Accupro 588892 ER25 Collet 0.56 Inch

Product Description

The ACCUPRO 588892 is an ER25 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts the ER25 collet system. It holds cutting tools with a decimal inch capacity of 0.56 inches, with a minimum collet capacity of 0.546 inches, giving the operator a reliable clamping range for end mills, drills, and similar tooling. At 0.7 pounds, this is a compact, precision-ground component intended for machinists and tooling technicians working in production or job-shop environments where accurate tool holding is critical to finished part quality.

The ACCUPRO 588892 is suited for use in any spindle or collet chuck that accepts the ER25 standard collet format. This includes vertical and horizontal machining centers, drill-tap centers, and manual mills equipped with ER25-compatible tool holders. It is sold individually and is appropriate for shops looking to expand their collet inventory or replace a worn collet in an existing ER25 setup.

Installation Notes

Installation and removal of ER25 collets should be performed by a qualified machinist or toolroom technician using the appropriate ER collet nut and spanner wrench rated for the ER25 system. Power down and lock out the machine spindle completely before inserting or removing any collet. Inspect the collet bore and seating taper for wear, chips, or debris before each use, as contamination directly affects runout and tool holding force. Do not exceed the tool shank diameter range stamped on or associated with this collet.
