Curvilinear Triangle Disc Cutter Set — 4 Steel Punches, 4 Sizes 15–22 mm, Jewellery Making

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.
