  • 1/4-inch solid alloy body and the 3/4-inch thick integrated alloy handle

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. From the Manufacturer INCRA's new line of Precision Squares and 45 degrees 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! Featuring advanced design and fabrication. Our innovative one-piece design uses the most advanced manufacturing methods available to carve 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 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.

  • Accuracy 100%
Size: 7-Inch
If you want accuracy this incra 7" is what you need. Sadly, I was unlucky to received mine with a top corner dmg but it didn't affected at all the accuracy in my opinion.

  • Not exactly as described, but really quite nice
Size: 7-Inch
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. 10/23/2013 - I'm updating this review and increasing my rating from 3 to 4. I use this square every time I'm in the shop and really like it. I've also bought the 45 degree "square" from Incra. I think Incra is a little more interested in making pretty things than they perhaps should be, but as far as I can tell this is an excellent product. I checked it against some machinists blocks at work and found no issues with it. For the price, you are buying more than a cool-looking red and gold assembly of anodized alluminum. ... show more

  • It’s square, would like a slimmer case
Size: 7-Inch
Square functions well as a square. My nit pick would be for the hundred dollars I paid for this beautiful square. Is it takes up too much space in my drawer. For the price your paying should come with a L shaped case that fits it snug. Rather than a generic cardboard box that has copious padding in all directions. ... show more

  • A beautiful & accurate piece of equipment
Size: 5-Inch
What a lovely piece of ACCURATE equipment! I just returned 3 Kinex Measurement squares (see attached picture - not even close to 90 degree), that said they were guaranteed to be 875/0 accurate (something like 4-8 micron accuracy), and boy am I glad I did. Being frustrated with the lack of accuracy, from Kinex, I did a little more research and found Incra's guaranteed square. Just like others, I was debating between this square and the red peckers. Sure, they both might be considered expensive, but if accuracy is your thing.... Today, I aligned my tools with this square, and it really improved my accuracy. Check out the picture of my scrap wood. Perfect 90 degree angle! I recommend Incra's Guaranteed Square over the red peckers... any day of the week. Heck, even the weekend, too. 😁 I really like this square. I like it so much, I bought the 7" version, too. Buy one, you won't regret it!! ## Review Update: 5 to 4 stars ## Compared the Incra 5" & 7" and they seem to be slightly off. Check pictures. Returning\exchanging. Hopefully the replacements are more precise ... show more

  • Typical Incra Product
Size: 7-Inch
A couple of reviewers had issues with this tool. I don't! I own several Incra products and I am very pleased with this square. They (Incra) think things through when they build something. When I first took this tool out of the box I was immediately impressed with the fit and finish as well as the "heft" and the overall feel. (Anyone that uses hand tools knows what I mean.) Like other reviewers, I too like the way it stays put when you lay it on a board. Overall I like the accuracy that Incra products provide. Between my "Original" Incra jig, center finder rule, bend rule, 6" T rule and SE1000 miter gauge my work comes out square and true. I was a little concerned with one reviewer that checked his jointer and found his square wasn't up to the task.I checked the fence on my jointer with the OUTSIDE of the square and found it to be at 90 degrees to the table with a light shining behind it. ( I also used a digital tilt box with the same 90 degree results) I then ran a piece of 8/4 oak through the jointer to get the "face" square to the edge and checked it with the INSIDE of the square and found it to be true. I checked my mitre gauge set at 90 to the blade and found it be true as well. If you are new to Incra products go to their website and look at their products and then search the internet for other reviews and comments. Woodworkers love them! their products are accurate, they stand behind them AND they are made in the USA! The accuracy of this square is more than enough for a low brow woodworker like me. I would recomend this tool or any other Incra product to any woodworker that wants to take his work to a higher level. ... show more

  • Immediate Improvement
Size: 7-Inch
Expensive so I gave value of 4 but this tool immediately showed me how off my other squares were. Noticed it in my first couple of glue ups this morning. Pieces fit together perfect with no trimming like I was having to do before. There might be comparable products for less $$ but I can only speak to this piece.. High quality.. Accurate.. and well made. Very happy with purchase. ... show more
