They are quite expensive, if you're not going to use a combi's other functions and you have a smaller SDS anyway you might be better off with a dedicated core drill for around half the cost.

You don't want to be using an SDS for core drilling. The clutch is too strong and won't cut in soon enough if the core bit jams.

The Milwaukee dedicated core drill is a fantastic bit of kit and lighter than the ddm3. I have used the Milwaukee core drill, and I own a DDM2. Both are fantastic drills but the DDM2/3 are very heavy if you are holding it up.

That's very true IF you use dry diamond core bits in a SDS but TCT core bits should be used with a SDS and with the hammer on so you get much less chance of snatch as the cutting teeth are tiny and the bit is much shorter. Dry diamond cores are longer and as you know have large, blunt coated teeth of a steel cylinder which are designed to abrade rather than cut which is why you need a decent clutch to use them. Problem is most diamond cores come with a SDS adapter encouraging their misuse and that's just dangerous especially with the larger diameters, still if the drill is mainly for large cores I agree get a core drill.

I've got the Milwaukee core drill. Better priced than the DDM3 but a cracking drill. It's got a very light hammer action which can be used if the diamond core starts to jam, without damaging the core bit.
