just received this yesterday and am happy as long as it fits very well no play as long as I have an 8" eskimo drill bit its a solid build and i like the round plastic fall protection, it's strong and durable too, i haven't used it yet but i'm pretty sure it will be fun to drill holes now, i hook it up to my milwaukee m18 fuel -Impact drill on, I'll update my review after this beast is tested, ok enjoy guys!
