrate with a PVD-applied TiAlN coating and grade T60M, this tip delivers the wear resistance and edge retention required for demanding slot milling applications. It features a 0.307-inch cutting diameter, a maximum depth of cut of 0.213 inches, and a functional length of 0.268 inches. The right-hand cut geometry and 90-degree lead angle make it suited for full-width slotting passes. Licensed tooling professionals and CNC machinists are the primary installers.

This tip is used in keyway and slotting operations on machining centers and CNC milling platforms equipped with compatible MM08 Minimaster holders. It is appropriate for applications requiring precise, repeatable slot widths in materials matched to C5 material grade tooling. The D03 chipbreaker geometry assists with chip evacuation during slotting cuts. Coolant-through is not supported by this tip; external or flood coolant is the standard approach for heat management at this cutting diameter.

• T60M manufacturer grade rated for C5 material group workpieces
• Meets ANSI standards; tip conforms to MM08 Minimaster system interface

Compatibility

Designed as a replaceable milling tip for Minimaster MM08 series toolholders. Compatible insert size designation is 0.307T-R0.5. Verify holder compatibility with the MM08 system before ordering.

Installation Notes

Installation is performed by tooling technicians or machinists familiar with indexable milling systems. De-energize and lock out the machine spindle before seating or removing any replaceable tip. Use the manufacturer-specified torque wrench and drive key for the Minimaster clamping screw to ensure proper seating. Inspect the holder pocket for debris or wear before installing a new tip.
