Product details
NT ER collet holders pair the catalog's NT30, NT40 or NT50 machine connection with an ER tool-clamping system. They are intended for selection against the actual milling spindle and drawbar arrangement. Choose the ER family and needed collet bores separately, and check the holder's external diameter and L1 against the setup.
ER family coverage
The table lists ER16 through ER40 across the series, with fewer NT50 combinations.
Accessory coordination
Include the required ER collets and nut in the quotation scope if needed.

Models and specificationsCan an NT40 holder be selected just because the machine uses BT40?
No. Confirm the machine's complete interface and retention details; similar nominal sizes do not establish interchangeability.
Which ER sizes are listed for NT50?
The supplied table lists NT50-ER32 and NT50-ER40. Other combinations require separate confirmation.
Is the drawbar thread defined in this table?
No. Provide the machine's drawbar requirement for confirmation before order.
Does a listed family range mean the holder clamps tools without collets?
No. A correctly sized ER collet is required for each selected tool shank.
