This disc cutter set produces clean, repeatable spinning-top shapes from non-ferrous metal sheet. The set includes a solid steel die block and four matching punches, all machined from hardened and tempered tool steel to maintain a sharp cutting edge.
To operate, slide your metal sheet (up to 18 gauge / 1.02 mm) into the die block, position the corresponding punch into the aperture, and strike it firmly with a brass or nylon mallet. Using a suitable cutting lubricant will ensure a cleaner cut, reduce burrs, and prolong the life of the punches.
This tool is used by jewellers and metal crafters to create components for pendants, unique earring drops, and other decorative elements from silver, gold, copper, and brass sheet.
Cuts four distinct spinning-top shapes from non-ferrous sheet metal up to 18 gauge (1.02 mm).
Block and punches are machined from hardened and tempered high-carbon tool steel for durability.
Includes four punch sizes: 10.27x15.97, 12.84x19.14, 15.4x22.29, and 16.9x24.92 mm.
The solid steel die block measures approximately 64 x 89 mm (2.5 x 3.5 inches).
Each punch is approximately 38 mm long with a sharp cutting edge and a beveled striking end.
Only 5 left at the benchSame-day Birmingham dispatch on weekday orders before 2pm.
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.
