This disc cutter set allows for the precise and repeatable cutting of kite-shaped blanks from non-ferrous sheet metal. The die block and four matching punches are machined from hardened high-carbon tool steel, ensuring clean cuts and a long service life when used correctly.
To operate, simply place your annealed sheet metal (up to 18 gauge) into the die slot. Insert the desired punch and strike it firmly with a brass mallet to shear a clean blank. The set includes four distinct kite sizes: 14.69x23.06mm, 16.19x25.4mm, 17.69x27.75mm, and 19.2x30.09mm. Using a cutting lubricant is recommended to extend the life of the cutting edges.
This tool is suited for jewellers creating pendants, earrings, or decorative elements. It is also useful for model makers and craftspeople who require consistent geometric shapes from copper, brass, silver, or gold sheet.
Punches and die block machined from high-carbon tool steel for durability.
Includes four kite-shaped punches: 14.7, 16.2, 17.7, and 19.2 mm widths.
Cuts non-ferrous sheet metal up to 18 gauge (1.02 mm) thick.

Ideal for creating consistent, repeatable kite-shaped blanks for jewellery.

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.
