Hello there -- I'm new to this forum (and machining in general), but I thought I'd throw this out there and see what people have to say.
I'm trying to get tooled up for cutting miters on bicycle tubing without breaking the bank. Also, I'm working out of a maker space so working with what's available there.
From what I've been able to learn from more bicycle-specific sources, regular hole saws should work fine as long as the setup is rigid enough to withstand side loads when the saw tries to wander off. The shop I'm in has a pretty heavy duty Grizzly G0793 that comes with an MT#4 spindle and MT#2 and MT#3 adapters, as well and drift pin for tool removal
The more rigid hole saw arbors I've seen have a 3/4" straight shank. I see that there are collets that will directly insert into a morse taper, which would probably be ideal for me because I could just buy a 3/4" one and be good to go (I think). But it seems like these tend to be used on a lathe with a draw bar. Is there a good way to use this style of collet in a drill press / milling machine situation?
If not, any suggestions for a relatively inexpensive collet chuck or something else? Again, all I really need is to be able to hold a 3/4" straight shank in a MT2, MT3, or MT4 spindle.
Thank you!
