what are they like to use? can they be used with a small type sds drill or is something with a bit more poke needed?

maybe a set like this

just curious really. i did once use a tct type core drill but i had to use it with a huge hilti drill. and it took bloody ages to get through the wall. was probably quicker to break through with a mash hammer, cold chissel and bolster

They are good on most materials, but you need a powerful drill. The drill should say in the instructions what the maximum capacity core can be cut with that drill.

If you want a proper set up then you are better off with an sds drill with a saftey clutch, using them without a safety clutch is not really a good idea.

Not quite right Chez.

If you want a proper set-up and you are doing a lot of core drilling.

Buy a non SDS drill with a clutch, SDS is no good for most core drilling as it will constantly slip.

Also with diamond coring you need a fair bit of rpm in relation to size

If you want a proper setup, buy a proper core drill

This one is for wet or dry cutting.

For most use though, a decent low geared drill like these
