Form and true conical collets and bezels with this 28-degree, 10-hole collet block and punch set. Designed for shaping collet settings in silver, gold and other non-ferrous sheet at the bench.

What it does

This collet block has ten holes tapered to a 28-degree angle and comes with a steel punch that has a conical tip. Drop a soldered cone blank or a short length of tube into the hole it fits, then tap the punch down inside it to form or true the collet to the block's taper. Moving through the sizes lets you stretch or shrink a collet gradually, so a batch of settings comes out with the same 28-degree taper. Its solid carbon steel construction provides a stable platform for accurate work.

How to use it

  • Choose the hole your cone blank or tube section sits part-way down.
  • Seat the blank in the hole and place the punch tip inside it.
  • Tap the punch with a hammer to form the collet to the 28-degree taper; anneal and work gradually.

Who it's for

Ideal for bench jewellers, silversmiths and stone setters who make their own collet settings for round faceted stones. It takes the guesswork out of forming a true cone by hand, giving consistent settings for intermediate and experienced makers alike.

Common questions at the bench

What is it for?
Forming and truing cone-shaped collet settings to the taper of the block. The setting sits in the hole it fits and the punch is tapped down inside it, shaping it to the same angle.
Which hole do I use?
Start with the hole your setting sits part of the way down. Move through the holes a step at a time to stretch or shrink it gradually, rather than forcing it in one go.
Does the metal need annealing?
Annealed (softened) metal forms more evenly and is less likely to split. Tap the punch lightly, check the setting often and anneal again if the metal starts to resist.
How should I look after it?
Wipe the block and punch clean after use and store them dry, with the punch tip kept from knocking against other tools.
