I like the procuner holders.
it uses a nut and collet so you wont drop collets. the #1 goes up to 1/4 " and is 3/4 shank and only about 3 inches long.
the problem is that i still break taps on my fadal. I would have to say that it is the #1 source of scrap parts in my shop. I have started to tap all blind holes on a drill press with a tapmatic head and haven't broken a tap with it yet
