How universal are drills and bit sets? Can I mix and match bit brands with drill brands? For example, would a Black and Decker bit set work with a Kobalt drill? Sorry if it's a stupid question, I'm quite new to all of this. Thanks!
They're universal. That'll work just fine. Drills have chucks with three jaws that clamp down on whatever you stick in them, so they can use round-shank bits and hex bits too.
