Built to accept 3\/4 inch square stock, it features a 1-11\/16-20 internal thread and an M47.5 x 1.75 external thread for secure, repeatable seating in compatible collet chucks and holders. With an overall length of 4.31 inches and a total indicator runout (TIR) of 0.0011 inches, this collet delivers the tight tolerances required in production machining environments. It is installed by machinists and toolroom technicians working on milling, turning, or secondary machining operations where square-profile workholding is required.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in machine shops running CNC mills, lathes, or machining centers where square-bar stock, square-shank tools, or square-profile workpieces must be held concentrically and securely. The square bore geometry makes it the correct choice when round collets are not appropriate for the workpiece profile. Typical applications include production runs and precision setups in both job-shop and high-volume manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch square bore accommodates square-profile stock and tooling\u003c\/li\u003e\n  \u003cli\u003e0.0011 inch TIR for precision runout control in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003e1-11\/16-20 internal thread for secure chuck engagement\u003c\/li\u003e\n  \u003cli\u003eM47.5 x 1.75 external thread for proper seating in compatible holders\u003c\/li\u003e\n  \u003cli\u003e4.31 inch overall length provides adequate reach and clamping depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style square collet replacement or new installation for compatible collet chucks and toolholding systems that accept M47.5 x 1.75 external thread collets with a 1-11\/16-20 internal thread interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before inserting or removing collets. Ensure mating chuck threads are clean and free of chips or debris before threading the collet into the holder.
