Product Description

The ACCUPRO 784952 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle applications that accept ER25 toolholders. This collet clamps cutting tools with a decimal inch size of 0.469 inches and a minimum collet capacity of 0.438 inches, giving machinists a reliable clamping range for that shank diameter. The compact profile measures 1.9 inches in height and 1.2 inches in diameter. Weighing 0.1 pounds, it is a lightweight, single-piece precision tool-holding component installed by machinists and CNC operators during tool setup.

This collet fits standard ER25 collet chucks and is suited for production and job-shop environments running milling, drilling, reaming, or tapping operations. The ER25 series is one of the most widely used collet standards in the industry, making this size a common replacement or supplemental collet for shops maintaining a full range of shank-size coverage. It is packaged and sold individually, making it practical for targeted tooling replenishment.

Installation Notes

Installation is performed by machinists or CNC setup personnel during tooling changeover. Before installing or removing collets, ensure the machine spindle is fully stopped and all energy is locked out per facility lockout/tagout procedures. Use the appropriate ER25 collet nut and spanner wrench to seat and torque the collet chuck assembly according to the toolholder manufacturer guidelines. Inspect the collet bore and seating taper for chips or debris before each use to maintain clamping accuracy.
