This disc cutter set allows you to punch three distinct mushroom shapes from soft metal sheet. The set includes a solid steel die block and three matching punches, all machined from hardened carbon tool steel for durability and a clean cutting action.
To use, simply place your sheet metal (up to 18 gauge or 1.02mm) into the die and strike the corresponding punch firmly with a mallet. The three punch sizes are 13.32 x 15.51 mm, 15.32 x 17.83 mm, and 17.89 x 20.84 mm. For best results and to prolong the life of the cutting edges, we recommend using a cutting lubricant and annealing your metal.
Ideal for creating unique pendants, charms, and decorative elements for jewellery or metal craft projects.

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.
