Woodpeckers CDSQ-BL06-20 Square Blade, For: In-Dexable Squares

The combination square was invented in 1878 and has been copied countless times over the last 140+ years, Woodpeckers product development team wanted more than just a "me too" product. They built features into our in-Dexable combination squares you won't find in any other combination square at any price. Features like laser accurate scribing guides, positive indexing at every full inch, a sliding head support and accurate, laser-engraved scales. To round the system there's a double square head, XL versions of the combination head and double square head and we've recently added a new centering head and a new protractor head, with the same precise full inch indexing feature.
