ER11 A collet nut for milling chucks

This ER11 A international standard nut fits ER series tool holders and compatible collet chucks used in CNC milling. It secures the collet to hold cutting tools during machining operations. The component is supplied new as a single piece for workshop use.

Replaces worn or missing ER11 nuts on existing

Upgrade when the original nut is damaged, stripped or lost and the chuck body remains serviceable. The jump is worth it if the thread profile matches your current ER11 A specification and no larger collet capacity is required. Buyers needing a different ER size or a complete chuck assembly should look elsewhere.

Questions about this item

What ER collet size does the ER11 A nut accept?

The ER11 A nut is designed for ER11 collets, which have an 11 mm clamping range.

How do I install the ER11 A nut onto the tool holder, and what is the common mistake?

Thread the nut onto the ER series tool holder by hand, then tighten with an ER11 spanner; the common mistake is over-tightening without a collet seated, which can damage the threads.
