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.

Common questions at the bench

What metal and thickness can it cut?
Only the non-ferrous sheet metal this product's description names, and no thicker than any gauge or thickness it gives. Do not cut steel or any other ferrous metal: sheet that is harder or thicker than the cutter is made for can chip or blunt the punches and the die.
How do I cut a clean blank?
Anneal (soften) the sheet and put a little cutting lubricant on the punch. Stand the die block on a solid, flat surface, set the sheet in it and seat the punch with its cutting end to the metal. Strike the top of the punch squarely and firmly, with the hammer or mallet this product's description suggests if it names one; one firm, square blow gives a cleaner edge than several light or glancing ones.
Will the blank need finishing?
Check each blank. Smooth any burr or sharp edge with a file or fine abrasive paper before the piece is worn or finished, and if a blank has bowed slightly in the cut, flatten it with a mallet on a bench block.
How should I look after it?
Use it only on the sheet it is made for. Wipe the punches and die block clean after use, oil them lightly and store them dry, with the cutting edges kept from knocking against other tools. If a punch sticks, tap it back out straight rather than levering or twisting it.
