Lathe chuck wrenches help prevent one of the most common accidents on lathes: when a chuck wrench (or key) is thrown from the chuck. This happens when someone forgets to remove the chuck wrench from the chuck before the machine is turned on.
A self-ejecting, spring-loaded chuck wrench can be used on lathes or other machines equipped with manually adjusted chucks. The spring-loaded sleeve ejects the wrench from the chuck after each use. These wrenches are engineered and designed to provide proper loads for self-removal of the wrench weight.
The standard lathe chuck wrench has a stationary 5 1/2-inch or 9 1/2-inch handle and 8-inch long body. The longer-handle lathe chuck wrench has a sliding, 18-inch handle and 10-inch long body.
Chuck wrenches are available in both inches and millimeters, as well as hexagon and square shaped. Click on the tabs to view more details for each type of chuck wrench.
