With 11 graduated hole sizes ranging from \u003cstrong\u003e4mm x 3.2mm up to 14mm x 11.2mm\u003c\/strong\u003e, this block covers a broad range of bezel-setting needs in a single compact tool.\u003c\/p\u003e\u003cp\u003eOtto Frei also offers oval bezel blocks in \u003cstrong\u003e75% and 60% ratios\u003c\/strong\u003e. The 75% ratio is historically popular and more closely matches faceted gemstone shapes, while the 80% ratio has become the preferred choice for cabochon work.\u003c\/p\u003e\u003cp\u003eBezel blocks are an essential bench tool for quickly forming precise bezel settings for faceted stones and cabochons. These Italian-made bezel blocks are crafted from specially hardened steel for durability and accuracy. A matching oval 17° punch is included.
