The Incra's Guaranteed Square 5-Inch Precision Square features an accurate, advanced design and fabrication, and carves out a single monolithic blade from a solid slab of hardened aluminum. This means you won't see the alignment errors that can happen when a separate blade is manually assembled to a separate handle, as in the more common two-piece design. Solid, rugged and beautiful, the hefty construction of the 1/4-inch solid alloy body and the 3/4-inch thick integrated alloy handle just feels right in the palm of your hand. Unlike conventional two-piece designs, the layout angle of this rigid, one-piece body won't get bent out of shape when you drop it. The trademark gold and red hardened anodized surface is not only durable, but beautiful and it won't tarnish like brass.
These 45- and 90-degree squares are so precise that they come with a certificate of accuracy that guarantees each one has an angular maximum deviation from nominal of less than 0.001 inches at any point along the full length of the blade. Set cutting tools to the perfect angle, while a support lip holds the tool on the edge of the work piece for marking and layout. Combine this with modern, functional styling and you've got a tool that is worthy of the most prominent location in your display cabinet.
