Grenaded a freewheel tool...
Found a random wheel with a Sachs LY 96 freewheel, M700 high flange MTB hub. Freewheel frozen, but salvageable, and figured the hub was definitely worth salvaging.
Hit it with some PBB to loosen up the freewheel and sit overnight. Freewheel started to spin once the grease dissolved, but the freewheel wasn't budging off the hub with standard force and a 24" adjustable wrench. Slapped my Shimano fw tool in the vice and gave it a couple torques... SMASH! Shattered to many small bits.
I bought this one on Amazon a couple years back to replace my Bicycle Research tools. Knowing Amazon, it's entirely possible it's not even legit, there's so many knockoffs on there anymore.
Anyone seen similar? I've definitely put more force into others. No clue why this blew to bits. Yes, I was definitely spinning the correct way!

Park tool stands behind their product with a lifetime "you bought it, you got it" guarantee.
They say they are forged, I say they are cast. I'd bet money on it.

That tool does have a thin wall on it. And that is some damage on the tool. Wow. It was hardened. That is for sure.
All I can say is try it again with a new tool or bring it to a bike shop and see if they have better luck.
Heat often helps as well. If things get to the point that you break another tool, dismantle the freewheel so that you can heat up the only inner part of the freewheel without heating up the rest of the freewheel and try it again. Keep cycling the heat until it gives. It will come off.

I still have the wheel. I'm actually going to try heating the freewheel, and hit it from the backside with PB to cool it, sometimes that'll wick penetrant up between the metals as it cools. I just don't know if I want to risk exploding another tool. Definitely not going to throw my Bicycle Research version, even though it's thicker-walled and I think he machines from solid block vs. cast+harden, I don't want to grenade it also.

I have the Park FR-1.2 which has similar thin walls. Never had a problem, even with prodigious torque applied with my 3’ long pipe breaker bar extender.

For S&G, I ordered a couple off the old scammerzon site. One from VANICE, and another from Bikehand. I wanted to try the BW brand, looked similar to the VANICE, the longer body looks appealing. Will see how it goes.

In the iffy advice dept, I use a very low powered air impact gun on some stuff like this. My big one would do what just happened, blow the tool apart. My really low power one with air adjustment dialed down sort of beats/vibrates the stuff apart without damaging the tool. You really have to know your air tools to do that. YMMV

BUMMER!
I had a Campagnolo crank removal tool shear in half, if that counts. It broke right at a stress riser which coincided with where the wall was thinnest.
At the time, I was devastated. Obviously, I am still disturbed by it.
I do still have the "peanut butter wrench" that went with it when I purchased the pair.

Those Campy PB wrenches are the best. I dunno what the hell I'd do without mine. Out of all the tools I own, it and my Campy t-handle are king. I could live without half my tools just having a pair of PBs and one t-handle.

my guess (and I'm not a metallurgist, not even on TV) is this was just "bad luck" due to the tool being thin-walled, cast steel (and prone to having some hidden defects in that casting process) then heat-treated to make the splines "harder" but the entire tool more brittle, which is a trade-off.
If this had been made by forging and then finished machining it may not have "exploded" but probably cost a great deal more and there are still other ways a tool can fail (broke my heart when a beloved VERY thin-walled Phil splined FW tool "collasped" on me! But my replacement, same tool, has held up).

I've broken thin-wall Phil removers, and Park's two-prong SunTour removers, but not (yet) a Shimano TL-FW30.

I look at those hubs and those removers and simply think that's collectively poor design to have one of the most highly torqued tool used on a bike to have that little material at the key spot. And yes, a delicate balancing act between hardness and strength with the real answer being more material.
Both Park and Shimano make good tools. But designing (or not designing and simple following along and making) FWs and hubs that require that thin a tool - well we really need a new metal that is substantially stronger and brittle failure free than steel. Or live our lives dedicated to the notion that FW threads will always be properly greased and not sit for years and decades, then removed. Or just accept that every once in a while, those tools break. (A good reason to clamp them in a vise and turn the wheel with both hands vs using a big wrench. Much less exciting. You don't slam your hands into things.)

Know your compressor, you mean? You could just dial down the regulator for less kick, right? I contemplated throwing my electric IH on it, but the only impact socket I have in that size is 1/2" and my IH is 3/4" drive. I lack an impact reducer for that stepdown. I thought about whipping out my butterfly IH to feather it out. I can't seem to find that damn thing. I found my impact chisel. Not sure where my butterfly went. So much of my stuff is boxed right now...

That may be true about Park Tool's freewheel removal tool(s). But the OP's tool - or what's left of it - appears to be marked "SHIMANO TL-FW30".

Other, thicker-wall tools were available for the Atom/Regina/Zeus splined interface, but those often required removing axle locknuts to seat the tool. In the case of Phil hubs, this wasn't possible, which is why they produced their extra-thin remover tool. That tool became popular with other hubs as well, since there was no need to remove the locknuts to seat the tool.
