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.

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.

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

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.

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!!
