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.

Expanding Ring Mandrel
Sherline Products, in collaboration with Bryan D. Drummond (gem cutter and goldsmith), designed this Expanding Ring Mandrel specifically for making and modifying rings on the Sherline lathe.
The mandrel is manufactured from 12L14 steel and features a black oxide finish for rust prevention.
It is designed for use with stepped ring collets manufactured by Ring Tech (Faceting Collets Stepped). These Ring Tech collets are known for their excellent quality and superior design, and, like our machines, are made in the USA. If you buy collets from Ringtech, tell them Sherline sent you.
If you are using a brand of collet that is shorter than the Ring Tech collets, the mandrel includes a spacer washer that fits against the shoulder of the mandrel. This allows shorter collets to be properly positioned at the front of the mandrel.

Jeweler Burr Holder
These specialized holders were developed at the request of a jewelry design customer. Similar to our standard end mill holders, they feature a longer body with a tapered end, allowing better visibility of the cutter and improved access for working in cavities.
Each holder includes two Tommy bars and one 1/16" hex key.
Jeweler DOP Holder
Sherline Products, in collaboration with Bryan D. Drummond (Gem Cutter & Goldsmith), has designed this DOP Holder specifically for securely holding lapidary DOP sticks during gemstone cutting. If you already own one of our machines, the holder is designed to thread directly onto our ¾-16 headstock spindle nose. It will also be an essential accessory for our upcoming gem cutting machines.
Compatible with Ultra Tec® Dops This DOP Holder has been precisely engineered with tolerances and a keyed dop system designed for compatibility with Ultra Tec® brand dops which are used on their faceting machines. Many gem cutters use Ultra Tec equipment for flat faceting, and the keyed dop feature provides secure alignment and ease of use, making it a valuable addition to your setup. Sherline does not manufacture dops, but they can be purchased directly from Ultra Tec. Like Sherline, Ultra Tec products are high-quality and Made in the USA. Shop Ultra Tec Dops Features:

Sherline Precision Jewelers Lathe
The 8″ tabletop lathe is an ideal precision tool for jewelers and gem cutters working on small, detailed components such as rings, settings, mandrels, bezels, bushings, and custom fixtures. It can turn parts up to 3.5″ in diameter over the bed or 1.88″ over the carriage, with 8″ of distance between centers, providing ample capacity for most jewelry and lapidary work without unnecessary machine size.
For jewelry applications, we often recommend the 8″ tabletop lathe over our 17″ model. The additional bed length of the 17″ lathe is rarely needed for typical jeweler or gem-cutting tasks, and its longer layout requires reaching farther to operate the Z-axis handwheel. The compact design of the 8″ lathe keeps both handwheels close to the work area, allowing for greater control, improved ergonomics, and more precise hand-fed cuts during fine finishing operations.
The lathe features an electronic speed control that provides continuously variable spindle speeds from 70 to 2,800 RPM without belt changes, making it easy to dial in the correct speed for delicate materials and small-diameter tools. A secondary pulley position is available when additional low-RPM torque is needed for tougher materials or heavier cuts. Despite its compact footprint, the machine is rigid and stable, delivering the smooth, controlled operation required for jewelry-scale precision.
