Parlec ER11-0157 ER11 Collet 0.1575 in Capacity

Product Description

The PARLEC ER11-0157 is an ER11 series collet designed for use in CNC machining centers, milling machines, and high-speed spindle applications. It accepts tooling with a maximum shank diameter of 0.1575 inches and has an overall length of 0.708 inches, making it suited for compact ER11 toolholders where precision and repeatability are critical. This collet is installed by machinists and toolroom technicians and provides consistent clamping force across its capacity range. The 4.00 mm nominal collet size aligns with standard ER11 collet nut systems used in production and job-shop environments.

The ER11-0157 is used in applications requiring precise tool runout control in smaller-diameter tooling setups. It fits ER11-compatible collet chucks found on CNC mills, routers, and precision grinding spindles in both production and maintenance machining environments. The collet is appropriate for light to moderate cutting loads where accurate tool projection and minimal vibration are priorities.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or removing collets, ensure the machine spindle is fully de-energized and at a complete stop. Use the appropriate ER11 collet nut and spanner wrench rated for the spindle speed of the application. Inspect the collet bore and chuck taper for chips or contamination before seating the collet to ensure accurate tool runout.
