The Woodpeckers 18” Precision Woodworking Square combines the size of a carpenter's framing square with the precise construction of a furniture maker's try square. The reinforced beam lets the square stand on its own and provides an accurate edge reference you'll never get with a framing square. It’s the ideal tool to reach for when doing critical layout work on sheet goods and when setting up track saw cutting stations.

What separates Woodpeckers Squares from the rest is its one-piece central core. They mill the core from cast and ground tool plate aluminum (the most stable aluminum made). The central core gives Woodpeckers Precision Woodworking Squares an accuracy and stability not found in competitive tools.

The core is a precisely machined complete square. Woodpeckers’ milling methods, combined with the high-quality material, allow the square to hold the tolerance to ±.0085°…that’s one-thousandth of an inch per 12" of blade length. To this highly accurate core, cheeks are added to make the base thicker. The combination of the one-piece core with the precision-pinned cheeks can’t be matched by squares made with a blade riveted to a separate beam.

The cheeks are narrower than the core by a 1/4", forming a shoulder not found in traditional square designs. The shoulder allows the square to rest on the edge of a board without support. Once you’ve used a Woodpeckers square with the shoulder, you’ll wonder how you ever lived without it.

The hands-free design, the wide stable base for vertical use and the heft and balance of this square combine to make it deadly accurate and a joy to use. It has laser-engraved scales on both sides of the blade to an accuracy of ±.004" total accumulated error over the entire length of the scale.

When the job is done, your square can be stored in a wall-mountable Rack-It™ that keeps it safe, but always in plain sight and ready for the next project.

Woodpeckers takes great pride in the design and manufacturing of this square. So much so that they will repair or replace your Precision Woodworking Square anytime you find it to be out of tolerance. No fine print, no disclaimers. If it’s not square, they’ll make it square or replace it.
