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 3/8″ Rear Side Cutoff Multi-Tool Holder

The rear side cutoff, multi-tool holder, was designed to complement our four-position, gang-tooling tool posts. It can be used in conjunction with the gang-tooling tool post or on its own for our customers who want to convert their Sherline lathe into a “Chucker Lathe” or gang-tooling lathe.

This tool holder is designed to be used on the backside of the part with the cutoff blade mounted with the cutting edge facing down. The cutoff blade cannot be used on the front side of the part.

Our rear-side cutoff multi-tool holder offers a convenient and accurate way to hold up to two round boring tools with a known center-line-to-center-line distance of 1.500″, and a slot for holding a cutoff tool blade.

We also offer a tool holder for customers who want to use ER16 collet holders with a 5/8″ shank.

Using the Part-Off Tool

This holder can be mounted as shown in Figure 1, so the blade is in front of the crosslide. This will allow you to cut off larger diameter parts as long as the section to be parted off does not exceed 1.0” in length (the distance between the back of the part-off blade and the front of the crosslide).

FIGURE 1—The distance from the back of the part-off blade to the front of the crosslide is 1.0″ when the tool holder is perpendicular to the crosslide. Click on the image for a larger view.
