This disc cutter set allows you to punch four sizes of detailed butterfly blanks from soft metal sheet. The set includes a solid steel die block and four corresponding punches, each machined from hardened tool steel for clean, repeatable cuts.
The block measures 76 x 76 mm, providing a stable platform for your work. The four punches create butterfly shapes measuring approximately 22.2x17.4 mm, 18.4x14.4 mm, 15.0x11.8 mm, and 12.4x9.7 mm. For best results and to prolong tool life, use with a suitable cutting lubricant on annealed metal up to 1.2 mm (18 gauge) thick.
Use this set for creating charms, pendants, and decorative elements for jewellery, or for adding intricate details to model engineering and 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.
