Seco 75054602 Replaceable Tip Milling Shank MM08

Product Description

The SECO 75054602 is a replaceable tip milling shank designed for use with the Minimaster MM08 toolholder system. It accepts interchangeable milling tips, allowing cutting heads to be swapped without removing the shank from the spindle. The shank features a conical shape with an 85-degree shank type, a 5/8 inch (0.6250 inch decimal) shank diameter, and an overall length of 4.72 inches. The neck diameter measures 0.299 inches, providing clearance during milling operations. This component is installed by machinists and tooling technicians in CNC milling environments where quick tip changes and consistent tool projection are required.

This milling shank is suited for light to medium milling operations where the Minimaster MM08 system is in use. It is typically used on vertical and horizontal CNC machining centers in both job shop and production settings. The 72 mm (approximately 2.83 inch effective length) projection supports reach into workpiece features while maintaining rigidity. The head length of 1.89 inches and maximum cutting diameter of 0.6250 inches (15.88 mm) define the envelope for compatible tip selection. No Weldon flat is present on this shank.

Compatibility

Designed for use with the SECO Minimaster MM08 replaceable tip milling system. Compatible tips and bodies must conform to the MM08 interface standard. Verify tip style and head diameter match before ordering.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated. Follow the machine tool manufacturer torque guidelines for drawbar or collet clamping — do not use values not specified in the machine or toolholder documentation. Inspect the shank seating surface and tip interface for chips or damage before each assembly. Proper tool projection setup should be confirmed with a presetter or on-machine measurement before cutting.
