I use them in a drill press, or with a hand drill. The Microstops I 
purchased from Ray Lawrence, email  RL100W at aol.com use a 1/4-28 threaded 
cutters. Cutters come with different countersink angles, 82,  120, 130 
degrees, 100 degrees is a common angle for aircraft screws and rivets.

There is a collar, collar locking ring, set of teeth and a skirt. The 
collar is threaded and allows you to set the point that the cutter extends 
below the skirt. The skirt rests on the surface of the material you are 
going to cut. The adjustments are in .001's of an inch.

You set the depth using a sample of the same material that you will be 
cutting. It is best to purchase the screws and or rivets first then you can 
measure using the actual parts and countersink angle.

I have four Microstops, each is setup with a piloted different cutter:
Dzus countersink
8-32 100 degree Flathead screws
6-32 100 degree Flathead screws
2-56 100 degree Flathead screws

I use a vernier caliper to measure the depth of the face of the screw or 
rivet below the surface.
