Workshop accuracy begins with a benchmark straight edge as a surface reference. These Canadian-made precision steel straight edges are ground flat over the entire length on both edges, the 610(24") length to within 0.025mm and the 915mm(36") length to within 0.038mm. All have been stress relieved to remain true under temperature variation. Useful for checking whether surfaces are flat or straight, they are 38mm wide and easily stand on edge unsupported, leaving both hands free for precise measurement or tool adjustment. All have hang holes, allowing storage on a nail or hook.
610mm(24") Steel Straight Edge
An invaluable aid for machine set-up, the 610mm straight edge is a good size for setting up stationary machines such as planers and jointers. At slightly more than 1kg, it weighs enough to stay in place while you make adjustments. 6.3mm1/4" thick.
