I need a tool and might have to make it.

I need a tool to evenly round off the edges of the inner face of a hole in 1095.
I was thinking of shaping it sprt of like a spade bit out of hardenable tool steel but all I have is 1095. It's to round out a 1" hole... I'm thinking if i'm careful I can make it out of 1095. Will hardened 1095 shape annealed 1095 ?

I would prefer 01 or D2 but I think tracking down a small piece of that steel in my area would not be very cost effective after shipping costs.

I thought of buying a bit that would do the job but idk if such a thing exists.

Heres a picture lol...

Carbide round over bit for a router. It might work in a drill press.
I've been using different size Uni-Bits (cone shaped) to chamfer holes for at least 20 years which give pretty much the same results but not an even arc. You could chamfer both sides and hit it with paper.

If I were doing this project, I'd do it with my metal lath. Would be really simple I think. You might doing it on a wood lath with a little patience.

Definitely Uni-bit. Some guys call it a step bit. I use them all the time. Lennox brand is the best. Just don't overheat it. They last a very long time

When I first started smithing almost every time I went to the shop to make something it seems that I had to make a tool first to be able to make what ever I had planned. After a couple of years I had a lot of tools. From time to time I still have to make a tool.
 
I was considering a router bit but didn't think I could find one that size. I'll have a look.
Also considered a lathe. I have an industrial metal lathe here but it hasn't been fired up in years.
I've been using unibits to make the original hole but it doesnt make a very even edge. I was hoping for a tool that could knock the corner edges off then I could finish it by hand sanding possibly.
Thanks this does give me a few ideas!
 
IF you're going to try it.
I was at Lowes today and was standing right in front of the round over bits. They have 1"x 1/8" radius and 1"x 1/4" radius. As far as available size, I have panel bits that are 2" or bigger. Take a look in the Grizzly catalog if you want an education. I've never tried it but I'd be careful with one in the drill press, I've had carbide chunks fly off in my large router while cutting oak. But on the other hand, I use carbide tooling on my mill so who knows ? Make sure your work is very secure and can't move around.
