Euro Machinist Square 50mm X 40mm (1-5/8 Inch)

A machinist square is the metalworker's equivalent of a woodworker's try square. The term square refers to the tool's primary function: measuring the accuracy of a right angle (90 degrees). To try a surface is to check its straightness or its correspondence to an adjoining surface. This precision instrument is an essential reference tool for jewelers, metalsmiths, and machinists who demand accuracy at the bench.

This small machinist square is machined from a single piece of stainless steel (INOX) bar stock — known as billet machining — rather than being welded together from two separate pieces of material, as is common with less expensive alternatives. The one-piece construction eliminates the joint inconsistencies that can compromise accuracy. A small notch has been added to the inside corner to prevent fine particles from accumulating and affecting the square's reading.

The square features a graduated scale along both sides of its height: 50mm on the outside and 25mm on the inside. Back accuracy conforms to DIN 875/II (DIN 875/2) standards.

Features

• Machined from a single piece of stainless steel (INOX) bar stock — no welds, no joints
• Inside corner notch prevents particle buildup that could skew readings
• Graduated scale on both sides: 50mm (outside) and 25mm (inside)
• Back accuracy in accordance with DIN 875/II (DIN 875/2) standards
• Compact size ideal for bench and detail work

Specifications

Notes

This square is manufactured in Bulgaria and machined from solid bar stock. This distinguishes it from lower-cost India-made squares that are welded from two pieces of material. DIN 875/II is a recognized German standard for precision squares that specifies permissible tolerances for back accuracy.
