Dremel or die grinder for a very tight access space?

[Jacobson]

If I wanted to grind something down that was in a tight space (no cutting wheel), what would you use? What attachment would you use on a Dremel for grinding down metal? Is a die grinder a lot stronger than a Dremel?

What rotary tool accessory is correct for grinding down metal?

A 1/8" pencil die grinder is even smaller than a dremel

How many seconds would a 6 gallon tank run a pencil grinder for?
What attachment do I need to buy to grind down metal?

Your Astro brand is the first search result! I might get this.

Agreed pneumatic 1/8in pencil grinder with burr tool or Circo-file

You can always use a cable-drive attachment for a dremmel too, then you don't have the body of the tool to contend with:

427.6 seconds

Heck, I don't know. What CFM? Are you stepping down line pressure? Running it non stop?

1/8" carbide burrs

I agree. I have both a pencil grinder and a Dremel type tool with the flex attachment, I'd choose the pencil grinder every time.

I have this but am not sure what attachment to use.
I used 407, but it sounds like I should use 8193

 

[Jacobson]

Do those Dremel attachments fit into the pencil grinder?
It looks like the Dremel is 35000 RPM and the pencil grinder is 55000 RPM.
I might try again with the Dremel and use the correct attachment.

compared to a die grinder a dremel is a toy

 

[Jacobson]

I hear that, but for my application, the toy might work with the right attachment.

I see a huge price range for carbide burrs.
I see a set of 1/8" Carbide burrs from $10 to $100.
Are those cheapo sets junk that just looks like the real thing?

I have a Dremel with the cable drive attachment as well as straight and angle die grinders. The die grinders with carbide burrs are hands down better for grinding metal. With a good assortment of burrs you can grind pretty much in any nook and cranny. The Dremel has it's place for sure, but for me that place usually is on the shelf while I use my die grinders for metal.

In almost every instance that question could possibly be asked, yes.

sure, sometimes if you need a really precise cut and time has no value ... I guess a dremmel can deliver a better result (no damage to the part )

whadda coincidence.
had to use a dremel, which i usually dont carry on the truck, to enlarge the bore of a fitting. had only (3) grinding wheels, of different sizes, materials. they all got boogered up with whatever pot metal was in that fitting
circo file. burrs. thank you. i need to visit mc master.
dremel has a poor selection, it seems. stopped at menards, and bought whatever they had. (not much)

This.

I had to grind off a mangled hose clamp in an engine compartment where I could barely reach my hand down and touch the clamp - couldn't see and had to work by touch. I used a dremel with the flex attachment and a grinding stone like the 8193. Worked pretty well, much better than my initial plan (I immediately thought better of it) of using a cutoff wheel. I decided I was more likely to retain all 5 fingers and more blood if I used a grinding stone. It was a little scary, but ended up working well.

 

[Jacobson]

What's better for grinding softer metals?
The orange stone 8193 attachment or the carbide burr thing?

I need to grind down some aluminum.
It will be a 1 time use.
Should I get a double cut burr?
Can someone recommend a carbide burr to buy?

I'd rather have one good one than a set of mediocre ones.

Those burrs from Amazon worked out great for me.
