This disc cutter set allows you to punch four distinct large shapes from soft sheet metal. The set includes a solid steel die block and four matching punches, designed for creating clean, repeatable blanks for jewellery and craft projects. The punches are bevelled on one end for striking with a mallet or hammer, and precision-ground on the other for a sharp cut.
Constructed from hardened and tempered carbon tool steel, this tool is built for repeated use on non-ferrous metals like silver, gold, copper, and brass up to 18 gauge (approx. 1.02 mm). The die block is a stable 76 x 76 mm (3 x 3 inch) square. The four punch shapes measure approximately 17.99 x 21.35 mm, 23.86 x 15.26 mm, 21.33 x 17.82 mm, and 21.70 x 21.86 mm. For best results and to prolong the life of the cutting edges, we recommend using a cutting lubricant.

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.
