Leave it to Powerbuilt to design better, smarter snap-ring pliers. For starters, they convert from internal to external with the flip of a switch - no more handle changes. Next, when it comes time to swap out tips, simple open the tip lock levers to remove and install tips. No tiny hex key wrench or fumbling with microscopic set screws. Last but not least, Powerbuilt fit, comfort and quality make these handy pliers a pleasure to use, day in and day out.
