Precision Steel Straight Edges by IGAGING
Precision at a great price!
Now you can adjust your tools properly and accurately for a fraction of the cost. These straight edges are great for checking surfaces for flatness and straightness or for checking two separate parts for alignment. At 1-7/16" wide and 3/16" thick, they are extremely durable and straight (0.0005" per inch). The bevel "knife edge" makes it easy to use and is marked machinist's style in standard decimal inches while the opposite edge is square and perfectly parallel.
