Parlec EROS20-10MM ER20 Collet 10mm

Product Description

The PARLEC EROS20-10MM is an ER20 series collet with a 10mm bore capacity, designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accept ER20 collet chucks. ER collets are the industry-standard workholding solution for gripping drill bits, end mills, reamers, and other round-shank cutting tools during precision machining operations. This collet holds a nominal bore diameter of 10mm and is engineered to deliver consistent clamping force and accurate tool runout when properly seated in a compatible ER20 chuck. Machinists and CNC operators install these collets as part of everyday tooling setups in production and job-shop environments.

ER20 collets are widely used in both light-duty and general-purpose CNC machining applications. The ER20 series accommodates a relatively compact collet chuck, making it a common choice for smaller vertical machining centers, drill-tap machines, and manual mills where spindle clearance or table space is a consideration. This 10mm collet is suited for gripping standard metric-shank tooling used in ferrous and non-ferrous metal cutting, as well as woodworking and composite machining applications.

Key Features

• ER20 collet series for use with ER20-compatible collet chucks
• 10mm nominal bore capacity for metric-shank tooling
• Industry-standard ER profile for broad chuck compatibility
• Compact form factor suited for smaller spindle assemblies
• Lightweight construction at 0.1 pounds

Compatibility

Designed as an OEM-style replacement or standard tooling collet for use with ER20 collet chucks and tool holders accepting the ER20 collet series.

Installation Notes

ER collets are installed and removed by machinists or CNC tooling technicians using an ER collet nut and the appropriate spanner wrench for the ER20 nut size. The spindle or collet chuck must be stationary and the machine powered down or in an e-stop state before changing collets. Ensure the collet is properly snapped into the collet nut before threading the assembly into the chuck body, and tighten to the chuck manufacturer's specified procedure. Inspect the collet bore and chuck taper for chips or debris before each installation to maintain runout accuracy.
