Parlec ERS20-0500 ER20 Collet 0.5 Inch

Product Description

The PARLEC ERS20-0500 is an ER20 series collet designed for use in ER20-compatible collet chucks on CNC machining centers, milling machines, and drilling equipment. It accepts a 0.5 inch (1/2 inch) round shank tool and has an overall length of 1.24 inches with an overall diameter of 0.827 inches. The collet operates at a clamping pressure rating of 1800, ensuring consistent tool grip and concentricity during cutting operations. It is typically installed by machinists and CNC setup technicians as part of a precision toolholding assembly.

This collet is suited for light to medium-duty machining applications in job shops, production facilities, and maintenance environments. The ER20 series is a widely adopted standard in precision toolholding, and this collet fits within that system to hold drills, end mills, reamers, and other 0.5 inch shank tooling. It is a single-piece component installed directly into an ER20 collet chuck body.
