Case Trimmer Collet

Brown & Sharpe-style Collets is one of the secrets to precise and repeatable case trimming.

If the case isn’t properly inserted and securely held in the case trimmer, any subsequent operation will not be accurate.

The internal Collet steps ensure that the case head is firmly seated in the Collet, even when there is case rim diameter variation, unlike one-size-fits-all universal chuck heads or multi-piece shell holders.

The tapered design ensures that the Collet securely closes on the case rim without pulling the case back. When you lock a case into one of our Case Trimmers, it stays exactly where you put it.

All Henderson trimmers are supplied with Collet #1 included as standard.
