I'm going to buy a drill press and I need a little advice. I'd like to use the drill press for occasional woodworking projects as well as for drilling holes in rocks. I want to drill small holes in rocks for things like eye hooks, but I'd also like to make circular cabs by using a diamond core bit.
Here's part of the description of some drill bits from Kingsley North:
The recommended minimum drill speed for these drill bits is 5000-10,000 rpm.
I'm considering this 10 inch Ryobi drill press:

The problem is, this drill press has a max speed of 3050 rpm.
The core drill has a recommended speed of 700 rpm and the drill I'm looking at has speeds of 570 and 900. Is that close enough?
Is there an affordable drill press that will work better for me? Do I need two separate drill presses for the different bits? Can anyone make a specific drill press recommendation?
Thanks,
Rob
Here's part of the description of some drill bits from Kingsley North:
Standard Diamond Drill Bits
Kingsley North → Lapidary Equipment & Supplies → Diamond Drills
Man made diamonds bonded to a durable music wire providing a positive clearance (kerf) allows easy drilling without jamming. Recommended operating speed is 5000 to 20000 RPM.
IMPORTANT!
Start hole by allowing only a minimum amount of drill tip to protrude beyond the collet or chuck jaws since shank size is only .020.
Once hole is started, adjust drill length as necessary.
Run at 10,000 rpm minimum or more.
