1.The clamping, which makes certain, that your silver does not wander causing your disk to be incomplete.
That said you do have fingers to do the job for you, but you need to concentrate.
2. The more expensive sets have slightly tapering stems on their cutting punches, which means they can be removed more easily on completion of the cut. The cheaper sets require an additional rod to tap the cutter right through, because it gets stuck in the metal sheet.
I think you would find a 25mm disk quite difficult to create unless you have a hydraulic press. My biggest cutter measures just under 16mm. After that I scribe the disk and use a saw.
Lastly you need a supplier who will accept returns, so I would stick with Cookson, or Walsh. Dennis.
