Incra GSQR5 Guaranteed Square 5-Inch Precision Square

Amazon.com Product Description

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.

5.0 out of 5 stars A square is not always square!, October 8, 2003

I once thought that when you bought a square and took it home, it was square. I just got this square today, and I am surprised with its quality and accuracy. I used it to check carpenter's squares, tri-squares, carpenter's speed squares and a precision Starrett branded machinest's square. Each was off up to .010" except the Starrett, which came in a close second this one. Not bad for the Starrett, since it is over 30 years old and has been dropped many times on a concrete floor. The INCRA is better than the Starrett, since the Starrett is rusted and pitted from years of sitting around in the garage shop.

I know that this is one of the best squares I've ever own and will own. My next purchase will the one with the 45 degree angle.

4.0 out of 5 stars Great Tool- decent price, December 11, 2003

I have owned this square for almost a year now, and I find myself using it more and more with each passing project. It, along with most other Taylor Design Group products, is well thought out and has superb machining. I took this tool to work and put it on a surface plate, and it is indeed accurate inside and outside to within .002 along the length of the blade. The part I truly appreciate is that it is as accurate using the inside 90 degree as it is using the outside 90 degree ( or 270 degree, however you look at it :). I routinely use this square to set up all my stationary equipment. To me a square is all about trust. I use this square to set up a tool, then put it away and let the tool do it's job. I own a Delta Beisemeyer for exactly the same reason.

The only draw back to this tool is the price. In the end, its just a piece of aluminum, anodized and all shiny, and it probably cost 8 bucks to make. I feel a lower price would be more appropriate, but in this case you certainly get what you pay for.

You do indeed get what you paid for. It seems to be dead-on as my wood joints come out tight. The lip works great for marking boards, and its perfect for tuning tools. Incra offers a lifetime accuracy guarantee on their website, and even claims ordinary drops can't affect the angle. And I drop alot of tools.
