Replacement Collet Nut for ER11 Holders

This collet nut replaces a damaged or lost clamping nut on ER11 tool holders. It is manufactured for CNC machines and high-speed routing applications where the original nut has worn out. The part is sold individually as a direct repair component.

Hardened Metal Construction

Precision grinding and hardening give the nut consistent clamping force and resistance to deformation under load. The black metal finish provides basic corrosion protection during workshop use. No additional hardware or lubricants are included in the package.

14 mm Thread Diameter Determines Fit

The nut has a 14 mm thread diameter and a 9 mm hole diameter, so it only fits holders with matching ER11 specifications. Builders using other collet sizes or thread standards cannot use this part.

Questions about this item

Will the 14 mm thread diameter match my existing ER11 tool holder for future replacement?

The nut uses a 14 mm thread diameter and 9 mm hole diameter, matching standard ER11 collet chuck specifications for direct replacement.

What dimensional limit determines whether this 19 x 12 mm nut fits inside my machine's spindle clearance?

Overall size is approximately 19 mm diameter by 12 mm length, so the 19 mm outer diameter is the critical clearance dimension.

Does the metal construction and 12 g weight mean the nut runs hot or adds vibration during continuous high-speed CNC operation?

Precision ground and hardened metal construction is designed for high-speed use; the 12 g mass is minimal and does not generate heat or noticeable vibration.
