A countersink is an angle. A flat bottom is a counterbore.

You can buy a cutter the size of your outer diameter, and a pilot the size of the inside.

Frankly, I would suggest simply trying to do it with plain old twist drills. Once you put the screw in you wont be able to tell the difference.

These counterbore sets are great to have around, and the old-school factor is definitely cool; however, this particular set would only be worth it if the price is around $150-$200

The fact that you can swap out pilot tips isn't actually very useful (in my case at least) because the fixed pilot counterbore sets are all made to standard and metric screw sizes already. You can pick up a new counterbore set of standard and metric for a total of ~ $100. I picked mine up from amazon here here and

its not hard. youll need a drill for the through hole and a 7/8" counterbore. Just take small steps and measure to make sure you dont over shoot the depth.

Like this one (but you will need the correct pilot for the though hole)
