This disc cutter set allows jewellers and craftspeople to produce crisp, clean dog-shaped blanks from sheet metal. The set includes a solid steel die block and four matching punches, all machined from tempered carbon tool steel for repeated use.
The four punches create blanks in distinct sizes: 6.18 x 10.52 mm, 8.41 x 15.34 mm, 11.36 x 19.24 mm, and 15.14 x 25.76 mm. For optimal performance and to preserve the cutting edges, use with a cutting lubricant on non-ferrous metals up to 18 gauge (1.02 mm). Annealing the metal beforehand is also recommended.
Use this set to create unique pendants, charms, earrings, or decorative elements for larger metalwork projects.

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.
