A set of tough and extra-long lasting titanium nitride (TiN) coated TurnMaster Excelsior Cutters for Sorby's versatile TurnMaster Tool. Includes one each of their primary cutters - the #1 Round, #2 Detail Point, and #3 Square. The titanium nitride coated Excelsior tips cut crisp detail and leave a fine finish. They offer the same characteristics as plain HSS, but with the added toughness (Rc of 90) and prolonged edge life that TiN provides. Works with any of Sorby's handled or un-handled TurnMaster shanks. Cutters are re-sharpenable. England
