Disc cutter........metric or imperial?

[taylordebs]

I think I have talked myself into getting a swanstrom disc cutter, they do a metric one for £30 more but sizes are virtually the same so what would be the advantage of getting the metric one please? thanks

Check out the size difference, I went for imperial because I think imperial is slightly larger, for instance I wanted mine to cut bottoms for bezels for 5mm stones and the imperial one was very slightly larger than the metric to enable me to have a squarer sided bezel. when you cut with a disc cutter it leaves slightly bevelled side, well mine does anyway, so trying to get a neat finish to the bottom corner of bezels would be impossible with the metric one.
