Jordan, hole saws are OK. I used to sell stuff like that. The secret, if you can is to secure the workpiece if it is small enough to the drill press table. Go slow and easy as suggested, use plenty of oil and set the drill press speed real slow. They do make these for metal cutting, Starrett brand is amongst the best. You can buy them in 1-3/4". Another tool is a flycutter, which will do the job. If this is somewhere say on the side of your carrier, I think you may find that a holesaw will want to skip all over. They need constant equal pressure and a firmly mounted workpiece. Ialso like richards idea odf a series of holes, punched out and then cleaned up with a die grinder. Certainly a lot of work but doable. I guess theres many ways to get from point A to point B, just depends on your resources.
