@summetj In reality of course, drivers can use drill bits, they just can’t do so as effectively as drills.
About the only person this warning is likely to be helpful for is the DIY-afficianado who may not be immediately aware of the difference between an ‘impact driver’ and an ‘impact drill’ (more commonly called a hammer drill). This tool is designed to spin fasteners like screws and nuts. A hammer drill is designed for drilling into hard stuff like masonry and concrete.
If that distinction isn’t meaningful to you, and you both don’t already know what an impact driver is and are already considering purchasing one for less than $40 on Meh, I feel pretty confident in asserting that you’d be unlikely to notice the difference.
@Aspirant_Fool@summetj Anyone who buys an impact driver expecting to use it as a drill will discover the difference immediately if they try to drill a hole in aluminum. The bit will get snapped off in the hole. It’s rather much of a glaring disadvantage, actually.
Yes, it is easy to get “impact rated” twist drill bits with 1/4" hex shanks. And they work just fine when using an impact driver to drill holes in wood or most plastics. Just stay away from soft metals.
I got a similar unit from same mfr off Amazon before they were booted off there. I used it a couple of times over six months, then the battery wouldn’t charge. Reached out to mfr and they refunded my money.
