Is there some sort of really large counter sink type drill bit or reamer or something that can be used to put a little bevel on finger holes, finger grooves and radiuses that are very small up to about maybe 3/4" (like a 1 1/2" hole)? I guess something w/ about a 90 degree point. prefer not to use a 1 1/2 drill bit as that would be a little long and ungainly, not to mention expensive.

Thx
 
The plumbing industry has deburring tools that'll go 1 1/2", however there used in a pipe threading machines, i use a fluted counter bore to break the edges on my holes.
 
Without knowing how you are going to use it, I would be taking a stab in the dark.

Fill me in as much as you can, and I'll find the tool.

It sounds like you may need a small grinding wheel with a 45* taper (which would add up to 90*), like a large countersink?

It sounds like you are using it on steel, right?
 
I got sanding drums. I have a blade with, fpr example a 1" hole fpr the index finger. I need basically something like a large diameter counter sink to easily and neatly cut tge shapr edges off the inside of the hole. Effin around with a san ding drum will only make a measy un even bevel in that hole.
 
Maybe I'm doing it wrong, but I use sanding drums and mounted stones all day long, and never thought of them as messy. If you want a single tool to do the job on a 1" hole, go to the hardware store and get a large round or tapered stone that has a 1/4" shank. Chuck it in the drill press and it will chamfer/de-burr the holes in a single press. The problem is that it may wear down after a few holes and need re-dressing.

Something like these might be what you want:

Yup. That's kinda what I was thinking. Depending on how many you plan to do, you can use different equipment. I would think that most auto parts stores carry die grinders and their grindstones of every shape and grit.

Depending on how much and how accurately you wanted to break the corners, you could roll some wet/dry into a cone.
