Square Head Protractor

Needed something for my son for home for his math homework. We had one from a certain company with a mustache, and it was an utter piece of junk, so we wanted something more useful, not plastic.This looked like it would work, and was metal. So we gave it a try.Love that unlike the others we were using, the standard arched plastic ones, it's easy to draw the angle with a single placement of the protractor and a single movement of the pencil.The thumb screw tightens for people who need that to hold it steady while using it.I was worried the size would be a bit awkward, but it's proven to not be the case.Can't beat it for the price, best protractor I've ever had.

Great product, I didn’t expect such high quality for the very reasonable cost of the product (and it’s stainless steel too!). I’m sure it’s great for many uses, but if you need something to measure the exact degree of deflection for your Flaps, Ailerons, Horiz. Elevator, and Rudder, it’s very accurate and easy to read even with my 56 year old eyes. It’s not made out of cheap thin stainless either, I was very surprised at the thickness and quality. Great buy imo.

I ordered one of these to keep around the shop and the first one arrived with an inaccurate scale off by about 1 degree, reading 89 degrees when checked against a verified-accurate machinist's square. MAKE SURE YOU CHECK YOUR GAUGE AGAINST A MACHINIST SQUARE BEFORE USING IT FOR ANYTHING. Obviously when you're using this to transfer angles for replication or to create the inverse of an angle, where you won't be actually measuring the angle and are just using it as a transfer tool, then this becomes a non-issue but when using it to actually measure an angle it's frustrating. Needless to say, that unit gets one star. However I decided to give the manufacturer/Amazon another shot before leaving my review, and I contacted Amazon about the issue and a replacement was sent immediately, arriving 2 days later. They didn't request the original back so that one can still be used for just transferring angles, and I handed it off to a co-worker with the warning about the scale so he can use it for a transfer tool.The replacement is accurate! Note that this isn't a "precision scale," as the marking for reading the angle is itself is about 0.5mm wide and that presents wiggle-room in the potential for mis-reading the scale very slightly, but it gets you in the ballpark, and on the replacement it actually lands on 90 when measured against a machinist's square.It's a solid little tool, and very simple. Provided that the scale is marked accurately, there's really not much that can go wrong with this tool aside from being crushed/bent/destroyed through negligence or accident. It is low-tech and perfect for work where "good enough" certainly is; I'd advise against using it to design a space shuttle or something where the difference between 45 and 44 degrees might be a life-or-death situation, though I don't suspect folks doing such things are looking to pinch pennies on angle gauges. It was a bummer that the first one's scale wasn't precise but given how quickly and easily the issue was rectified with absolutely no fuss, I don't feel I can exactly fault the item for that sour first experience. I'd say that if you're in the market for an item like this and trying to keep the cost down, go ahead and take a shot if you're buying from a company that's easy-breezy with returns/replacements: in my experience, if you catch any accuracy issues quickly Amazon and/or General Tools will take good care of you.

came as described

I do a lot of work with small wooden parts layout. Scribing lines in 1/4" and 1/8" thick stock. Typical squares just do not work well for these small thicknesses. This device quickly became the most used layout tool in my shop when doing this type of small parts work. Extremely accurate and easy to read scale. Provides for fast layout to square which I use the most, but also very easy to re-set to any desired angle. Thumb screw loosen, set and tighten in seconds.Great tool, and outstanding value for the money.

I use a Mitutoyo protractor which is almost identical but much more expensive. I wanted a second one for another area of my shop. I was wary about the General Tools version but it appears to be as precise as the Mitutoyo. The “fit and finish” is as expected with the much cheaper tool but it functions well. (It has the same precise indicator method missing from some of the cheaper machinist’s protractors.

I've used this tool now for over a month. I love it. It's a perfect size for smaller projects. Very well made, and accurate. There are over 150 types of Stainless, from experience this Protractor appears to be of the stronger steels and very durable. The curling thumb knob takes a bit of effort to crank down but nothing which hinders quick work.Besides using it for a job it also comes in very handy to align the bevel and angle of the saw blade. A handy tool I wished I bought it ages ago. I don't know how I got along without it. A tool which is a must in every workshop.

The gauge is fine for 90% of uses, but trying to dial into a specific angle is virtually impossible due to the width of the cursor and the protractor marks. It'd also be nice for the entire assembly to be thicker so it's easier to reference the straight edges, as right now it can be a bit of a balancing act.The locking nut is also pretty loose. From the factory, the washer that aides in the locking was also installed incorrectly (the notch was rotated 90 degrees in the wrong way) which prevented it from locking at all - even after fixing that, it only gets a little tight, which means it only takes a small amount of force to knock it off the angle you set it at. My recommendation if you get this: use this to find an angle and use it to set a T-bevel or another angle gauge, and reference the rest of your measurements off of that. This isn't reliable or accurate enough to be the primary reference in a project.

Well built and very accurate for my woodworking needs
