I have a Black & Decker corded drill/driver that is part of their Matrix platform that allows you to swap the head for different tools (see pic). It is also compatible with the Craftsman Bolt-On line which is why I owned this. I used this drill maybe twice since it was really just a backup corded tool in case my batteries were dead on my cordless tools. Switching to the Milwaukee M12 platform is the reason for selling off tools. See my other listings for more tools.
