Can a Shapeoko XXL/Dewalt router handle a 1-1/2" V Groove 90° for MDF?

Like the Amana Tool 45728 V Groove 1-1/2" 90° ? Need to make a v cut 18 mm. deep, 36 mm. wide.

Handle is a broad term.

It can spin it and cut with it. But That bit isn’t balanced well and will vibrate that trim router to death.

If you do attempt it cut with 1/8” depth per pass.

When I tried this tool, it vibrated so badly that I immediately turned things off and put it away.

My recommendation would be to do the trigonometry (or draw the cut up in profile) and make multiple passes to arrive at the desired angle.

I showed doing this in:

Thanks. Recommended settings, speed … ?

Wild that was the exact same thing I thought about the SPETool version with the single TC insert. I think I let it cut an inch before I said this is going to cause long-term problems for this machine.

I have to cut V Groove 18 mm. deep (36 mm. wide). Doing it in multiple steps with a smaller tool is a pain, if there is just the slightest inaccuracy.

Gotta learn to draw it out with trig and work in mm instead of inches as the machine works in mm.
Other option involves a tool swap where you once again do some math but this time you do less math and hog out a majority of the cut with a 201 or other endmill then do a pass to remove almost all of the rest and then one finishing pass as that bit has too much engagement so DoC needs to be shallow.

Thanks, I will try that.

For V Groove, it also becomes a problem if the base plate is not 100% completely flat. I wish there was a way to tell the machine if there are +/- 1/2 mm. local varieties.

Tram the router and then surface the wasteboard and you shouldn’t have that much variance.

It may be more like lightly surface then tram then surface again to get the best results.
