This all steel 2 Inch Engineer Square is handy for setting up table saw blades, jointer fences, and other machine tools where accuracy is a must. It is also superb for marking out wooden joints or checking cut stock. All surfaces and edges are ground for straightness and parallelism and are accurate on both inside and outside edges (not always the case with wooden body squares). No graduations appear on the blades. Ships in an attractive retail type protective package.
