Woodpeckers 641/851 Precision Square Set - Metric

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.

A Dream to Use. These squares are stout, yet light weight and offer superb balance. The 641 Square is small enough to tuck neatly into your shop apron. The larger 851 Square is perfect for bench use.

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.

Once we have a perfect square we add two pieces of precision-machined aluminum to form the cheeks of the handle. These cheeks are fitted to the handle with two stainless steel dowel pins that ensure bulletproof rigidity and perfect alignment when pressed into their precision-machined holes. This kind of strength and accuracy simply cannot be matched by squares made using separate blade and handle parts or punched-out on a stamping press.

We even mill a notch at the inside corner of the square so you can zero-out your layout line all the way to the edge of your work.åÊ Easy to read measurement scales are laser etched in 1/16th increments on both sides of the blade.
