Axminster, Expanding Pin Jaws

Product Description

The SK100 4" Expanding Pin Chuck Jaws offer a secure method of mounting logs, burls and other odd shaped pieces of timber, which defy other workholding options. They are an improvement on the traditional pin chuck. They only require a 30mm (1 3/16") diameter by 50mm (2") deep hole. It is important to use the full depth of the jaw. This gives the best possible grip, avoids stressing jaws and allows the jaw plates to give some support. These jaws will also grip small round or square section materials such as pen or lace bobbin blanks. They are suitable for the SK100 4" and SK114 4 1/2" chucks. Made from stainless steel to protect against corrosion.
