A favor to your angle grinder

[dstig1]

You want to do a real favor for your angle grinder? Try this stuff. I have a friend that works in the group at 3M and he gave me a few extras they had sitting around in the test lab. He told me how awesome it was, but there was nothing like the first trial to go "HOLY CRAP!" This stuff is amazing. I was grinding away at my snow plow build with a regular flap disc. I figured I wasn't getting a lot of progress, even though it still had a lot of life left, so I put one of these on for giggles. I was grinding away for 20 min before. I finished in like 2 min. It went through metal like something really witty that I cannot think of to put here. Insane stuff.

Well it better work for $10/disk!?!

Does it last 4x longer to make up for the price difference?

Thanks

Maybe I'm just a splurge but for no more than a new one costs I'll just buy another if it quits, good for the economy too lol

I can't say for sure it lasts 4x longer, but it sure will last a lot longer, as it cuts through metal like nothing I have seen, so you will finish faster (and it's not like it wore away to nothing doing that - wear was nothing unusual for use time). Less time should equal less wear. Plus if you are looking at the 3M list price, you should be able to find much better pricing than that (I found $4-7/disc depending on grit with a quick amazon search 3M Cubitron II Flap Disc 967A, Type 27 (Multiple Grades/Sizes): Amazon.com: Industrial & Scientific). Of course, I got mine for free, so it is hard for me to judge cost

My friend told me their sales reps would show up at big accounts with a couple discs and tell the guys to "go try them. I'll wait in the lobby." They would come back in 10 min with eyes as wide as saucers drooling over these things. Instant sale. I thought he was BS'ing me too, until I tried them. I figured they were for sure better in lab tests but maybe not noticeable in use. Seeing is believing. I was stunned.

Never really thought to do that. Great advice!

Ditto, I'm heading out to do that right now before I forget. Thanks

Around here, (LOWES) sells Dewalt flap disc for around $10 also. I wish I could find them for $2.50 each. It seems all abrasive products have sky high pricing including the el cheapo quality ones from HF.

Luckily I have a friend that gave me a good supply of flap wheels and Norton 9" "Pipeliner" grinder blades. I don't think I will ever run out of 9" blades but I use the flap discs a lot sharpening my and neighbors mower blades. They work just as fast as grinder disc and don't heat the metal as much plus leave a smooth finish.

First thing I do when I buy a HF grinder for cheap is take off the cover and jam more grease on the gears. It definitely quiets them down. Seems like they skimp on the grease and it is already flung off as you mentioned. Good tip![/Q UOTE]

Agree!
I have 2 grinders (Makita)that I got 12-15 years ago that get used a lot.
Compressed air and periodical grease management is what prolongs their life.

A buddy who simply does not understand maintenance burns up about 6-7 a year.

I discovered that on my own too.. There is nothing better to sharpen a mower blade with in my opinion. Beats the heck out of a bench grinder.

How do they work on removing rust and old paint? About to refinish a FEL Bucket.

I almost never use a bench grinder anymore.

Also almost never use a regular grinder disc either unless using the "End" like grinding out a crack or weld. Always try and use some type of flapper if I can.

Will probably work, but likely load up like any other flapper.

Get something actually made for paint. Just search paint stripping disc.

Yeah I am now a big fan of flapper discs and continue to stock up when I come across a good deal.

Paint and rust, no problem, in my experience. You run into issues with any abrasive when you are trying to remove lots of millscale, as that is super hard stuff. Now if you are dealing with really heavy paint, you might want to abrade that away with a wire wheel first or it might clog up an abrasive disc, but I wouldn't worry about it for regular stuff.

I will never use a wirewheel again after using them scotchbrite things.

No vibration, no flying wires, lots faster.

Good advice on the grinder grease. Never thought of it either and I have the same 18 volt grinder as the op. It also seams to be noisy now.

Will have to look into those scotchbrite things. I always used a braided wire wheel they don't seem to come apart as bad as the straight wire ones.
