Seco 75015060 Minimaster MM16 Milling Shank 1 Inch

Product Description

The SECO 75015060 is a replaceable tip milling shank in the Minimaster series, designed to accept MM16-style milling tips for modular end mill assemblies. The shank features a 1-inch (25.40 mm) conical 85-degree shank diameter, a 0.598-inch neck diameter, and an overall length of 6.69 inches. With a projection of 114 mm and an effective length of 4.49 inches, this toolholder provides the reach needed for pocketing, slotting, and profiling operations where a standard-length tool would not clear the workpiece. It is installed by machinists and tool setup technicians in CNC milling environments.

This shank is suited for milling applications in both production machining and job-shop environments. The MM16 Minimaster toolholder style supports quick tip changes without removing the shank from the spindle, reducing changeover time during multi-operation runs. The 85-degree conical shank geometry is matched to compatible spindle interfaces and tooling systems that accept this configuration. No Weldon flat is present on this shank.

Installation Notes

Installation and tool setup should be performed by qualified machinists or tool crib personnel familiar with modular milling systems. Ensure the spindle and toolholder interface are clean and free of chips before seating the shank. Torque the replaceable tip according to the tip manufacturer's documented procedure using the correct torque wrench — do not estimate by feel. Verify runout with a dial indicator before cutting.
