Hiya

I am wanting to drill some stones i have polished (they are beach/river stones), and am about to purchase this

Pillar Drill 5-Speed Hobby Model 583mm Height 330W/230V SDM30: Amazon.co.uk: DIY & Tools

But just want to make sure I am buying the right bit of kit for this... Does anyone have any helpful hints for me? I won't be drilling longways through the stone, just a simple hole at either end. I do know i need Diamond drill bits.

many thanks in advance!
