Woodpecker Model 641, 150mm Precision Woodworking Square with wall mountable case, 1mm graduations. Made in U.S.A.

The 150mm long Square is machined from a solid piece of extremely stable and durable cast aluminum tool plate using state-of-the-art CNC equipment, resulting in a single-piece blade and handle square.  The quality of the material combined with the state-of-the-art equipment and a meticulous manufacturing process ensure that these Squares are accurate within a tolerance of .001 inches or less along the full length of the tool.

The solid precision square blade is then sandwiched between two pieces of precision-machined aluminum to form the cheeks of the handle.  These two pieces are fastened to the blade to form the handle with 2 stainless steel dowel pins to ensure complete rigidity and perfect alignment. 

The blade of the square is 1/4" thick and the handle is 3/4" thick making it easy to stand the blade upright and effortlessly check the square on your table saw blade, jointer fence, band saw blade, or other machinery set-up operations.  It also makes checking the square on your casework parts a breeze.

There is a small notch milled into the inside corner of the square to allow you to "zero-out" your layout line all the way to the edge of your work.  Both sides of the blade feature easy to read measurement scales laser etched in 1/16th increments.  These squares are built so well and made so exactingly, they come with a lifetime manufacturers guarantee to stay square to within .001" or Woodpeckers will repair or replace it upon return and inspection.

Available in Inch.  Also checkout the Combo Set which includes both the 150mm Square and the 200mm Square.
