Bora QuickCut Circular Saw Guide with Angle Assist, 16in

This has become my go-to circular saw guide for quick cross cuts. No setup time at all and very safe. Lightweight but solid build quality. The straight edge is also good for drawing lines. And the ruler is very handy to quickly doublecheck short lengths without having to pull out the tape measure. I just leave it hanging on a peg for a quick grab and cut. Easy to wipe/shake off dust from the cut. A very practical invention.

Awesome, been using it for years

I built a large trellis with the Bora tool plus a 20V Porter Cable hand saw. It is extremely helpful and made the project fun and accurate. Love this tool. You must use it with caution, and it is possible to run your circular saw blade onto the tool if you are not careful in your stroke.

The main body is polymer. The straight edge is aluminum. The aluminum edge does not slide easily within the body. I guess this is a good trait. The primary caveat to this tool is that it's difficult to hold to the board and hold the board too, while trying to use the saw. The other issue is that the body (plastic part) has rubber inserts in the edges to help prevent the unit from sliding on the edge of the wood while its being held in place. That is a nice idea. However, in trying to hold it in place, and the board, and use the saw, I discovered that these rubber inserts are easily compressed. Your 90* cut line ends up not being 90*. I find it difficult to use on anything other than a 2x4. YMMV

So I really like this device. Here are my suggestions for improvement that would make it even better. First, the edges where the device meets the cutting surface should be thicker so it is easier to mate to the edge especially if there is some kind of bevel on the board like for trim material. Second, the instructions should be on a durable plastic material that is thick enough to be easily kept. You are going to want to refer to it if you are a rookie like me and want to figure out the way to insert the metal ruler portion into the plastic cutting angle guide. There are several ways to insert it to get the different desired angles of cut and if you do not do it often it takes multiple attempts to get it right.

This is so hard to use.

As described

I read the mixed reviews and decided to try it anyway. Unfortunately, the negative reviews were right. The concept is good, but the execution is poor. The extruded aluminum track is nice, so I give that 5 stars. But the plastic handle is junk, so I give that 1 star. The fit of the plastic handle into the channels of the aluminum track is poor, making the angles inaccurate and the track difficult to adjust. Both the 90 and 45 degree angles were off by half a degree. If I wanted accuracy that bad, I could make my cuts freehand. I do like the aluminum track, so I'm going to keep that and build my own handle from scrap plywood and some aluminum angle I have lying around. But this is the kind of thing that drives me crazy as a mechanical engineer. It wouldn't have been that hard or expensive to make a better, more accurate handle. Now I have to make one myself with free scraps from my shop, and it will work better than the crappy Chinese plastic I just paid for.

La poignée est un peu légère au niveau de la qualité du plastique et lorsqu'on modifie la position de celle-ci sur un autre bord, les rainures ne s'ajustent pas correctement. A voir à l'usage...

Buena calidad y facil uso de esta herramienta para carpinteros

Sehr zufrieden sehr Praktisch!

Excellent to use with skill saw. Makes cutting carcassing and joists so easy.

Works as described, helps make quick cuts. I used it to make 90 and 45 deg cuts so far and it really helped me make fairly accurate cuts - good enough for diy deck build job.
