This disc cutter set produces clean, consistent heart-with-arrow shaped blanks from non-ferrous metal sheet. The set includes a solid, hardened carbon tool steel die block and three matching punches. Operation is straightforward: place your sheet metal in the slot, insert the corresponding punch, and strike it firmly with a mallet to eject a perfectly formed blank.
The three punches create shapes measuring 21.24 x 22.63mm, 27.08 x 28.86mm, and 34.29 x 34.03mm. For optimal results and to prolong the life of the cutting edges, we recommend using a cutting lubricant like Bur-Life and annealing your metal before punching. Always work on a solid, stable surface and use a soft-metal or nylon mallet to strike the punches.
Typical applications include: • Creating pendants and charms for jewellery. • Producing consistent decorative elements for larger metalwork projects. • Making custom tags or embellishments from copper and brass sheet.
Cuts three heart-with-arrow shapes: 21.2mm, 27.1mm, and 34.3mm (approximate widths).
Includes three punches and a matching hardened carbon tool steel die block.
For non-ferrous metals up to 18 gauge (1.02mm) like silver, copper, and brass.
Punches are precision-ground with a sharp cutting edge and a bevelled striking end.
The solid steel die block provides a stable base for clean, repeatable cuts.
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.
