trion and down cut blades

[duburban]

Why does my trion buck like a horse when i'm using downcut blades? Tried a brand new one, better but still bucked. Went to an upcut and the problem went away. Are downs prone to this?

Not sure  but the blade would be pushing  the saw up on the cut stroke direction. I used a down cut a long time ago. I don't remember if it tended to cause this or not?

My experience with those type of blades on my old bosch saw was just like yours.  I don't use them any more with the Festool Carvex.  The splinter guard eliminated the need for me.

I use the downcuts nearly all the time on the trion. If you adjust the angle of cut it should help. You can use them to cut just as well as normal blades just needs setting right and dont rush the cut or it will be bucking bronko time again.

Also don't use the orbital setting
Put the switch to O

BTW I don't use those blades anymore

i agree with all your comments. turn orbital off, and cut slow is the only way to use them. Glad to know that my trion is probably ok.

can you further describe "angle of cut" ?

Are downs prone to this?

Yes, they are.
The direction of cut is pushing the tool/motor AWAY from the work, rather than pulling itself into stability.
Turn the orbital action off, go slowly, and add extra force to the head of the tool.

There are times when they are the only option, but they take a lot of extra care.

When i started using them I thought that they were the bees knees. Now I can't get through a day with one.

Must admit I don't use them since discovering splinter guards

With a down cut blade, you are going to get ragged on the side of the work piece away from the saw. It will also want to push the shoe of the saw off the work piece.

With an up cut blade, you are going to get ragged on the side of the work piece against the saw but it will pull the saw toward the work piece. If you then add a splinter guard, you won't get ragged at all.
