The Woodpeckers Saddle T-Squares are meticulously crafted from a single block of aircraft-grade aluminum using state-of-the-art CNC milling technology. Every edge is chamfered, providing comfort during use and an easy grip. Even the small pencil holes have beveled edges to guide your pencil tip accurately. These T-squares simplify perpendicular layout tasks, allowing you to mark square lines on adjacent surfaces simultaneously, enhancing both speed and accuracy. The 3/4-inch deep reference edge aligns perfectly with the scale edge, making layout work efficient and precise. Whether you choose the inch or metric versions, Woodpeckers Saddle T-Squares are essential tools for any woodworking project.
