I've done some trials on leftover pieces, they do not seem to be prone to cracking. On the deck they are 1" thick on a 1" mortar bed, they are well supported, so I think they will be fine.
I have a garden hose ready to go.

Normal flagstone is easy to drill, somewhere between a soft brick and cured cement. These stones are from China, so they aren't the flagstone I'm used to. They are extremely hard. Harder than any stone/concrete I've ever had top drill.
I am going to start by finding a Bosch SDS drill, then buying a high quality SDS bit.
This looks like a very good deal. I've seen a bunch of tools from this place that were 'reconditioned'. They all looked and worked like a new tool.
