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.

Product Description

About the Riser 3/8″ Insert-Holder Tool Post

A riser tool post is used to bring the cutting tool back to lathe centerline height when using a riser block to raise the headstock to turn larger diameter parts. The riser 3/8″ insert tool post holds either a 3/8″ square shank insert tool holder or a 3/8″ round holder.

This tool post is the riser version of Sherline’s standard height P/N 7600 insert holder tool post. It is designed to fit the larger 3/8″ square and round holders commonly used for carbide or diamond-inserted tips. It holds Sherline’s own P/N 2256 (RH) and P/N 2257 (LH) 55° inserted tip tool holders. It is machined from solid aluminum and has a black anodized finish.

NOTE: Carbide inserts and inserted tip tools are available through Sherline. Call for a complete listing or see our worldwide website.
