For punching square blanks that all come out identical — bezels, decorative elements, tags and blanks for enamelling, plus precise components for model making. Seat annealed sheet up to 18 gauge (1.02 mm) in the die block, insert the punch — squares of 6, 8, 9, 11, 13, 15 or 16 mm — and strike the bevelled end firmly with a brass hammer.
The block and all seven punches are machined from hardened high-carbon tool steel for durability and a lasting edge. A drop of cutting oil before each cut improves the finish and prolongs the life of the cutting edges.
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.
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.
