This disc cutter set allows you to punch four distinct 'sparkle star' shapes from non-ferrous metal sheet. The set includes a solid steel die block and four corresponding punches, each made from hardened and tempered carbon tool steel for durability and a clean cut.
The die block measures 3 x 3 inches (76 x 76 mm), providing a stable platform for striking. The four punch sizes are: 10.29 x 13.83 mm, 12.41 x 16.67 mm, 15.9 x 21.37 mm, and 17.65 x 23.73 mm. The system is designed for use with soft metals up to 18 gauge (1.02 mm). For best results and to prolong the life of the cutting edges, we recommend using a cutting lubricant and a soft-faced hammer (such as brass or nylon).
Typical applications include:
Creating unique pendants and charms for jewellery.
Producing decorative metalwork elements for craft projects.
Fabricating custom components for model making.

Our steel letter, number, and design punches are heat-treated to strike non-ferrous metals: silver (sterling, fine), copper, brass, bronze, aluminium, gold. Striking hardened steel will damage the face. For pewter and very soft alloys, use light strikes.
What size impression do I need?
1–2 mm for ring shanks and small pieces (initials, hallmark-style); 3–4 mm for pendant backs and signed plaques; 5 mm+ for presentation pieces and stamped jewellery components. Bigger is not always better — a clean small mark reads better than a struggle with an oversized one.
What do I strike it with?
A 1–2 lb brass mallet on a polished steel bench block. Do not use a steel hammer — it will deform the punch over time. One firm strike beats two soft ones for a clean impression.
How do I keep the punch sharp?
Polished punches stay sharp for thousands of strikes if you are hitting cleanly on a flat block. If the face starts blurring impressions, polish lightly with 600-grit emery, then a buffing mop on a polishing motor. Replace before the face deforms further.
