These Pen Blank Jaws for the Viper2 Chuck are purpose‑designed for gripping both wood and acrylic pen blanks with absolute accuracy. A precision‑machined internal V‑cut forms a perfect square when the jaws close, giving you a secure, non‑slip hold on standard pen blank sizes without crushing or distorting the material.
The external dovetail profile adds versatility, allowing the jaws to be used for small recesses when needed—making them a valuable addition to any pen turner’s setup.
