Review on Cleveland Speed Length Degree Notched by Jeff Jordan

I was expecting the 5/8" bit to have a 1/2" shank so it would have no problems fits into a standard 1/2" drill chuck. I've looked for shank sizing information but can't find it on Revain's website or the manufacturer's website. Luckily my drill chuck opened wide enough to use the drill. I suggest not ordering drills until you know the shank size.
