Parlec EROS20NW Torque Collet Chuck Wrench Eros20

Product Description

The PARLEC EROS20NW is a torque-style collet chuck wrench designed for use with the ERos20 collet series. It provides controlled, repeatable clamping force when seating or releasing collets in compatible chuck bodies. Proper torque application during collet installation reduces runout and helps maintain tool holding accuracy over time. Machinists and toolroom technicians rely on dedicated torque wrenches like this one to avoid over-tightening, which can damage collet tapers or chuck threads. The EROS20NW is a purpose-built accessory for shops running ERos20 toolholding systems on CNC machining centers or manual milling machines.

This wrench is intended for use in machine shop environments where ERos20 collet chucks are part of the toolholding setup. It is suited for production machining, toolroom work, and job shop applications where consistent collet seating is required. The torque wrench format supports repeatable setup procedures, which is particularly important in high-volume or precision machining operations where tool runout tolerances are tight.

Compatibility

Designed for use with PARLEC ERos20 series collet chucks. Specific compatible chuck model numbers were not provided in the available product data; consult PARLEC documentation to confirm fitment with your ERos20 chuck body.

Installation Notes

Installation and collet changes should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Clean the collet taper and chuck bore before seating the collet to prevent contamination-related runout. Apply torque gradually and evenly; do not use impact tools or extension bars on this wrench. Follow the chuck manufacturer's recommended torque procedure for the ERos20 series.
