Boring a hole in cast iron hand wheel
Hi all,
New to any form of metalworking. I am making a woodworking workbench and I'm looking to bore a hole in a hand wheel to fit 1-1/8" vise shaft. The only drill bit I have in that size is a spur auger bit, that's stated to be specifically for wood. I'm wondering whether I can use that in a pinch. I don't know what the bit is made from, but I'm pretty sure it's harder than cast iron. I have a 22mm HSS bit, so I can bore it to that size first. I will be doing this on a drill press.
Otherwise, what options do I have? I don't want to spend a lot on a bit I'll only be using once.
If it helps, my bit is this:

And the hand wheel I'm looking to get is this:

See if you can get a holesaw with that size pilot.
Here's an example -

Ah, so your idea is to drill all the way through? I'm not sure how thick it is - I can only tell visually from here (it's the 190mm I'm looking at) https://mcjing.com.au/cast-iron-hand-wheel.html
I was thinking of drilling just enough to be able to drive a pin through.
So the auger bit won't do?

I would suggest you ask if someone could bore it for you.

Will this with a 1/4" arbor work? It's on a drill press so the centre hole being larger shouldn't matter, right?

If you want reasonable accuracy on the centre hole an 8.5mm pilot would be better. You can get a reasonably priced pilot and just get the holesaw you need and can always purchase other holesaws later if needed. 1 1/8" is 28.575mm so the holesaw will need to cut a fairly accurate hole. Most state a 1 1/8" holesaw as 29mm so will that matter. Depends on how true to size they are as well.
Here's a Sutton so you will need the arbor to go with it.

I am with Pipeclay on this, I think that it would be better bored or perhaps drilled and then reamed if a particularly good hole is required. Holesaws in my experience aren't really round, but could have more than one milimetre runout for that size. There is a good chance that someone on this forum and with the required tooling lives not far from you, and would be willing to help you out. If you are going to tap that wheel 1 1/8", you want to hope that someone who already has the tooling will help you out as a tap that size will be $pendy, as will the drill bit if you can't get it bored out. Good luck

Boring
Where are you? If you’re in Sydney, or Northern Sydney ( or elsewhere) I can bore it out exactly for you on the lathe or you could post it and I’ll do it, no problem at all.

Confused now. Do you want to bore to tap 1 1/8" or bore to 1 1/8"?

Do youself a favour and get someone to bore it out. A hole saw or spade bit will give you a rough hole and won't be close enough in size - the fit on the shaft will be sloppy and you will not be happy with it. What is worse will be that there is likely no good fix for that so you will be up for a new handwheel.
We have/ had a member here called Ewan (goes by the user name of Ueee) who lives in the Canberra region, although he has not posted for some time. Send him a personal message and he might be able to help you out. With the right tools it is not a hard job to do.
