Seco 75005069 Replaceable Tip Milling Shank MM10 Minimaster

Product Description

The SECO 75005069 is a replaceable tip milling shank designed for use with the Minimaster MM10 toolholder system. It features a 5/8 inch straight shank with a Weldon flat and keyway configuration for secure, repeatable tool positioning in milling operations. The overall length measures 2.56 inches, with a neck diameter of 0.508 inches and a head length of 0.669 inches. This shank accepts MM10-style replaceable milling tips, allowing fast tip changes without removing the holder from the spindle. It is suited for CNC machining centers and manual mills where quick tip indexing and consistent projection are required.

This shank is intended for milling applications in job shop, production machining, and tool room environments. The Minimaster system is widely used for profiling, slotting, and general milling tasks on ferrous and non-ferrous materials. The 5/8 inch shank diameter fits standard collet chucks and milling machine spindles that accept that bore size. The Weldon flat provides positive drive and prevents pullout under cutting loads, making it a reliable choice for both light finishing passes and moderate material removal operations.
