INCRA Guaranteed 45 Degree 7"


This innovative one-piece design uses the most advanced manufacturing methods available to carve a solid 1/4"-thick slab of hardened aluminium into a one-piece, gold-anodised spine that serves as both the central part of the handle and the blade for exceptional accuracy and consistency.

INCRA's new line of Precision Squares and 45°s are the most accurate you will find anywhere. Each INCRA square is guaranteed +/-0.001" from nominal along either side of the blade!

The spine also projects beyond the handle's cheek plates on the inside of the square, producing a support lip that makes it easier for the user to keep the handle flat on the edge of a board. There's even a recess machined into the spine's inside corner to keep the fuzzy corner of a board from affecting your measurement.

Solid AND Beautiful

The hefty construction of the Angles just feels right in the palm of your hand. Incra's trademark gold and red hardened anodized surface is not only durable, but beautiful, and it won't tarnish like brass or rust like steel. Combine this with the 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).

Reliable angle but expensive

I like nice quality reliable tools. It was difficult to justify the expense of this 45 degree ‘mitre square’ but having done that, I’m glad that I bought it. In fact it was in use checking a 45 degree cut I had already made only 10 minutes after delivery and I’m happily surprised at how often I’ve reached for it now that it hangs in my workshop. It is accurate and made to the same sort of standard that you’d expect from Incra. You can buy cheaper but what’s the point of doing that if you can’t totally rely upon the accuracy.

I bought the 7” version and for me, that is as small as I’d want to go. I haven’t handled the 5” model but the space in the 45 degree angle is quite limited if you’re marking with a pencil so I’d guess that the 5” version might be less useful than the 7”.

One of the photos shows the square standing on its side to set a tilted saw bench blade. It clearly does do that but isn’t as stable as the photo indicates...but that’s a small criticism and overall I’d say that if you can afford to spend this sum on a square like this, then I’m sure you’d be happy with this one. I’m happy I bought it and I would buy it again.

Accurate, beautiful.

At some point during most joinery processes it's necessary to test your work against a reference that you trust, be it a square, straight edge or flat surface.
Already owning a 90* Incra I know how good they are and decided to splash-out on the 7" 45*.
Like the 90* it's a beautiful looking tool and there is no arguing with the accuracy .
