Seco 75054601 Replaceable Tip Milling Shank Minimaster

Product Description

The SECO 75054601 is a replaceable tip milling shank in the Minimaster series, designed for use with MM08-style interchangeable milling heads. The shank accepts standard Minimaster tip inserts and provides a rigid, repeatable connection between the toolholder and the cutting tip. With a conical shank shape and 87-degree shank type, this tool is built for precise milling operations where quick tip changes and consistent tool runout are required. Overall length is 2.95 inches, effective cutting length is 1.06 inches, and the neck diameter measures 0.299 inches. Machinists and toolroom professionals install this shank in CNC milling centers and manual mills.

This shank is suited for light to moderate milling applications where modular tooling systems improve changeover speed. The Minimaster platform allows tip replacement without removing the entire assembly from the spindle, reducing downtime in production environments. The 5/8-inch shank diameter makes it compatible with standard collet chucks and toolholders used in vertical and horizontal milling setups. It is appropriate for shops running small-diameter profiling, slotting, or contouring operations where the MM08 tip system is already in use.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked state before changing tips or installing the shank. Use the appropriate torque wrench and tip-tightening tool specified by the Minimaster system — do not overtighten by hand. Inspect the shank seating surface and collet bore for chips or debris before securing the assembly.
