Round Bezel Block Set-4 Degrees-10-15-20 & 25-4 Rows 3mm to 8mm

The Round Bezel Block Set from OMO is a professional-grade tool for fabricating round bezels with precision wall angles. Designed for jewelers and metalsmiths who require consistent, repeatable results, this set provides four distinct taper angles — 10°, 15°, 20°, and 25° — allowing you to match the ideal wall angle for a wide range of stone settings. The hardened steel block features eight graduated hole sizes ranging from 3 mm to 8 mm, giving you full coverage across common round stone diameters in a single tool.

Each set includes four matching punches — one per angle — so you can select the exact angle needed for your bezel wall without switching between incompatible tools. This set is Italian made and built to the standards expected by professional bench jewelers.

Also available in a smaller size range (3 mm to 7 mm); see part number 127.085. The difference between the two sets is minimal.

Replacement punches are available separately.
