Category: Jewellery Making Tools

For punching five-pointed star blanks in matched sizes — components for pendants, charms, earrings and decorative metalwork where every star has to match the last. Set non-ferrous sheet — silver, copper or brass up to 18 gauge (1.02 mm) — in the die and strike the punch firmly with a mallet or hammer. The five punches cut stars of approximately 8x9, 11x12, 14x15, 17x18 and 20x21 mm.

The die block and punches are machined from tempered high-carbon tool steel for durable cutting edges, and the solid 76 x 76 mm (3 x 3 inch) block sits square under the strike. A cutting lubricant prolongs the life of the tool.

  • Punches and die block are machined from hardened high-carbon tool steel.
  • Five punches create stars measuring approx. 9, 12, 15, 18, and 21 mm point-to-point.
  • 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 76 x 76 mm (3 x 3 inches).
  • Ideal for creating consistent star-shaped blanks for earrings, pendants, and embellishments.

Alexander C. ★★★★★

The 8mm punch cut through copper sheet like butter on my first try. Each star came out crisp and identical, perfect for a matching pair of pendant blanks.

George ★★★★★

I punched matching stars in 20 gauge copper sheet and the cuts came out clean with barely any burr. The 8–21 mm range covers the earring sizes I use most. Being able to hammer out identical stars instead of filing each one by hand saves me so much time.

Julian C. ★★★★★

The five punches give a really useful spread, and the stars come out perfectly matched — I did a set of silver earrings with the 12mm and they’re identical. Steel’s held up through a dozen copper blanks without any sticking or dulling.
