I need to cut small (1/8-inch or less in diameter by 1/4 to 1/2 inch in length) slots in 1/8 to 1/4 inch thick brass bar and/or sheet stock. I have a drill press, but not a dremel. What options are out there? I currently drill several small holes along the desired mark, then file out the holes to connect them into a slot (using small files, which takes a while). The resultant slots never look very good, but are functional. Other than stamping (which I don't have means to do), I haven't found a bit or tool small enough to do these cuts cleanly. Thanks for any info. Paul
