Accupro 587468 ER50 Collet 1.259 Inch 32mm

Product Description

The ACCUPRO 587468 is an ER50 series precision collet designed for use in CNC machining centers, milling machines, lathes, and other rotating spindle equipment. It accepts a maximum collet capacity of 1.259 inches (32.00 mm) with a minimum collet capacity of 1.181 inches (30.0 mm), giving the operator a usable clamping range suited to larger-diameter tooling. The 587468 holds a total indicated runout (TIR) of 0.01 mm, supporting accurate, repeatable tool positioning. Machinists, toolroom technicians, and CNC setup personnel install this collet as part of an ER50 toolholding system.

The ACCUPRO 587468 fits ER50 collet chucks commonly found in heavy-duty machining applications where larger shank diameters are required. Typical use cases include face milling, boring, and end-mill operations on industrial CNC machining centers and manual mills equipped with ER50-compatible spindle toolholding. It is packaged individually and is well suited for production shops and toolrooms needing precise, consistent tool clamping at larger diameters.

Installation Notes

Installation of ER50 collets is typically performed by a machinist or toolroom technician. Before changing collets, ensure the machine spindle is fully stopped, locked out, and de-energized per your facility lockout/tagout procedures. Seat the collet fully into the ER50 nut before threading onto the chuck body, and tighten using a proper ER collet wrench to manufacturer torque specifications for the chuck. Inspect the collet bore and seating surfaces for chips or damage before each use to maintain runout performance.
