NES-3375

Some instruments earn a second variant not because the first fell short, but because different hands and different practices simply want options. The NES-3375 offers an alternate configuration of the classic Ainsworth punch, giving practitioners a slightly different build within the same trusted pattern family used to perforate rubber dam material with precision.
Punch instruments live a demanding life on the clinical tray. They’re picked up at the very start of nearly every isolation procedure, cycled through sterilization constantly, and expected to deliver the same clean, consistent hole size year after year without drifting out of calibration. Having a second Ainsworth-pattern option available gives practices flexibility, whether that means a matched backup instrument, a preferred handle weight, or simply redundancy so one punch can stay in active rotation while its counterpart is being sterilized.
The rotating punch wheel at the heart of this design remains the defining feature: a graduated set of hole sizes accessible from a single instrument, letting practitioners move confidently from a narrow anterior perforation to a wider molar opening without reaching for a different tool. That adaptability is precisely why the Ainsworth pattern has remained a mainstay of rubber dam technique for so long.
Among the maxillofacial surgery instruments supporting isolation work, having two Ainsworth punches on hand, rather than relying on a single instrument, is a small operational choice that pays off during busy clinical days.
Built from stainless steel, this punch is fully autoclavable and designed to hold its calibrated hole sizes accurately through years of repeated clinical use.
