Create precise triangle metal blanks for jewellery with this professional steel disc cutter set.

What it does

This tool precisely cuts equilateral triangle shapes from sheet metal using a sharp punch driven by hammer impact. The hardened carbon steel punch and die ensure clean, repeatable cuts through non-ferrous metals up to 18-gauge. Its robust 3-inch steel die block provides a stable, flat surface for consistent results, reducing filing and setup time.

How to use it

Position metal sheet over the die opening.
Align punch and strike firmly with a hammer.
Clean punch and die regularly for optimal performance.

Who it's for

Essential for UK silversmiths, jewellers, and pattern designers creating geometric components. This set streamlines the process for professionals and serious hobbyists, replacing tedious hand-cutting and offering consistent shapes for soldering and assembly.

Common questions at the bench

What weight hammer should I start with?

For most bench work, 4–8 oz is the sweet spot. Lighter hammers (2–4 oz) suit fine detail and chasing punches; 6–8 oz suits forging and texture work. Avoid anything over 12 oz unless you specifically need a raising hammer.

Can I use this on annealed silver and copper?

Yes — these hammers are designed for non-ferrous metals: silver (sterling, fine, britannia), copper, brass, bronze, and aluminium. The polished face will not transfer marks to clean annealed stock when used correctly. For mild steel work, use a separate hammer.

How should I care for it?

Wipe the face down after each session to prevent any tarnish from work residue marking your next piece. If the head develops nicks, polish them out with fine-grit emery and a buffing mop — a marked hammer face transfers marks to your work.

What is in the box?

One hammer with the head and handle fitted, ready for the bench. Polished faces are protected with a thin oil film — wipe before first use.
