CAT-V Flange ER32 Strong & Rugged Collet Holder for 50 degree tapers (6" length)

End Mill Holders offered in stub, standard, extended and S&R (strong & rugged) models will meet your end milling needs. The fine pitch set screws match Weldon flats to firmly lock the end mill. All holders, except the stub holders, from 1/8" up to 1" diameter, can accept single- or double-end tools; the stub holder will only accept single-end tools. Holders (except the stub) for end mills 1" and larger have two locking screws. For your convenience, the locking screws are aligned with the drive slot. End mills without Weldon flats should not be used in these holders. S&R (Strong & Rugged) tool holders steady the tool for smoother and faster cutting. Tools last longer due to the added mass of the holder, which decreases vibrations. The tool holders accept double-ended end mills. Retention knobs must be ordered separately for each holder.
