RUBBER DAM PUNCH AINSWORTH 315220

Used to place holes in rubber dam material to permit the passage of the dam over the crowns of the teeth. The handles are squeezed together and the plunger (punch) creates a hole in the rubber dam material. It is typically designed to create various hole sizes thanks to the cutting disc that rotates through a range of 5 hole sizes, providing the correct opening for the smallest anterior tooth to the largest molar. The punch must always be centered in the cutting hole to achieve a clean cut.
