    Mag drill help

    I recently jumped the gun and bought apparently the oldest living hougen mag drill. It is set up for 1/2 inch annular cutters like a end mill with 1 flat on it the motor is a milwaukee with a 5/8-16 thread. I called hougen and they said I'm sol. I just want to be able to use standard annular cutters. Any older guys have any experience or insight on the situation I don't know how to post a picName:  20210519_085130.jpg

    Maybejust maybe you can take the chuck out and replace it with a standard chuck? Just a thought. The chuck looks just like the one on my old Milwaukee, not sure about the sizes though.

    What is considered the chuck? Is there an ejector spring in the quill?

    I have the same mag drill which is an old Hougen Rota Broach. Unfortunately you have the small 5/8” quill which does present a few problems. Adding an adapter arbor will prevent the ejection pin from working and it will not eject the plug that is left in the cutter after drilling a hole. This is a major pain as you would have to remove the rota broach from the arbor after each hole drilled. If there is enough material to safely machine it out to the more popular 3/4” Weldon shank broaches, that would be a much better option, as you would retain the ejector pin feature. Also your drill as shown is designed for 1” depth of cut broaches. You would need the riser block assembly to use 2” depth of cut broaches. This block is a spacer for the bottom arbor guide assembly. Another option may be to keep an eye out on eBay for the 3/4” arbor.
    hope this information may help you.

    Does seem difficult to machine or have machined, especially if it could be welded on. Does the currently installed endmill holder self-eject? Could it be modded?
