The Crescent Nicholson pillar files are Swiss pattern files with cut grades ranging from 00 - 4. These files are manufactured to provide more precise measurements compared to American pattern files. Pillar files are rectangular in shape and feature a double-cut design on two sides. They have safe edges and are tapered in thickness. While similar in shape to hand files, they are only two-thirds as wide. Swiss-pattern files are engineered to adhere to more precise dimensional tolerances compared to their American-pattern counterparts, ensuring superior accuracy and performance Rectangular geometric configuration Perform a double-cut exclusively on two sides Safe edges #2 cut flat pillar file - engineered with precision-ground safe edges for enhanced user safety and optimal material removal efficiency Exhibiting a progressive reduction in cross-sectional thickness
