Ainsworth Rubber Dam Punch with Rotating Selection Wheel

Manufactured from high-tensile, medical-grade stainless steel, this instrument offers exceptional cutting edge longevity, rust resistance, and total durability under repeated autoclave sterilization cycles. The functional architecture features a heavy-duty, rotating table wheel containing 4 to 5 sharp, multi-sized punch holes ranging from small (for mandibular incisors) to large (for molars). This wheel aligns perfectly with a hardened stainless steel conical punch pin, ensuring crisp, concentric cuts that eliminate microscopic ragged edges—the primary cause of sheet tearing during intraoral stretching.
