I have broken teeth off of those bits, but never had them come apart like that. Scary

Wow, that is crazy. I use those style cutters also and never have had any problems. I could believe maybe one failing from a bad casting, but all 4? A guy would have to imagine that every one the guy at Carlisle was selling is crap.

Real good to see you didn't get hurt! Selling cheap tools should be considered an act of terrorism....

30,000 rpm? What are you, drunk or on something else? That's like taking a stock motor and buzzin it at 20 grand, use something slower and that $h!t won't happen. I'd be willin to bet those aren't rated for much faster than 10K RPM. Your more than a accident waiting to happen! Geez, gotta wonder about some people?

I'll walk before I buy anything from HF. About 10 years ago I purchased a battery charger with a lifetime guarantee from that fine establishment figuring "How can I go wrong?"
After returning the third one that only worked intermittently, I found myself arguing with the clerk for my money back. She couldn't understand why I would want a refund on something guaranteed for life, but when you need a battery charger, you need it to work right now.
No more cheap tools for me ever again!

Don't know if the holes you were trying to enlarge were round or not but if they were, my best friend is my cone drill bit. They are fantastic, especially in sheetmetal and aluminum. My garage is ALWAYS only one more tool from being complete... Seriously, thanks for the warning and glad you weren't hurt.
WTF??? Haven't you ever used a grinder before??? :shruggy:
OK, maybe they actually operate at 25,000 RPM - whatever. Perhaps you need to get educated yourself, because they do actually make grinders and bits that do that. You want to use your effin' drill then that's your choice, but don't go flaming people who actually want to use a proper tool.

bet the seller at Carslisle bought them at swap meet or HF and made a few $$ from a lot of unsuspecting people.....
I bought some drill bits years ago, thinking I was saving money...they would not cut wood...and I could bend the bits with my fingers using both hands

Hey PAL! Don't go flaming me for something that he never said what type of tool he used with it! Hammer drills go at about 10K RPM. I have never seen a grinder go over about 6, maybe 7K RPM. I want to know what kind of tool he was using to go 30K RPM and what the rated RPM was for the bits he was using! So keepa you mouth shut until you have the answers, and don't disin me for a valid point!

The 30 grand got my attention, too. I don't want to be next to anything turning up that high, much less hold it in my hand.
No doubt the bits were crap anyway. In the early 90's I bought a cutting bit like the 3rd from the left. Got it at Grainger, and it still cuts after 20 years. Body shop use, not home owner use.
Things I won't go cheap on are things that spin or take impact, like hammers, punches, chisels, etc.
Look, I don't go looking for fights here on FBBO, but you say don't go dissin you for a valid point?. You think saying I'm drunk or on something else is a valid point? Maybe saying I'm more of an accident waiting to happen is a valid point? There is no reason for inflammatory crap like that.
And for your reference of never seen a grinder over 6, maybe 7K RPM. These are just two examples. They are all over the place, and lots of people use them...

OK, so you got a grinder that does xxxxxx rpm. Were the bits rated for that? Sounds to me like you bought cheap bits not designed for what you wanted to do with them, and now you're trying to deflect the blame to somewhere other than where it belongs, which is squarely on you. So far, you've blamed everyone but yourself.
Your original post should have gone like this; "Hey guys, a word of warning. Be careful when you buy grinding bits, not all are rated for high speed. I bought these bits from a guy at Carlisle and after putting them in my 30k rpm grinder they bent and broke. I was lucky not to get hurt. I just assumed they were OK without checking. My mistake. Always check to make sure that the tools you buy are suitable for your use."

Ummm........Don't work with tools much? My air driven die grinder's & cut-off tool's are all rated around 30,000RPM. A lot of air grinder's/cut off tools are rated between 20,000-30,000 PRM. Heck even my dremel and dewalt electric rotary tools are rated over 30,000 RPM.
Before coming in on a thread tastelessly bashing a guy, you should probably do your research first, and be able to back yourself up. I'd guess anyone here could do a quick Google search and easily find power & air tools that run up to 30,000 rpm, and a ton of grinders that run over your estimated 6-7K, but what they won't find is a hammer drill running 10,000 RPM,....try more like 2000RPM or so. You'd be destroying drill bits and snapping your wrists off with RPM like that on a drill.
How about just trying to be respectful & courteous next time? What's wrong with that route?
:evil5:A Dremel tool spins at 30,000 RPMs.....
The vendor at Carlisle should be the one getting the negative comments...

It is a shame this thread got so ugly. That wasn't the intent.
First of all, I do make lots of mistakes, and I blame myself regularly when I do stupid stuff. I haven't gone blaming anyone other than the "crap tools".
Yes, it is buyer beware, and I learned my lesson never to buy unlabeled bits. But I did not just assume they were for my grinder because I asked and was told by the vendor they were for high speed grinders. They obviously are not rated for the speed, and on account of that, are dangerous to use in a high speed grinder. The part I own about this was taking a chance on unlabeled bits. Maybe the vendor misheard my question, maybe I misheard his answer, maybe he lied. Who knows, but it still ended up in a bad situation.
I did react to being called drunk and dangerous - there is no reason for that. I bet many folks buy tools, especially consumables, at Carlisle. So I will leave it to suggest that people not buy high speed grinding bits that are unlabeled. Maybe we can all agree on that...

You didn't do anything wrong! Some people jump right into attack mode for some reason. I have a grinder that spins @ 30,000 rpm. I learned a while back not to buy the chinese crap that spins quickly. Even the cheap cutoff wheels come apart very easily.

Look, I don't want to pick a fight either, but when you make a comment about if I have ever used power tools or not, I think your picking a fight! Maybe my comment about being drunk was being outta line, so be it, water over the dam! I will admit this, I don't own or have any pneumatic tools so I have no idea what RPM they buzz at, okay? BUT, if the OP had stated what tool they were using that buzzes at 30K, and what is the rated RPM of the bits in question, this crap may not have happened. Until such questions are answered by post#1, I will stand my ground by what I said earlier! I'm done with this!
