The older drill presses had a quill stop the was a piece of threaded rod with jamb nuts that when set right would stop the depth at a precise spot. The newer drill presses have a rotary device with a big wing nut that is used to stop the quill. I have a delta that seems to be a fairly good big box store drill press that has the new method. I decide to set it up to trim 223 brass to length, and bought a Redding tool to make this happen. The new way is so sloppy brass was never even close to the same length. I am not a fan of the new drill presses. A neighbor has an older Clausing that I want so bad I can taste it but he won't sell or trade it to me.
