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.

Replacement Carbide Insert for 7620 Fly Cutter

Product Description

About the Replacement Carbide Insert

This is the replacement carbide insert for the Single Flute Insert Fly Cutter. Though not inexpensive, when you consider you are getting two cutting tools in one and are saving a lot of time in tool sharpening, it is really a pretty good deal.

Carbide cutters give good finishes on hard-to-machine materials such as cold rolled steel. They will also work on aluminum, brass or leaded steels, and will last practically forever; however, the best finishes on those materials are still achieved with a good, sharp high-speed steel tool.

NOTE: Replacement carbide inserts for other inserted tip tools are available through Sherline. See our page on carbide tools.
