Core drill question

[thezappa]

So I bought a core bit (a dry diamond one no less). I’ll borrow an SDS drill since what I’m using it for is for 1 hole, a vent for the tumble dryer.
The questions I have are what size arbor do I need, and what else do I need?
I’m trying to do this as cheap as possible so if I can get away without spending on loads of extra bits that’s all good.

This is the bit I have:

This is the size of the threaded section at the top:

To be honest if you wanted to do it as cheaply as possible hire the core drill bit and accessories from your local hire shop.

Is it possible you can return the bit you've purchased?

Unfortunately no. I bought it ages ago. It was £17 so not the end of the world. I mistakenly bought it and didn’t realise I needed extra stuff.

This looks like the one an ABDCA3 SDS ADAPTOR 10MM X 115MM I'm not sure where you'd get it on it's own at bricks and mortar stores, but you might want to look at getting the kit that also has a guide bit that goes in the adaptor (makes it easier to use), and that looks to be slightly more readily available

Thank you. I have seen that kit but I had hoped I could get say 1 extra ‘thing’ but kept reading about ‘drifts’ and got a bit confusing.

If I could offer a bit of advice, once the core drill has made a bit of progress in the brick remove the pilot drill and then continue drilling with the core drill. I agree with @JRJ, you want a drill with a safety clutch as it will catch numerous times. Also if you have cavity wall insulation then you'll have two sets of bricks to go through and depending on the type of insulation you'll either have a snow storm or get the drill tangled in the fibre insulation.

Thank you, and noted.
I’m drilling through single skin brickwork, a division between the old garage (now utility and the other garage). The depth of the bit should be more than the depth of the bricks.
I will likely hire a drill, the local place has some beefy Makitas that will do the job.

A drift key is just a means of knocking out the drill bit from the adapter, they fit together by friction as opposed to a grub screw or similar.

Thank you. Seems a drift key is slightly superfluous.
