Benchmark Sets of 5R Machinist Rules with 1/10, 1/100, 1/32 and 1/64 Markings

These rules are made from Japanese rust-resistant stainless steel that has been tempered, creating a measuring tool that can flex if needed but will snap back straight. The edges and ends have been ground parallel, straight, smooth, and square. Graduations are produced via a photoengraving process, creating very consistent and accurate markings with uniform line widths. Once etched, graduations are black-filled for easy readability. Graduations are etched and not printed, so they will not wear off with prolonged use. Graduations conform to strict international EEC 1 Accuracy Standards, i.e. +/- 0.2 mm at 20 Degrees C for 1000 mm Rule. 5R graduation marks feature quick-reading 32nds and 64ths on one side and 10ths and 100ths on the reverse side. The finish is brushed stainless steel. Each rule comes in a vinyl storage pouch.

These are well-made rules and will provide years of reliable service in any shop, studio, clinic, lab, classroom, or home environment.
