This is a must-have for engine work knowing we don't actually put new valves new head new block every day. 1 valve changed, put all the old stuff back together, you need to clean the surface real good and not take too much material. These discs are expensive, 1 case usually last me a year or more
That will start a conversation that never ends. Many don't recommend it, others say it's safe, if you're careful. We're right in the middle. We'd definitely recommend you using the White (120) disc on aluminum, and don't sit in any one area, keep the disc and tool moving. Thanks for watching.
If you use the correct one for alum it's safe; but, according to a GM TSB from once upon a time they say not to use them on in-place engines. Not because of material removal but because they create a *very* fine dust which, if it gets in the engine, cannot be filtered by the oil filter and can cause premature engine failure. They basically say don't do it on things like head gasket replacement. I honestly think that's just a worst case scenario warning though as lots of people use these and it never rarely causes an engine to fail. Might want to be extra careful in cleaning everything up; also change that oil right after running it a short time.
That's a tough one. It may work ok, but to do aluminum wheels correctly, then you need to sand them in stages. After sanding, they need to be polished.
@@Shoptoolreviews Lots of things! Where best to buy one. What can I use it on? (Would like to use it to remove aluminum oxidation and rust from my transmission housing and output shafts.) What sort of tool do I need to use it effectively? (Would a power drill work or do I need higher RPM's?) What sort of grits and diameters would be appropriate to my application... I had no idea these existed and it seems like it could make my life a lot easier for cleaning up this transmission. Also my original comment tried to be a starship troopers reference but I dont think that came across at all in retrospect.
Damn it man, you convinced me to buy a set of 10 white colored after watching your full video, since I already have 3 green ones that I have never used till now🥲
@Shop Tool Reviews Hehe, I still don't know how much of a help that will be, since I have a plan to paint my car's hood, and I will have to strip the old dried paint first, and I guess the green one will be the best for the job, but who knows the white might be a better choice, and if didn't I have plenty spaces that has some corrosion to be removed🙂

Worked alot with these things.. im a born sceptic.....these things are awesome AF. Engine blocks, frames, fueltanks etc always worked great and fast

A #3M tem que trazer isso para o Brasil.
They are great for cleaning gasket surfaces, ect
What brand disc holder are you using? Is there another brand that is just as good as 3M?
Settle a debate for me, are these safe for gasket surfaces on aluminum or do they remove too much material?

I work for 3M. Yellow and white on aluminum heads. Green is a tad aggressive.

Need one for my hemorrhoids
Now there's a REAL man
😂😂😂😂😂
Green isbthe most abrasive of the 3 types of 3m. You really should be using white on aluminum.
What grit/color would you use for cast iron?
For cast iron, I'd us the roughest grit you can get. Thanks for watching.
What Milwaukee tool are for the roloc !?
You can use them with drills or die grinders.
Would you recommend for some old aluminum rim cleaning?

Works better on human rim
@@Shoptoolreviews thanks for the feedback.
dont get confused on the collet
We don't, but many do.
What do you mean by this exactly?
Always Debur first
*would like to know more*
Like what?

Advance auto parts sells it. And Harbor freight sells the piece it screws into.

Sorry for the peer pressure. lol.
