I bought that grinder myself. Burned it up in a day. About 3 hours. Bought the better one. Took 2 days. Bought a Dewalt. That was 3 years ago.
Burned out the HF oscillating tool. Got the Dremel multi max, am happy. Started with Dremel moto-tool 35 years ago. Still have my first one.
Now have 6. Good medium range tool.
What are you comparing Dremel to that it seems like junk? Something comparable?
I can't speak about the newest grinders that HF is selling but that old orange one has lived a hard life & holding up well. I bought the blue one I think about 10 years ago first to keep a grinder on one & a brush on the other but it ended up seeing some hard times also. Running it as a wet cutter for concert block. I DON'T SUGGEST ANYONE USE THIS AS A WET CUTTER. Only problem with them has been the blue one had a screw on the wiring lose that cause some smoke & took me 5 minutes to fix.
I finally bought the Variable Speed Oscillating Multifunction Power Tool that had been returned so it coast me $10 I think. I don't know which item number without looking tho. I love this little saw. I use it all the time also. I even way over work it mostly cause if it is in my hands I don't want to go get the right tool.
I have used Dewalt, Dermel, Bosch, Skill, Black & Decker, Bluepoint, Porter Cable, Hitachi, Milwaukee, Makita, Ryobi, & I'm sure there has been others. I didn't include store names or one time use tools.
I loved Porter Cable back in the day. They were a little ugly but lasted well. The top names are not what they were 20 years ago. They are just as junky as anything you get from HF. I have had the best luck out of Hitachi over all. Of I need a part for one of my HF tools I usually look to one of the other name brands to get it.
Not to belittle your opinion but it really sounds bias to me. If your really having that much terrible with power tools I suggest keeping in mind where your hand placement on the tool is. Covering up those air holes will kill them fast. That is another thing I hate about the Dremel, it just seems to naturally drift in my hands to where I'm blocking the holes.
As far as is the HF multi grinding tool better then the Dremel? I don't know. I don't have a HF one & only used it maybe an hour total. I also don't use these too much. They are light weight but have a purpose. I use them when I get in a bind.
I'm not a brand hatter. I hate paying more for the same thing because of the brand.
I had a painted gas powered tool one time that the sticker fail off & showed it was another brand before that. The Matco tool man showed me a box of putty knives that one was his, Snap on, & Mac.
So are you sure you are really getting what you pay for?
