Accupro ER20HP 10.32 ER20 Collet 13/32 Inch

Product Description

The ACCUPRO ER20HP 10.32 is an ER20 series precision collet sized at 13/32 inches, designed for use in CNC machining centers, milling machines, and router spindles that accept ER20 toolholding systems. This collet provides a total indicated runout (TIR) of 0.0002 inches (0.0050 mm), making it well suited for applications where concentricity and repeatability are critical. With an overall length of 31.5 mm and a weight of 0.35 pounds, it is a compact, direct-fit component installed by machinists and toolroom technicians during setup or tooling changes.

This collet is appropriate for light to medium-duty cutting operations in both production and job-shop environments. It accommodates round shanks at the 13/32 inch nominal bore and is used in horizontal and vertical machining centers, CNC mills, and dedicated ER20 collet chucks. It is a single-piece unit sold individually and is suited for shops requiring precise toolholding at this bore size.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The spindle or collet chuck must be fully stopped and de-energized before inserting or removing collets. Seat the collet into the ER20 chuck before threading the collet nut to avoid damage to the collet taper. Torque the collet nut using the appropriate ER20 spanner wrench; refer to the machine tool manufacturer specifications for proper clamping force.
