Accupro 588348 ER25 Collet 11 Mm

Product Description

The ACCUPRO 588348 is an ER25 series collet sized for 11 mm tooling, designed for use in ER25-compatible collet chucks on milling machines, machining centers, and CNC lathes. Collets of this type secure cutting tools, drills, and end mills by compressing radially when drawn into a matching chuck body. The ER25 collet standard is one of the most widely used toolholding formats in precision machining. At 0.7 pounds, this is a single-piece unit sold individually. It is installed and serviced by machinists, CNC operators, and toolroom technicians working in production or job-shop environments.

This collet is suited for light-to-medium duty machining operations where a reliable 11 mm tool bore is required. It fits any ER25-standard collet chuck body regardless of spindle taper type, making it a common replacement or additional unit for shops running multiple setups. Typical applications include vertical and horizontal milling, drilling, reaming, and tapping operations on CNC and manual machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Before changing collets, power down the spindle and confirm the machine is in a safe, locked-out state per your facility lockout/tagout procedures. Seat the collet fully into the nut before engaging the chuck body, and use a calibrated torque wrench with the appropriate ER25 spanner nut wrench to reach the manufacturer-recommended clamping torque listed in the chuck documentation. Inspect the collet bore and seating taper for chips or damage before each installation.
