Diamond Steel Disc Cutter Set, 4 Punches, 13-29 mm, Jewellery Making Tool
This disc cutter set allows you to punch clean, consistent diamond-shaped blanks from non-ferrous metal sheet. The die block and four matching punches are machined from hardened carbon tool steel, ensuring sharp edges and durability for repeatable work in a professional or hobbyist workshop.
To operate, simply slide your sheet metal into the die, select the desired punch, and strike it firmly with a brass or nylon mallet. The set includes four precise punch sizes: 28.92x25.61 mm, 24.79x21.95 mm, 20.66x18.20 mm, and 13.53x14.00 mm. For the cleanest cut and to prolong the life of the cutting edges, we recommend using a suitable cutting lubricant.
Use this tool for:
- Fabricating diamond-shaped pendants, charms, and earring components.
- Creating custom inlay pieces for metalwork or mixed-media projects.
- Producing uniform blanks for subsequent stamping or enamelling work.
- Cuts four distinct diamond shapes from non-ferrous sheet up to 18 gauge (1.02 mm).
- Includes punch sizes (approx): 29x26mm, 25x22mm, 21x18mm, and 14x14mm.
- Punches and die block are machined from hardened carbon tool steel for clean cuts.
- Compact 76 x 76 mm (3 x 3 inch) die block fits easily on a jeweller's bench.
- Punches are ground sharp on the cutting end and bevelled on the striking end.
