good question, i never really thought off welding them on. 1/4 stub for a pilot and a 1/2 stub for the holes and i was through in just a minute or so. i have a milwaukee magnum 1/2 inch drill.
Mike you cant get parts for the hole shooter anymore ??? That sucks, I have two of those one with the metal keyless that I know I can not get anymore.....
My Milwaukee Magnum must be 30 years old and stll strong. /forums/images/graemlins/grin.gif It sure makes me sad to see Milwaukee put all effort into cordless tools that last much less /forums/images/graemlins/mad.gif and have $70 batteries instead of really durable tools.
They sure did wrong when they changed from the old style circular saw to the new "tilt lock" model. Piece of junk compared to the old.
I need to buy some of the old stuff off ebay /forums/images/graemlins/smile.gif while it still exists.
