This disc cutter set allows you to produce clean, consistent rounded rectangle blanks from sheet metal. The die block and two corresponding punches are machined from hardened, tempered high-carbon tool steel, ensuring sharp cutting edges and durability when used correctly.
To operate, place your sheet metal in the die's channel, insert the desired punch into the matching slot, and strike the punch's bevelled end firmly with a jeweller's hammer or mallet. For the cleanest cuts and to prolong the life of the cutting edges, we recommend using a cutting lubricant and working on a solid, stable surface. This tool is designed for use with non-ferrous metals such as silver, gold, copper, and brass.
Use this tool for creating uniform pendant blanks, fabricating custom nameplates for models, or producing a series of identical components for jewellery collections.
Cuts clean rounded rectangle blanks from non-ferrous sheet metal up to 18 gauge (1.2mm).
Block and punches are machined from hardened high-carbon tool steel for edge retention.
Includes two punches for creating blanks measuring 22 x 34.75 mm and 25.4 x 42.85 mm.
The solid steel die block measures 125 x 75 mm, providing a stable base for striking.
Punches are approximately 38 mm long with a bevelled end for safe hammer striking.

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.
