This disc cutter set produces clean, consistent square blanks from non-ferrous sheet metal. The die block and seven matching punches are machined from hardened, tempered high-carbon tool steel for durability and a sharp cutting edge.
To use, place your annealed sheet metal (up to 18 gauge) into the die block. Insert the corresponding punch into the slot and strike its beveled end firmly with a brass hammer. The set includes punches for creating squares of 6x6, 8x8, 9x9, 11x11, 13x13, 15x15, and 16x16 mm. Applying a suitable cutting oil will improve the cut quality and prolong the life of the cutting edges.
This tool is typically used by jewellers for creating bezels and decorative elements, model makers fabricating precise components, or crafters producing custom tags and blanks for enamelling.
Includes seven square punches: 6, 8, 9, 11, 13, 15, and 16 mm.
Block and punches are machined from hardened high-carbon tool steel.
Cuts non-ferrous sheet metal up to 18 gauge (1.02 mm) thick.
The solid steel die block measures approximately 76 x 76 mm (3 x 3 inches).
Use with a brass hammer and cutting lubricant for clean cuts and longer tool life.
Only 5 left at the benchSame-day Birmingham dispatch on weekday orders before 2pm.
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.
