Milwaukee 2526-21XC 12V Cordless Oscillating Tool Kit; Universal Open Back Connection, Brushless Motor: Yes

These oscillating tools are powered by Milwaukee batteries of a compatible series and matching voltage. The batteries can also power other Milwaukee tools. Tools using lower-voltage batteries are generally lighter and more compact but less powerful than tools using higher-voltage batteries. Tools using lower-capacity (Ah) batteries are less bulky but store less power than tools using higher-capacity batteries.brbrMilwaukee oscillating tools have a universal mounting interface that provides a direct fit with blades that are oscillating interface system (OIS) compatible. It can also accept adapters for some non-OIS blades. Tools with a universal open back allow tool-free blade changes when used with Milwaukee OPEN-LOK blades.
