Good afternoon. I am on the cadge for advice as ever! I wonder what you experienced and professional people use. I have a dreaded Dremel unit with a vertical drill stand. Apart from the lack of progressive speed control the vertical stand is a bit “hit and miss”. I also find it difficult to load the drill bit so it revolves perfectly round its vertical axis. Invariably it has a slight wobble which makes precise drilling impossible. I have had to drill undersize then broach out the hole using my horological broaches. This is hard work as these broaches are made to cut brass but struggle with the softer silver.
