Upgraded 340mm Track Saw Square Right Angle Circular Saw Guide Rail Angle Stop Accessories Compatible with Festool and Makita Guide Rail (Red)

I didn't expect much for the price, but figured for the price if it would allow me to quickly do rough parking lot breakdowns of materials they won't cut at the big box (MDF/Melamine, etc.) it'd be worth it. First, it does indeed work with my M18 track (see pictures) and locks in very securely, though I wish the clamping pressure were adjustable as it feels very tight almost like something will bend. Second, I did a quick check with my Veritas square (accurate to 0.001 per inch) and it was surprisingly square (see pictures). I'll update the review after making cuts if something unexpected happens, but overall this is a decent product.

Works great with my Milwaukee track saw and track. Square and stays square. Seems well made for the price, and is adequately sized even for my longer track. It actually made me realize that two of my shop squares were not perfectly square. Over an 8-ft distance it looked like it wasn't lining up properly to my marks when in actuality the squares that I used to make those marks were not square. Two of my higher quality squares match this perfectly

I got this for my Wen track saw, and sadly it is not good. It fits the track fine, but it is not square! And there is no adjustment to fix it to square! I attached it to my track, and using a framing square, it was out by 1/16th at 14" from the guide. In case this was error in the square, I got another one it was the same. Finally, I made a test cut on 4ft plywood and the cut was off my nearly a 1/4 of an inch!! I checked the square for any way to adjust it, and there is no way. I tried some painters tape on the show that goes into the track, so it would be held askew, but that was not sufficient to correct it. I am refunding mine and now I have to wait for a better one to be delivered. Project delayed!!

This is just a first impression. Conclusion: Excellent value, very accurate, and perfectly usable with some care (like all tools, really). See below for things to look out for. Comments: Before attaching the square and before cutting, it's very important to make sure there is no debris anywhere two surfaces meet, like between the track and the square, and between the square and the reference edge of the work piece. It's a very good idea to run the saw with a vacuum. There may be a lot of variance in accuracy from unit to unit. The all-important rail is attached to the body with screws. All the name brand models are machined out of a single piece of aluminum. So, test yours when you get it. I have no idea how it will stand up to use. The clips or the rail that lines up against the track (not the T-slot rail) would be be the first to fail, and those are the most important components. Pros: My unit is dead accurate. I ran the 5-cut test and the error is within measurement limits (say, less than .2mm) over about a 50 cm square. (I didn't have a bigger scrap I could use.) It looks nice. The main body machining looks very good. Cons: It's a little fussy to use. The most important thing to look out for is to make sure the body of the square is pushed up against the track before clipping it on. Otherwise it may not be snug against the track, possibly even damaging the track. The hinge pins on the clip hooks are loose and can stick out and prevent the clip handles from being pushed down. The cutouts on the body for clamps are too small. The (laser-cut?) anti-tip tab has sharp edges and might scratch the work. It has already scratched the anodization on my square and possibly cut my finger (well something cut my finger). I'll probably clean it up with a file or abrasive stick. It's not at all a critical component so I'm not worried about it.

Perfectly 90 degrees. This came fully assembled and ready to use out of the box. The connection to my Milwaukee track guide is rock solid once the clamps are engaged. I should have got one of these a long time ago, this is significantly faster, easier, and more accurate than me using my triangle square. If you’re considering this or a much more expensive guide square, don’t waste your money. This does everything I need it to do, at a reasonable price. I highly recommend this square!

This was square from the package and works well with the Festool track. For a discount imported product the fit and finish is pretty good and it’s been a useful tool at a good price.

It works, and is decent quality. However the clasps are really cheap. Unlike the more expensive products like this, it does not have any plastic coating on the clasps so I am always afraid they are going to damage my expensive track saw rail. It does have a long rail to go in the underside of the rail - but this is both good and bad - more stable but also it jams up with the under rail clamps that share that rail. Its a good price though, so I keep it around to use once in a while.

Got this for my husband as a gift and he said it is exactly what he wanted. He was so happy with it. It will improve the accuracy of the work he produces.

Have been using the DDWT 340mm track saw square for a while now and I am very happy with the results it's easy to attach and remove meaning that it simple to change from my 700mm track to the 1400mm track for one longer cuts, I normally check for square at the beginning of the day and it's always bang on.

Out of square .5mm over 150mm (6inch). Long cuts will be way off. Also the clamps damaged my $300 festool track. it puts small dents in the track every time you use it so will destroy your track more and more with each use.
