Collet Forming Block & 17° Punch — 12 Holes 3–19 mm, Black Carbon Steel Jewellery Plate

This 17-degree forming plate and punch set precisely shapes and refines jewellery settings for a perfect fit.

What it does

This tool allows for the controlled stretching or shrinking of collets and bezels. By striking the punch into the corresponding plate hole, you gradually manipulate the metal to achieve the desired diameter and depth. The precisely machined 17-degree taper on both the holes and the punch tip ensures consistent, repeatable results without distorting the setting's shape. The robust carbon steel construction and corrosion-resistant black finish guarantee durability for daily workshop use.

How to use it

• Select the correct hole size for your setting.
• Position the setting over the hole and strike the punch.
• Work metal gradually; clean punch and plate after use.

Who it's for

Essential for bench jewellers, silversmiths, and stone setters, this tool refines the process of forming settings. It's equally valuable for apprentices and students learning to create or adjust bezels and collets, replacing guesswork with precision. Pairs perfectly with your existing bench toolkit.
