Tools and Hardware Reviews of Incra GSQR7 Guaranteed Square 7-Inch Precision Square
Customer Review: Not as described
Summary: 3 Stars
Most people who buy a precision square do not have any means of checking to see if it is precise as the manufacturer claims. So, we have to rely on the reputation of the manufacturer and on the recommendations and critiques of others. Before I ordered the GSQR7, I read the reviews here on Amazon. I was persuaded that it was an excellent product (although I had not previously heard of Incra). So, I ordered it.
It arrived very quickly via the free shipping.
Right out of the box I was a little surprised to find scratches on the square. I concluded that these were probably the places where the electrodes were attached during the anodizing. The next realization was that, despite the prominent claim of the manufacturer that this is a "one piece design", it certainly is not. I counted 12 pieces in all (including 4 bolts, 4 nuts and a decal) and I can't imagine anybody honestly describing it as having fewer than 3 pieces - the main "L", and the two red handle pieces. Certainly this would be less expensive to manufacture than a one piece design, but it's not what I thought I was buying.
I also noted that there is a threaded hole in the blade of mine, which is not shown in any of the photos on the product package nor in the photos shown here on Amazon.
The manufacturer has made two claims
1) It's a one piece design.
2) The blade is accurate to within 1/1000 of an inch throughout.
The first claim is clearly untrue. I don't have any easy way to verify the 2nd claim.
The product did not come with any documentation other than a little card which says "Certificate of Accuracy : Incra guarantees the accuracy of this precision instrument to conform to all manufacturer's specifications. Angular accuracy is guaranteed to be less than 0.001" maximum deviation from nominal at any point along the full length of the blade."
However, no "manufacturer's specifications" were supplied with the product. Also, it is interesting that they specify that only the "blade" is accurate, not the handle - and yet the handle is flush with the blade on the lower side (so that inaccuracy of the handle will affect the results in actual use) and one illustration on the box demonstrates the product being used in a configuration which relies on the accuracy of both the upper surface of the handle and the blade.
So, I'm disappointed. Perhaps everything is just great. Perhaps the handle is just as accurate as the blade. Perhaps the entire unit is square on every surface to the specified 0.001". I simply don't know.
If Incra is going to make a precision instrument, then they need to make precise statements about it.
Description of Incra GSQR7 Guaranteed Square 7-Inch Precision Square
Our Name is Our Promise
INCRA?s new line of Precision Squares and 45°s are the most accurate you will find anywhere. We?re so proud of their quality, that Guaranteed is more than just our promise ? it?s our name!
Advanced Design and Fabrication
Our innovative one-piece design uses the most advanced manufacturing methods available to carve out a single, monolithic blade/handle body 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 Squares just feels right in the palm of your hand. And unlike conventional two?piece designs, the layout angle of our rigid, one?piece body won?t get ?bent out of shape? when you drop it! Our trademark gold and red hardened anodized surface is not only durable, but beautiful, and it won?t tarnish like brass. Combine this with our modern, functional styling and you?ve got a tool that is worthy of the most prominent location in your display cabinet (when you?re not using it, of course).

The Incra's Guaranteed Square 7-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.
