فكوك، قابلة للعكس لظرف 4 فكوك 4 بوصة

Put these on my 4-jaw chuck and the reversible design is a nice touch for getting extra wear out of them. They fit snugly and hold workpieces securely without any wobble. Exactly what I needed as a direct replacement.

The four jaws in this set are all identical, so I didn't have to worry about matching up a mixed batch when replacing the worn ones. They seat firmly in the chuck slots with no wobble, and the reversible feature makes gripping both internal and external work pieces straightforward.

The reversible design is perfect for getting double the use out of each jaw, and the fit was spot-on for my 4-jaw chuck. Installation took just a few minutes, and now my setup grips far more securely than with the old set.
