Description of Williams PL 1600C 2 External Snap Pliers
External snap ring. Made of high quality carbon steel with a black oxide finish to resist rust and other corrosion. Tips are heat treated for secure grip. Pliers are provided with cushion grip handles. 4 pairs of tips.
These are great for light, delicate work, but sometimes you need brute force and they can't. Since then I have bought special external pliers for heavy work. Interchangeable tips. Especially the 90 degree angle.
