Important Update Regarding Sherline Products
October 20, 2026
We would like to share an encouraging development regarding the future of Sherline Products.
We are currently in discussions with an American manufacturer regarding the potential purchase of Sherline’s intellectual property and remaining inventory. The goal of this proposed acquisition is to preserve and revitalize the Sherline brand while providing continued availability of replacement parts, accessories, and machines for our valued customers.
As these discussions progress, we have agreed to temporarily suspend accepting new orders, effective October 19, 2026. This will allow us to preserve our remaining inventory while negotiations are underway.
Although no final agreement has been reached, we are hopeful that this opportunity will provide a positive path forward for the Sherline name and the customers who have trusted our products for more than five decades.
We sincerely appreciate your patience, understanding, and continued loyalty during this transition. We will share additional information as soon as it becomes available.
Our greatest hope is that the Sherline legacy of quality, precision, and American craftsmanship will continue for generations to come.

3/8″ Dia. Straight Shaft Chuck Arbor

(Chuck not included, shown for reference only)

SKU: 11850 Categories: ,

About the Straight Shaft Arbor

We designed this chuck arbor to mount our 1/4″ and 3/8″ drill chucks in our multi-tool holders with 3/8″ mounting holes*. This straight shaft arbor will also work with our 3/8″ insert holder tool post (P/N 7600). It will work with any chuck that has a 3/8 x 24 thread. It has a 3/8″ diameter straight shaft with a machined flat for holding in the posts. Ensure the flat surface on the arbor is oriented toward the top of the tool post, so the 10-32 x 3/4″ SHC screw will be perpendicular to the flat. This orientation will assure that the arbor does not turn or move when force is exerted on the tool.

Just remove the existing arbor from the chuck and replace it with P/N 11850 arbor.
