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.

Complete Metric WW Collet Set

The Sherline metric WW collet set contains 77 collets sized from 0.3 mm to 8.0 mm by 0.1 mm increments plus a blank collet that can be made into any size collet by the user. It comes in a finely finished hardwood box with 96 holes, leaving room for other collets should you have extras or inch sizes to store.

Collet Accuracy

These collets have a maximum runout of .002″ or less. If the WW collet adapter is trued in as suggested in the instructions, it will run dead true. This will allow the collet runout to be at its best. Collet sizes above 3/16″ (4.5mm), considered pot chucks, are not bored through. They are only bored .260″ deep and depending on your setup and length of the part, you may experience greater runout further away from the front of the collet.

Sherline manufactures these collets to standard WW specifications; however, we have come across collets that are called WW and will not fit our drawbar and adapter. Be sure to check WW collets made by other manufacturers to be sure they fit our adapter before purchasing them. Sherline manufactures a slightly larger .315″ adapter and drawbar set that will accommodate some of these other brands.
