This disc cutter set creates clean, consistently sized bottle-shaped blanks from non-ferrous sheet metal. The set includes a solid, hardened steel die block and four matching punches, allowing for efficient production of components for jewellery and craft projects.
To use, place your sheet metal between the two halves of the steel block. Insert the desired punch into the corresponding aperture and strike it firmly with a suitable hammer. The hardened tool steel punches provide a sharp, clean cut. We recommend using a cutting lubricant to extend the life of the cutting edges. The four punch sizes are 11.46x17.36mm, 13.26x20.11mm, 15.94x24.19mm, and 19.68x29.91mm.
This tool is ideal for jewellers creating a series of pendants or earrings, silversmiths needing uniform shapes for fabrication, or model makers requiring specific metal components.
Includes four bottle-shaped punches: 11.5x17.4, 13.3x20.1, 15.9x24.2, and 19.7x29.9 mm.
Die and punches are machined from hardened and tempered high-carbon tool steel for durability.
Cuts non-ferrous sheet metal such as silver, copper, and brass up to 18 gauge (1.02 mm).
The solid steel die block measures approximately 64 x 89 mm (2.5 x 3.5 inches).
Produces clean, repeatable blanks for earrings, pendants, and other jewellery components.

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.
