Can Dangerous Saw Blades Cut Wood?

In this video, we tested a lot of different extremely shaped sawblades! The winner will surprise you. We tested a circle, cross, triangle, pentagon, square, rectangle, crescent, trapezoid, hexagon, star, and some other crazy designs!

Each time this channel uploads is a miracle just because that means they haven't died to one of their ideas yet.

Every one of these blades would have worked if you put the cutting point on the corner.

[jones]

it wouldve been so much better if the geometry of the saw teeth were properly cut out lol

[nnelg]

The problem is the orientation of the teeth on the part of the blade that first contacts the surface, i.e. the corners. As you saw, the teeth on the corners weren't contacting the wood with their cutting edge, so you weren't actually cutting the wood with any of them but the last one, but rather pulverizing them into oblivion.

[mckennaConfig]

The blades the performed the best were because the teeth were closer to the correct geometry at the cutting surface. In most cases, the wood was impacting the back of the teeth which is why they were cutting so poorly. If you do this again, you have to design the teeth to be angled in reference to the center of rotation.

0:21 Why is he starting to run after the cameraman as if he wants to test his weird saw blades on him?

[silygoose]

Some of the blades were flawed because the teeth couldn't cut into the wood and just rubbed on the round side

Bro knew he had to blur the goods. 0:48

Could have gotten your femoral artery closer

[asteroiderer]

The reason why the bar did so well is that, with the few teeth which were actually effective on it, you effectively made a dado blade. You made the equivalent of a circular saw blade that has been cut with two symmetrically placed parallel lines. And the reason why it did better than the circle is with that twist problem of reducing friction like you did with the teeth on the square; since both of them don't have the angled teeth, the circular one was dealing with more friction and less room for chips to escape, while the bar had plenty of air space for chips to escape inbetween hits.

[PrtoPoTaT]

Haha I'm so curious why you started running at us with the saw blades in your hands during the intro

[FisPr]

Your poor neighbors are probably ordering a restraining order

4:36 I'm gonna lose sleep trying to figure out where that Will Smith joke was going.

I imagine other comments have already mentioned this, but there was a triangular circular saw blade advertised on "As Seen On TV" back in the early to mid 90's. It's claim to fame was that it could cut circles and other curves. I bought one and used it exactly once, to cut out a large wood circle to make a Lazy Susan. I created a special table saw jig for this purpose. It worked well, although it scared the heck out of me even though my hands were nowhere near the blade, and it created an enormous pile of sawdust. The teeth were more finely spaced, maybe 15 TPI or thereabouts.

can dangerous sawblades cut wood?
nah just the safety blades

[danielconnelly]

Every saw blade is widest at the teeth, so it cuts a kerf for the rest of the saw to pass-through. Usually the teeth are bent to one side alternating back in forth. Take a nail set or punch and knock every other tooth to one side. Just like .1mm each side will make a big difference

[VlatyleUSMC]

The teeth need to be angled properly for the cut. As long as the blade is balanced, any geometry will work, albeit not as efficiently as a round blade.

[nelsonfields]

the carbide tip found on saw blades are usually a bit wider than the blade to reduce the friction on the body of the blade. If you could have brazed carbide tips on these they would of worked much better.

Now you have to use real saw blades but removing shapes of it, we need to know how much you have to remove for it to stop being useful.
