The spade of the card suits, punched clean from sheet in four sizes: 18.76 × 12.52 mm, 20.11 × 15.03 mm, 26.81 × 20.04 mm and 30.16 × 22.54 mm. Blank matched pendants and tags, or cut decorative elements to solder onto larger pieces — the shearing action leaves little finishing work at the edges.
Both the 76 mm square die block and the punches are high-carbon tool steel, tempered for edge retention. Keep to non-ferrous sheet — silver, copper, brass — of 18 gauge (1.02 mm) or thinner, anneal before punching, and use a cutting lubricant; a crisp, clean shear depends on it.
Punches and die block are machined from high-carbon tool steel, then tempered.
Includes four spade punches: 18.8x12.5, 20.1x15.0, 26.8x20.0, and 30.2x22.5 mm.
Cuts non-ferrous sheet metal like silver, copper, and brass up to 18 gauge (1.02 mm).
The solid steel die block measures 76 x 76 mm (3 x 3 inches) for bench stability.
Slide sheet metal into the slot, insert the matching punch, and strike firmly.
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.
