DI160 = Bezel Burnisher Set for Stone Setting

18-Punch Bezel Setting / Burnisher Set This kit brings together 18 concave steel punches, precisely hardened and polished, ideal for closing round bezels around stones (roughly up to 5€“6 mm) without scratching or marring. Each punch is concave on the tip and arranged in a polished hardwood box with etched millimeter markings above each slot so you can see at a glance which size you're grabbing. How to use it (for hobbyists & bench makers): * Select a punch that is about 10€“25% larger than your bezel's external diameter (smaller stones need less wiggle room). * Clamp the bezel & stone securely (bench block, holding tool, etc.). * Use the concave face of the punch to gently rotate around the bezel edge, gradually pushing the bezel metal inward until it hugs the stone. * For harder metals or tougher settings, you can also carefully tap the punch with a light hammer to apply force in measured increments. Because the punches are polished inside, they're less likely to scratch your bezels, but for ultra-fine finish, you may want to polish the inside faces yourself before use.
