Is a Die Grinder or Angle Grinder Quicker at Paint Removal?

[calandrod]

I’ll be stripping paint off of a large round aluminum surface. I started using my die grinder with a strip disk. It works great and quick but this surface is really big.
Will an angle grinder with its 4” strip disk take the paint off quicker than the 2” die grinder with its 12,000 RPM’s?
If anyone has experience trying both, it will save me the cost of running the experiment myself.

A 10,000 RPM 4 1/2" Flap Disc can work wonders until it gets loaded with paint.

I’ll specifically be using this style of strip discs. That being said, I was just looking into the RPM on the angle grinder and to my surprise it appears pretty close to the die grinder rpm. I thought it was much slower. So I’ll have to give it a try.

How large is the surface?

If a large area needs quick stripping I would look into a "Crud Thug". Link Below.

This one strips paint rust and polishes to boot. I have one and its pretty cool. Used it to strip paint off some tool boxes

The Eastwood Contour (or its Harbor Freight equivalent) is the answer as given by flyingblind. Get it with the stripping drum and you're all set. Has many other uses as well.

The strip disk on an angle grinder is very fast and effective. No need to spend money on a special tool unless you expect to be doing this a lot.

Ive got a corded full size die grinder and a 4" A/G. I'd say for sure the A/G has much more torque and is better suited to run larger size abrasives. Die grinder is a 1/4" collet and I wouldn't want to run anything more than 3" max diameter disc. Angle grinder be much more comfortable with a 2 handles putting in some work.

9" Milwaukee 2-handle sander and whatever abrasive you favor, should make short work of things. Those sponge-looking abrasives do a good job, even on powdercoats.

Incidentally, I just am refilling my same tool 's grease vault, and I found out the G grade of grease as recommended by Milwaukee has been superseded in all applications calling for it, by type Y grease. 'The Word,' from Milwaukee's hot-line.

The type Y grease becomes liquid under load so it flows into the gearset, where a thick grease would just get flung-off by the rpm's, and not perform adequate lubrication. When the type Y grease cools it becomes more-viscous.

What you're describing is John Deere Corn Head grease and it works in exactly the same manner. I've been using it for years on all types of grinders and polishers for exactly the reason you mentioned.

In most situations like this the bottom line is POWER. The more power you have that can effectively be applied to the job at hand, the faster you will go.
Your description of the job at hand is lacking in a lot of details. A large round Al thing could be a puke tank on the side of a radiator or the fuel tank hanging off the side of a semi truck. A large round with a 2" radius will be a different tool than something with a 30" radius. That is where the word effectively comes into play in my first sentence.

no neat sig line

I use a pneumatic 4.5" angle grinder with strip disks, they are definitely faster than the 2" discs on a die grinder. I tend to not run these at full speed, I find lower speeds work just as well. I'm usually working with steel, so I can't comment on aluminum much.

Another vote for the Harbor Freight surface conditioner. Works well.

A needle scaler will damage your aluminum, so avoid that.

I think you may have mentioned the JD corn head grease in another topic?

You know, I just assumed she could see what you were typing in that post and you were trying to score some brownie points.

Use the angle grinder with the strip disc. Or an air sander with a strip disc you won't regret it

i usually go for the biggest tool i can fit to do the job.
a 7" grinder will do the job faster than a 2" will
