The Veritas were/are excellent cutters but unless they are re-designed, they need a pillar-drill or something similar.
As I no longer have one, I heard about a self-centreing plug cutter made by Hitachi that was equipped with spring-loaded pin, so it could be used in a conventional electric hand drill.
Bad news is, you can't get them in this country...... dunno why.
However, searching around I did find something similar at (sorry, boys) Rutlands made by Montana at about £25 for a set of three different sizes.
They were 'OK' and did the job but I soon found out that the cutting edges were not sharpened at all, and gave a raggy finish (good 'ol Rutlands). I took a diamond paddle sharpener to them and now they work fine.
So if you go for the Montana ones, be prepared to have to touch them up yourself.
