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.

What's in the box

Set of 4 steel triangle disc cutters (9x11mm, 12x14mm, 16x18mm, 23x25mm) and 1 steel die block.

Common questions at the bench

What metal and thickness can it cut?
Check this product's description for the metals and any maximum thickness it gives, and stay within them. If it gives none, keep to thin, soft, non-ferrous sheet. Cutting sheet that is harder or thicker than the cutter is made for can chip or blunt the punches and the die.
How do I cut a clean blank?
Stand the cutter on a solid, flat surface such as a steel bench block and check the sheet lies flat where it should. Set the punch with its cutting end to the metal and strike it squarely and firmly with a hammer, or a mallet with a hard face; a nylon, wooden or rubber face can be dented by the punch. One firm, square blow gives a cleaner edge than several light or glancing ones.
Will the blank need finishing?
Check each blank. Smooth any burr or sharp edge with a file or fine abrasive paper before the piece is worn or finished, and if a blank has bowed slightly in the cut, flatten it with a mallet on a bench block.
How should I look after it?
Use it only on the sheet it is made for, wipe the punches and die clean after use and store them dry, with the cutting edges kept from knocking against other tools. If a punch sticks, tap it back out straight rather than levering or twisting it.
