ER25 Collet Nut

The Schmidt TE46125 is a replacement collet nut for ER25 tool holders. The collet nut draws the collet into the taper bore of the holder as it is torqued, providing the clamping force on the tool shank. Replace collet nuts that show thread wear, deformation, or difficulty torquing to specification. Always use the correct size nut for the installed holder series. Use with the matching series wrench for proper torque.
