Hi SimplyBea,
The individual holes on the
drawplate are not labelled with either millimeters or wire gauge size, so it would be tricky to use it to draw wire to exact wire gauges (whether American or British measurements). While it is designed for straightening, work hardening, and resizing wire, you would need to measure your wire with precise calipers or a wire gauge when done, to determine the wire gauge size. With 82 holes from .12mm to 2.5mm (roughly 30g to 10g), you should be able to get very very very close to every size in between that range.
