Akiles Die Sets

Round hole dies are the standard choice and work with the widest range of coil diameters and colors, while oval hole dies are built for a specific coil profile that some heavier-gauge or specialty coils require. Using the wrong hole shape for your coil supply typically results in the coil sitting loosely rather than gripping the punched holes securely. Checking your coil supplier's specifications for which hole shape their product is designed for, before selecting a die, prevents this mismatch.

Yes, that's the core advantage of Akiles' modular die system — a single punch can handle multiple binding styles by swapping in the appropriate die set, rather than requiring a separate dedicated machine for each style. Changing dies does take a few minutes of downtime each time, so an office regularly running high volumes of more than one binding style may still benefit from keeping a die pre-installed and switching only when the job mix changes. For occasional mixed use, one punch with a shelf of die sets covers the need without the cost of multiple machines. For the punches these dies are built for, Akiles binding machines covers the full equipment lineup.

FlexiPunch dies are rated to punch up to 20 sheets of standard bond paper per stroke, which suits lighter office or small print shop volume. VersaMac dies step up significantly, rated for around 55 sheets per stroke, which matters for high-volume production environments punching large batches throughout the day. If your typical stack size regularly approaches or exceeds 20 sheets, the VersaMac platform's higher capacity prevents the multiple-pass punching that a FlexiPunch would require for the same job.

Disengageable dies let you turn off selected punch pins so the pattern stops cleanly at the edge of a shorter or narrower sheet, which matters if you regularly bind half-size documents, custom covers, or calendars that don't span the full standard width. Without that feature, punching an undersized sheet can produce partial or torn holes near the edge. If your binding work is consistently standard full-size sheets, a fixed-pin die works fine, but for mixed sizes or specialty formats, checking that a die offers disengageable pins before ordering avoids that specific problem. Reviewing the Akiles modular punches lineup helps confirm which machines support this feature alongside their compatible dies.
