cut off the end

EDIT: I have never seen an adapter for a standard chuck to fit your variable spade bit shank. Really, if you can't use it otherwise and it is not on loan from someone else, cut the end off.

Yeah, just cut off the end. Just so people know, the square end on the drill shank fits in old hand drills called a "bit brace" style crank drill. You should easily be able to cut it with a hacksaw.

yes, cut the end off, but also grind 3 or 6 flat sides, it holds better.

Flats would be nice but be careful. If the flats aren't exactly right the bit will be off center. This type of bit will be very unhappy if it isn't centered perfectly in the chuck.

yeah, i'm not grinding any flats, too dangerous, plus the chuck on a drill press has a pretty tight grip so circular should be fine

Why not get a 1/2" chuck? I've got one on my 3/8ths drill, it's a cheezy craftsman, works great.

Which do you have? A 1/2" or a 3/8"? Or did you put a 1/2" chuck on a drill motor designed for a 3/8"?
The 1/2" chuck won't make a difference with this bit, it still won't grab the shaft evenly, if you are suggesting using the larger chuck.

I put a 1/2" chuck on a 3/8ths drill. Square shank, your right, it still wont grab it right because it's got 3 jaws not 4. Good catch Willard. I don't know if any one makes a 4 jaw chuck for a eletric drill. :shock:
