This steel disc cutter set precisely shapes curvilinear triangles from sheet metal, ideal for consistent geometric jewellery components.

What it does

This tool punches clean, uniform curvilinear triangles from sheet metal up to 1mm thick. The precisely machined punches, crafted from hardened tool steel, ensure crisp edges and repeatable results. Its integrated die block provides a solid base, eliminating the need for separate support and guaranteeing accuracy with every strike. This method efficiently creates symmetrical blanks, replacing time-consuming hand-sawing for earring and pendant production.

How to use it

  • Place sheet metal onto the die block.
  • Position punch and strike firmly with a hammer.
  • Clean punches after use for longevity.

Who it's for

This cutter is an essential for UK bench jewellers and silversmiths needing to produce geometric earring blanks or decorative components. It’s also valuable for jewellery students and craft makers looking for a faster, more accurate alternative to piercing saws for small-run production of consistent shapes.

What's in the box

One 4-punch curvilinear triangle steel disc cutter set in 4 sizes (15-22 mm).

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.
