Toolholder tightening fixtures - CAT40

There are basically 3 types here: The first couple seem to have two parts, then the Huot clamp type, and toward the bottom, the kind I have, the "rotary" for $100, except mine is without the rotatry, you just drop the fixture into a vise.

I'd like to bolt something to the side of the Fadal, and I thought I had seen something that bolts around a *corner* edge.

What do people here use? Any other types of these fixtures? Any preferences for any particular one in the above link? Not sure what the pro's/con's are to each style. The one I have is not so great for long pull studs, or even getting to the pull stud.

Does what I need. Have the same type in NMTB 30 as well. Both are welded to a bit of 1/2" plate thats lag bolted to a workbench. Doesnt do studs though.

If you're going to be changing out pull studs frequently then get one that mounts the tool horizontally.

Be aware that studs can only be removed & replaced a finite number of times before their strength is compromised.

That's interesting, I don't believe I've ever heard that emphasized before . While I was at Avion we used the same pull studs for like... hmmm, 15 year s without one breaking. They were changed all the time so the same toolhol ders could be run in the Fadals, and the Haas (which take different length pull studs - for those that don't know). Had a couple pull studs loosen wh ile in the machine. What a God-Awful noise THAT made. Didn't do the insid e of the spindle any favors either.

I proly won't change studs that often, but I think I won the bid on a unit that can be mounted either vertically or horizontally unit, either on a table OR on a cabinet face, which is where I'm going to mount it (fadal cabinet)

Horizontal has other minor advantages, as well, ito tool insertion at a given protrusion. Mebbe I'll split the diff and mount it at 45 deg.... lol

A little known but apparently quality company makes this, American Sun.
