Question: how do they wear
Document: I've used about a dozen of these on an auto restoration project, removing rust from sheet metal. They really work well and outlast other similar abrasive wheels I tried, lasting several times as long. Even so, they do seem to wear out faster than I'd like. I think they last longer if you back off on how much pressure you apply.I've found them locally at Sears. Some people call them "rice cake" wheels, by the way.
I have to maintain dozens of old buildings, many of them that are painted log or 1/2 log sided. I started using these several years ago to strip paint from these "non-scrapable" surfaces, and they work great. You can apply as little or as much pressure as you need and they never clog. It's the only solution short of sandblasting that I've found to effectively do this job. If you need a lot of pressure or use on sharp surfaces (irregular log knots & limbs, etc) they wear pretty fast, but they're worth every penny.
You can have great results with this product! Let it do the work. I use this on logs when building log furniture. I can take very little material off leaving it smooth, or I can really dig in and remove material for dimension. Works great on uneven surfaces. I wish they sold them locally here. I cannot get them at home depot anymore either:( NEVER CLOGS, even with wood or finishes. Buy it and use it! !
Worked well at stripping old paint.
We use this for cleaning up repair work on concrete floors. When used properly (let the pad work don't try to force it) it will clean the surface without damage>
This disc has lasted me a long time. I've had it on my grinder for a couple years and use it more often than I imagined I would. I was impressed when it allowed me to grind down a solid brass but to make a custom plumbing fit. The material doesn't fly off or disintergrate like a cheap version will. A good quality grinding disc.
These work great for stripping paint off metal. Does not damage the metal. I used these to strip the paint off the steel of a horse trailer. Makes a smooth finish and is easy to use. The best tool I have found to aggressively take off paint without grinding down the metal. Great product!
These disks are effective for stripping paint, but they don't last too long. They are vastly superior to wire brushes for the same purpose. Make sure you buy a few unless they are needed for a tiny project.
These are great for removing paint and rust without removing metal or throwing little metal spears around like wire brushes do.
Stumbling upon this Rapid Stripper was a marvelous find. This is one great product!Shipping speed, price, and product were all great.Thanks
