Accupro 588886 ER25 Collet 0.747 Inch

Product Description

The ACCUPRO 588886 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment. It accepts a maximum tool shank diameter of 0.747 inches and a minimum collet capacity of 0.719 inches, providing a 0.028-inch clamping range within the ER25 standard. The collet applies up to 1000 units of clamping pressure to secure cutting tools, drill bits, and end mills during operation. Machinists and CNC operators install this collet into a compatible ER25 collet chuck or tool holder. The part ships individually and is sold as a single-piece unit.

The ACCUPRO 588886 is suited for precision machining applications in both production shop and job shop environments. ER25 collets are among the most widely used toolholding components in CNC milling and turning setups. This collet is appropriate for securing tool shanks at or near the 0.747-inch nominal size in any spindle or holder built to the ER25 standard. It is a common replacement or supplemental collet for shops running mixed tool diameters across a standard ER25 chuck set.

Compatibility

Designed as an OEM-style replacement or supplemental collet for use with ER25-standard collet chucks and tool holders in CNC milling, drilling, and turning applications.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before installing or removing the collet, ensure the machine spindle is fully stopped and the machine is locked out per shop safety procedures. Seat the collet into the ER25 chuck body before inserting the tool shank, then tighten the retention nut to the chuck manufacturer's specified torque using an ER collet wrench. Inspect the collet for wear or out-of-round seating surfaces before each use to maintain runout tolerances.
