This disc cutter set allows you to punch clean, consistent five-pointed star shapes from non-ferrous metal sheet. The set includes a solid steel die block and five corresponding punches, all machined from tempered, high-carbon tool steel for durable cutting edges.
To use, place your sheet metal (up to 18 gauge) into the die and strike the corresponding punch firmly with a mallet or hammer. The five included punches produce stars in approximate sizes of 8x9 mm, 11x12 mm, 14x15 mm, 17x18 mm, and 20x21 mm. Using a cutting lubricant will prolong the life of the tool.
This tool is used by jewellers and craftspeople to produce uniform components for pendants, charms, earrings, and decorative metalwork.
Punches and die block are machined from hardened high-carbon tool steel.
Five punches create stars measuring approx. 9, 12, 15, 18, and 21 mm point-to-point.
Cuts non-ferrous sheet metal such as silver, copper, and brass up to 18 gauge (1.02 mm).
The solid steel die block measures approximately 76 x 76 mm (3 x 3 inches).
Ideal for creating consistent star-shaped blanks for earrings, pendants, and embellishments.

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.
