I have a 4" Diameter by 1" piece of Aluminum that I need to make a 1.18" hole in. This will not just be a one time thing, I will need to do several of these.
My Lathe is a Heavy 10
The first time I did it I just drilled a small hole and enlarged it until I could get my boring bar in and then bored it out. That was pretty time consuming so I am looking for a faster way. I see a 1" drill bit with 1/2" shank is available but that also seems like it might be time consuming, unless I could jump from say a 1/4" hole to the 1" bit, but that seems highly unlikely. Anyone have experience using that large of a drill bit?
My other thought was to get a 1" or 1.12" end mill and use that, but my only problem is holding it. My jacobs chuck can't hold an endmill that large, although I do have a QC toolpost holder for a MT3. (provided I could find a 1" to MT3 End Mill) Would holding an end mill in the tool post or chuck work for making a hole that large? (material turning instead of end mill?)
Thanks
