28 Degree 10 Hole Collet Block/ Plate and Punch Set, Black Carbon Steel, 4-18mm
For jewellers and stone setters forming or truing conical collet settings. The ten tapered holes and conical punch shape each collet to the same 28-degree taper, so a batch of settings comes out consistent.
Key features
- Fixed 28-degree angle, clearly marked on the block's ground face for accuracy.
- Ten tapered collet holes from 4mm to 18mm in diameter.
- Machined from a solid block of hardened carbon steel for workbench stability.
- Includes a steel punch with a conical tip to form the collet down into the hole.
Who it's for
A practical addition to the workshop for UK bench jewellers, silversmiths and stone setters who make their own collet settings. It also suits students and apprentices learning to form collets and bezels.
