Bora 530416 QuickCut Circular Saw Guide with Rail & Angle Assist – All-in-One Woodworking Tool, 16" Durable Aluminum, (35.5cm) Guide Rail

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

THIS IS A NICE ACCESSORY THAT HAS A TALLER, LONGER, MORE SUBSTANTIAL TOOL GUIDE FENCE THAN A 7" OR 12" SPEED SQUARE WHICH U CAN GUIDE UR SAW W/IN AT LEAST TWO OF THE ANGLES. THE THING W/THIS IS I DON'T SEE IT LASTING IN THE FIELD. THE BODY OF THE SQUARE IS SOMEWHAT FLIMSY & THIN. THE PLASTIC RAILS THE ALUMINUM FENCE RIDES IN ARE SUBJECT TO GAULING (FRICTIONAL PEELING). THE 22.5° & 60° ANGLES ARE RARELY USED I FRAMING, IF AT ALL, THEY'RE USED IN INTERIOR TRIM MILLWORK & DONE ON A COMPOUND MITER SAW & NOT FREEHAND. FINISH CARPENTER'S DON'T NECESSARILY USE CIRCULAR SAWS THEY RIP W/A TABLE SAW & CUT MITRES & COMPOUND MITRES ON THE AFOREMENTIONED COMPOUND MITER SAW OR SLIDING COMPOUND MITER SAW.

As described

I thought it would be nice easier and more accurate to use. I was using a track saw for accurate cuts and wanted something smaller for small cuts. The product is confusing and will move on you, ruining the accuracy. Flimsy and cheap. It had some kind of self clamping that might have made it worth it. Now I just use it as a straight edge

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

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.

A speed square will guide a 90 or 45 degree cut as well or better than this tool, so the reason to purchase it is for 22.5 and 60 degree cuts. I bought it for the 22.5 degree cut, the angle for rafters in a 5:12 roof pitch. But the tool is not very good for that acute angle because of the way it is designed. When you hold the plastic ledge of the orange handle flush against the edge of a 2x board, the metal straight-edge doesn't make contact with the face of the board but hovers above it about 4mm. As a result of this lack of contact, the guide can tip forward and rotate on the rounded edge of the 2x board, loosing its purchase on the edge of the board. The lip on the metal ruler needs to be 4mm longer so it makes contact with the board, to keep the guide from rotating on the board edge. See photo. But with a clamp of the proper size and strength, the Bora guide should work OK even for that acute angle. Several of my clamps didn't quite fit, inlcuding the very strong Jorgensen 6-inch E-Z Hold. A small Irwin Quick-Grip did fit but it's not really strong enough to keep the Bora guide firmly in place when using a heavy worm-drive saw. Be prepared to find a suitable clamp if you intend to use the Bora guide at 22.5 degrees.

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...

Muy práctica y util para quienes no tenemos guias mas caras para sierras y caladoras de mano. Tiene 4 ángulos básicos. LA regla de aluminio muy buena calidad y el plástico tambien. Me ha funcionado muy bien hasta el momento para cortes rápidos.

Super

Works well and solid build. Nice tool to have.

Excellent bit of kit very handy for those quick jobs.
