I have an el cheapo harbor freight that works but just doesn’t have enough *** to run roloc discs efficiently. Any suggestions?

Alright quick search on Dotco and going with s firm no. I’m thinking non aviation grade, poor man budget... thinking more like Chicago pneumatic, air car, ingersaw range...

Any good composite grip from taiwan will work great,
I prefer the shallower angle to a 90' myself;

I wouldn't spend more than £60.
Astro do a kit with a straight and 90' for less than £100;

I bought the straight version of this IR a few months back, and its been a brute. My current 90* is starting to show its age and will probably be replaced with this one when the time comes, $60 https://www.amazon.com/dp/B000VYZ1HW/?tag=atomicindus08-20

Yeah. Are you sure your compressor is up to the task? Grinders like this use a lot of air. I had similar problems until I upgraded my compressor. 7.5HP and 23 SCFM make a LOT of difference.
This Dynabrade Red 18160 for 2" or 18180 for 3" discs is good value and tough little tool. This is a direct drive gearless tool which is the most efficient design for quick change discs.

I bought a husky one on clearance from home depot. It is still on the website but I have a feeling it is discontinued. the one I have works awesome and seems well built.

80 gallon 2 stage compressor so fairly certain that isn’t the issue

I had been looking and contemplating that one already just having some issues pulling the trigger. I was also looking at the max version and even though the locking arbor on it locked handy too many peoples complained about it locking up/breaking.

While it’s a little more than I really wanted to spend, I think I’m going to have to do a little research tonight on in.

The straight one I have has some nice power to it, and I cant really imagine needing more for what I use it for, mostly sheet metal work. I haven't used one of the Max versions to try the one tool locking collet, but the collet on the 3107 one seems more robust than the one it replaced, but for some of the attachments, it can be a little snug getting them in and out. It does have some size to it, that I would assume would carry over on to the 90* version, not really a hindrance, but for tight crevices, it can get in the way a bit.

I recently bought CP875. Mine is an older model NOS from ebay...looks identical but the new case is red. Its powerful for its size, but its smaller than expected.
I'd buy it again. Good value

Thanks for the info I appreciate it.

I use a die grinder mainly for surface prep in restoration work, with rolocs of various flavor. The ergos on a 45 are so much nicer, and i’ve never once wished for a 90 back.

I have both that CP grinder and an IR301. They are equivalent and I use both quite a lot. No complaints about either. I use both with roloc wheels and wire brushes.

+1 to the 45 degree. Much easier to work with.

875's and 876's are nice tools. Can't really go wrong there for the money. Both are mini sized, which is mostly handy for general use.
If you want to dig hard with 3" Rolocs, you'll have to step up to bigger budgets. SO, Dynabrade, Etc.
I've wanted to try, but haven't yet St Louis, everyone I've talked to has been pleased.
