This disc cutter set produces clean, repeatable teddy bear shapes from soft metal sheet. The set includes a solid steel die block and four matching punches, all machined from hardened and tempered carbon tool steel for durability and edge retention. The block's weight provides a stable base for accurate striking.
To use, place your annealed metal sheet (up to 18 gauge / 1.02mm) into the die and insert the corresponding punch. A firm strike with a brass hammer will shear a clean blank. The four specific punch sizes are: 12.97 x 13.33mm, 15.84 x 16.21mm, 19.59 x 20.12mm, and 25.24 x 25.82mm. Using a cutting lubricant like Bur-Life will extend the life of the cutting edges.
This tool is suited for jewellers creating charms and pendants, crafters making decorative embellishments, or model makers fabricating custom parts from brass and copper sheet.
Cuts four teddy bear shapes from non-ferrous sheet metal up to 18 gauge (1.02mm).
Block and punches are machined from hardened and tempered high-carbon tool steel.
Includes four punch sizes: 13mm, 16mm, 20mm, and 26mm (approximate heights).
The solid steel die block measures 76 x 76 mm (3 x 3 inches) for stability on the bench.
Punches feature a sharp cutting edge and a beveled end for clean hammer strikes.

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.
