Default Routing a 1.25 hole at 20deg from vert.

I am attempting to make a series of 1.25 dia. holes in a 3/4" board 48 x 12" wide. I have tried using a 1.25 dia. Forster bit but I get a lot of tearout on the opposite when the bit exits. I need to bore from both sides so I can't have any tearout.
Hoping to make a wine rack with this board.

I was hoping to use a router with a face plate angled 20 deg. mounted to the router base but when I workout the dimensions needed the router bit becomes too long and I am unsure how I would be able to make a jig of some sort to hold the whole thing.
My smallest router has a base of 2 1/2" from the side to the center and has a 1/4" collet.
Looking for any suggestions.
Mike

I think a 1.25" brad drill or a holesaw on a drill with suitable attachment would be a lot more suitable than using a router.

Pls watch..

Hot glue or clamp a scrap MDF on the other other side to reduce tearout.

A slight modification so the router could "plunge" is all that is needed.

Another easier method would be to cut two wedges and fasten them to the routers base with double sided tape. I would also tie them together with a piece across the end. Odds are you will need a collet extension for this method.

As Reulet said go with a hole saw it shouldn't give any tear out.

Routing will be tough with a 1/4" router. I would use a forstner bit with a sacrificial board underneath as mentioned erlier in this post. If you tru to modify your router base it could be hard to keep it at a constant angle to the work piece.

I think the hole saw would have been the right thing if I had a 1 1/4 hole saw at the time. But, trying the forster bit may have ruined the board as the last try produced 6" of railroad tracks across the whole board!!! Thanks for your help.

Are you using a drill press or drilling by hand?

I'm using a drill press. I did buy a 1.25 hole saw and an adaptor for $26 for a one time use! It was the right tool and worked great but now I have to figure out how to repair the railroad tracks.
