Seco 75015053 Minimaster Milling Shank 3/4 Inch MM10

Product Description

The SECO 75015053 is a replaceable tip milling shank from the Minimaster series, designed for use with MM10-style milling tip inserts in CNC machining operations. The shank features a 3/4 inch (0.7500 inch) conical shank diameter with an 87-degree shank type, allowing secure seating in compatible toolholders. The neck diameter measures 0.3750 inches, enabling access to tighter workpiece geometries without interference. Overall length is 3.3000 inches, with an effective cutting length of 2.4400 inches and a head length of 0.9060 inches. This shank is intended for professional machinists and tooling specialists performing milling operations on CNC machining centers.

This replaceable tip milling shank is suited for milling applications in manufacturing and job shop environments where the Minimaster MM10 system is in use. The replaceable tip design reduces tooling costs by allowing tip replacement without discarding the shank body. Typical applications include profiling, slotting, and general milling operations requiring a compact, high-rigidity toolholding interface. The conical shank shape contributes to accurate and repeatable tip positioning during setup and changeover.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with replaceable tip milling systems. Power down and lock out the machine spindle before mounting or removing the shank or tip insert. Use the correct torque wrench and tip key specified for MM10 components — do not improvise with non-rated tools. Inspect the shank seat and tip interface for chips or contamination before each assembly to ensure accurate runout.
