Euro Machinist Square 100mm X 70mm (4 Inch)

Part # 135.068 4 In Stock Weight -- lb -- g
Current price $29.00

A machinist square is the metalworker's equivalent of a woodworker's try square. The term square refers to the tool's primary use: measuring the accuracy of a right angle (90 degrees). To try a surface is to check its straightness or correspondence to an adjoined surface. This professional-grade machinist square is machined from a single piece of bar stock (billet) — unlike less expensive alternatives welded together from two separate pieces of material — delivering superior rigidity and long-term accuracy.

A small notch has been added to the inside corner to prevent small particles from accumulating and affecting the square's reading, a practical detail that makes a meaningful difference in precision work. Made from stainless steel (INOX) and manufactured in Bulgaria, this square meets back accuracy in accordance with DIN 875/II (DIN 875/2) standards. A graduated scale runs along the taller foot — 100mm on the outside and 75mm on the inside — adding versatile measuring capability directly to the tool.
