The most unique feature of the DelVe Squares is easy to overlook, but invaluable once you’ve found it. One side of the base is 1/4" from the blade and the other is 3/8". Mark from the 1/4" side on both edges of 3/4" stock and you’ve just laid out a perfectly centered mortise or tenon. Use the 3/8" side to locate center of 3/4" stock for joinery lay out or hardware installation. The 3/8" side also makes it simple to mark the face and edge of your stock at the same time at exactly the same point. 

With a Delve Square in your pocket, you always have the most commonly needed set-up blocks at your fingertips.  The blade is 1/8" thick and the base is 3/4" wide. Steps are milled into the base at 1/4", 3/8" and 1/2".  Use whichever section you need for machinery set-up, joinery lay-out or other referencing chores.  

Scales on the blades are engraved to an accuracy of ±0.004" total accumulated error. To make accurate layout even easier, there are scribing guides milled every eighth-inch along the blade. Just drop the tip of your pencil in the right hole and slide the base along the edge of your stock for perfectly parallel lines at the precise measurement you choose. To lay out angles, the hypotenuse is engraved in 1° increments with 22-1/2° and 67-1/2° markings added for octagonal lay out. 

Need a hole centered on 3/4" stock? No problem, there’s a hole milled 3/8" from the inside edge of the base and perfectly sized to work with self-centering drill bits.  

Oh, and did I mention that on top of all these nifty design features, the 90° and 45° angles are machined and inspected to Woodpeckers market-leading standards? 

Each DelVe Square comes complete with a wall-mountable Rack-It™ so your square is always protected but within easy reach. 

For years the DelVe Squares were among our most popular and most frequently requested OneTIME Tools®. Now they’re joined our family of always available precision layout tools. Like all Woodpeckers tools, the Stainless Steel DelVe Squares are precisely machined and carefully inspected in our Strongsville, Ohio, manufacturing facility (just south of Cleveland).

Q: What is the difference between the Aluminum and Stainless Steel squares besides material?

A: The biggest difference besides the material the squares are made out of is the marking holes that are milled into the stainless steel squares that are not milled in the aluminum versions.  These holes allow for marking layout lines for projects. The Stainless Steel Square blade is approximately 1/16” in thickness where the Aluminum blade is approximately ⅛”.  The thinner blade and the marking holes along the blade of the Stainless Steel Square allows for it to be better used for lay out lines.  The thicker blade of the Aluminum Square is better suited for making sure work pieces are perpendicular to each other.

Q:  How accurate are your squares compared to others on the market?

A: Our squares are milled and inspected to be within tolerances of .00 1” per foot or .0085°.
