The patented pliers are equipped with interchangeable tips (straight, 15°, and 90°) that can be quickly adapted for internal or external retaining rings depending on the application. Five pairs of tips are included with the 160 mm and 200 mm pliers, and six pairs with the 250 mm pliers. Suitable for internal retaining rings with a diameter of 8 to 100 mm and external retaining rings between 3 and 100 mm in diameter. The pliers cover the range of ten conventional pliers.
