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.

Knurling Tool Holder

Sherline’s knurling tool adds a professional touch to your parts by embossing knurls into the surface, rather than cutting them. Straight knurls are commonly used on the ends of shafts that will be pressed into other parts, while both straight and diamond knurl patterns are ideal for enhancing grip on handwheels and thumbscrews.

This tool can accommodate diameters up to 1″ (25 mm) and features both right and left sides that evenly clamp down on your part as it’s turned in the lathe, creating a consistent knurled pattern. It comes with one set of spiral knurls that form a diamond pattern.

Additional sizes of knurls for both diamond and straight patterns are also available in the addition knurls tab below.

Note: This knurling tool is not intended for use with riser blocks.
