Seco 74034546 Chamfer Milling Tip 0.315in T60M Carbide MM08

Product Description

The SECO 74034546 is a chamfer-style replaceable milling tip designed for use in the Minimaster MM08 modular end mill system. Built from solid carbide grade C5 with a PVD-applied TiAlN coating, this tip delivers hardness and thermal resistance in demanding interrupted and continuous cutting conditions. It features a 60-degree lead angle, producing a 30-degree chamfer on the workpiece, and runs two flutes with an E03 chipbreaker geometry. Maximum depth of cut is 0.13 inches, and cutting diameter is 0.165 inches. Right-hand cutting orientation. Licensed machinists and CNC setup technicians install this tip as a quick-change insert on compatible MM08 shanks.

The 74034546 is suited for chamfering and light milling operations across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its compact functional length of 0.302 inches makes it appropriate for short-reach applications where rigidity and precision entry geometry are priorities. It is sold individually per package with a minimum order quantity of 2 units.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before seating or removing the milling tip. Use the appropriate torque wrench and SECO-specified clamping screw to secure the tip to the shank — do not overtighten by hand or use non-specified tooling. Confirm correct seating and runout with a dial indicator before returning the tool to service.
