Parlec ERS40-0236 ER40 Collet 6 Mm

Product Description

The PARLEC ERS40-0236 is an ER40 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts ER40 toolholders. This collet grips 6 mm shank tooling - including drills, end mills, and reamers - with a clamping pressure rating of 1,800 psi for secure, repeatable tool holding. The overall length is 1.811 inches and the overall diameter is 1.614 inches. Machinists and toolroom technicians rely on ER-style collets for their wide clamping range, ease of tool changes, and broad compatibility with standard ER40 chucks across multiple machine platforms.

This collet is suited for light to heavy cutting operations in both production and job-shop environments. It fits any standard ER40 chuck or collet holder, making it a practical choice for shops running a variety of CNC or manual spindle equipment. The 6 mm bore size accommodates common metric shank tooling used in general machining, die-and-mold work, and precision drilling applications.

Installation Notes

ER collets are installed and removed by a qualified machinist or toolroom technician using the appropriate ER40 collet nut and spanner wrench. Always ensure the spindle is fully stopped and the machine is powered down before changing collets. Inspect the collet bore and chuck taper for debris or damage before seating. Do not exceed the rated clamping pressure or use a collet with a bore size that does not match the tool shank diameter.
