    Default Spade drill holder

    I just got gifted some spade drill tips. I would like to machine my own holders. I got a close up photo of one off of Goggle. My question is has anyone machined up their own spade drill holders?

    There are many different styles of tips. It depends which ones you have.

    If you subscribe to the Magazine, there was an article about making the holder for whatever style the author had. Prolly a couple years ago now.

    If they are 1/4" hex, take $ 10 to HD, get a Irwin 12" extension with a quick release clutch. I had to drill 20 ea. 1 1/2 holes 6" deep in cherry, no problems except for a sore wrist.

    I think he is talking about metal spade drills, which are a lot different than wood spade drills.

    Not sure if this is the article that you are thinking of, but a quick search of the article index found this:


    Spade Drill Holder Don Wiederhold Shop Accessories HSM Vol. 34 No. 1 Jan-Feb 2015 24

    I don't know if I have that particular issue so I could not look to see the details, but it sounds like what you are after.
