This disc cutter set allows for the precise and repeatable cutting of shield-shaped blanks from non-ferrous metal sheet. The set includes a solid steel die block and four punches, all machined from hardened and tempered carbon tool steel for durability and a clean cutting action.
To use, simply place your sheet metal (up to 18 gauge / 1.02 mm) into the die slot, insert the desired punch, and strike the bevelled end firmly with a suitable hammer. The set produces four distinct shield sizes: 8.14 x 12.45 mm, 9.97 x 15.24 mm, 11.88 x 18.15 mm, and 13.86 x 21.19 mm. Using a cutting lubricant is recommended to prolong the life of the cutting edges.
Ideal for jewellers fabricating pendants and earrings, or for model makers and craftspeople requiring consistent decorative components from materials like silver, gold, copper, and brass.
Cuts four distinct shield sizes from 8.14 mm up to 21.19 mm long.

Suitable for soft sheet metals up to 18 gauge (1.02 mm).

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.
