Here's my Tatco squeezer with Avery dimple dies on the left and my countersink cage on the right. I got an ebay deal on 7 countersink cages and bits so I'll be able to adjust them individually and not spend time changing bits and readjusting for the correct depth for every job which you have to do if you only have one. When you adjust the countersink cage for depth, you loosen the retaining nut and rotate it one "sawtooth" to raise or lower it 1/1000th of an inch. You can see the interlocking sawteeth in the picture below.
