Rhin-O-Tuff Tornado EX Die Sets

The correct hole count depends on the paper size, pitch, edge placement, and production setup. Both dies may use a closely related coil pattern, but the number of holes and their position across the sheet can affect alignment at the first and last edges. Do not select by hole count without confirming the intended sheet dimensions and current binding supplies. If an existing job is being reproduced, use a successfully bound sample or production specification to identify the required pattern. For a new job, test the paper, covers, coil, and trimming arrangement together. The final holes should have acceptable edge margins, and the coil should pass through without forcing or leaving an awkward unfinished end.

A 2:1 die punches two holes per inch and must be used with 2:1 wire. This pitch supports larger wire diameters and is commonly selected for thicker documents. A 3:1 die punches three holes per inch and works with 3:1 wire, generally used for thinner documents. Tornado options may also differ by round or square hole shape and by the hole count needed for a particular sheet size. Pitch compatibility cannot be corrected during closing, so the wire size and die must be decided before the document is punched. Suitable wire binding supplies by pitch should be selected according to the finished document thickness.

A loose-leaf die is suitable when pages will be placed into ring binders or filing mechanisms rather than permanently bound with coil, comb, or wire. The required filing pattern may use two, four, or another arrangement of holes depending on the binder and document format. It should not be selected merely because the document needs fewer holes. Measure the binder mechanism, confirm the centre-to-centre spacing, and use the corresponding Tornado die. A filing pattern will not work with ordinary coil, wire, or comb spines. Where one production department handles both filing work and permanently bound documents, separate dies allow the Tornado EX to support both processes.

Estimate how often the new binding format will be produced, the required sheet sizes, paper stocks, cover materials, and finishing steps. A new die can reduce outsourcing or remove the need for another punch, but the operation may also need matching spines and finishing equipment. Storage and changeover procedures matter because dies should be kept clean, protected, and clearly labelled by pattern. Staff should know which pitch and supplies belong to each die to prevent entire jobs from being punched incorrectly. The binding supplies needed for the new format should be specified at the same time as the die.
