You’ll Never Question the Reliability of Our Model 641 and 851 Squares. Designed for woodworking, our new squares deliver the precision woodworkers demand and offer features not found on other squares. For years and generations to come, these will be tools you can trust every time you reach for them.
Unmatched Precision and Finest Quality Materials. The 6” long 641 and 8” long 851 Square (also available in metric scales) start the manufacturing process as a solid piece of very expensive, extremely stable, cast aluminum tool plate. The plate is then carefully machined in multiple, high RPM passes on our state-of-art CNC equipment. The result is a single-piece blade and handle square. This manufacturing process insures the 641 and 851 Squares are accurate to within .001 inch or less along the full length of the tool.
