website does not have size specs for bit i purchased, i wrote emails asking for information on sizing etc as well as called multiple times only to get a recording that there is a high call volume to call back later which i did many days in a row with no reply or answer, finally i went ahead and purchased due to the fact we need it asap but of course once it arrived (late) after multiple delays just as i hoped would not happen it does not fit my machine, if specs had been onsite or i recieved a reply email this wouldve saved alot of hassle as well as wasted time and retrurn costs.
