Ring Stretcher Disc with Countersunk Holes This is a new disc for a ring stretcher. The disc inevitably wears out with years of use, and many people feel it's a waste to replace the entire stretcher. This disc is compatible with the ring stretchers I sell, but I cannot guarantee compatibility with other ring stretchers. The disc features a reversible design with a total of 16 countersunk holes. It is made from high-quality stainless steel, ensuring long-lasting use. Please note that this tool alone cannot be used to create coin rings. *We recommend annealing the ring with a burner to soften it before use. *There is a risk of scratching the countersunk holes due to metal burrs, so be sure to remove any burrs before use. 【Size】 Reduction Hole Sizes: 12.5mm ~ 28mm / 16 holes total Coin Ring Making Coin Ring Production Coin Ring Creation Kit
