Self-Ejecting Lathe Chuck Wrenches
$394.16 – $504.34
Product Description
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.
