I used to use every tool they ever invent and have rotary files and super air power but as I ripen a little lean to easier and simpler, cheaper and faster. This is a version of this but get a bi metal with more teeth, they make a couple versions but this size bit works fair and lets it be done battery drill and chances are can use the bit for another couple dozen holes. The uni bit would be great as a starter to seat the holesaw.
