Anyone use one of these? Or know what they are called? I'd be looking for an electric one.

Wondering how well they work for removing dross and sanding down so the metal can be ready for patina

$300.00 will buy a lot of flap disks.
I use a belt sander, after removing any heavy dross with a quick swipe of a twisted knot cup.
The flap disks are prone to gouging and I try to avoid that as much as possible - especially on the 'front' of a piece.

lol that's why I want an electric one. I burn through flap wheels pretty quick.
I HATE twisted knot cup. I don't think it works well at all. I even turned it sideways to get the meaty part of the knot to hit and it flings stainless strands everywhere. Had one sticking out of my hand. No thanks.

I can assure you that thing will throw also . . .maybe not as much, but will throw.

We used to have one similar to it in an industrial version they used to make welds pretty in a Budwieser plant in the process area in Bakersfield.

Since I've started using the Norton Avos sanding discs, I use very few flap wheels. And the Avos discs last a long time.

The best wire wheels I've found are the ones I get from my local NAPA store.....I use the knotted ones and keep them pretty flat on the surface when using them. Takes 90% of the dross right off. They cost about $12 or so and last a good long time, with little wire loss.

I also have been happy with flap wheels made by Camel. I get them from ENCO. They are about $3 ea. if you buy a box of 10.

Just my 2?

It should work, my concern would be longevity of the media and cost to replace. If you end up getting it run it for a month and let us know. Thx

I use the twisted knot brushes on almost everything. I don't think you can find anything that will remove the dross faster, but they are dangerous. They will grab your shirt and whip your a$$ before you know what got you, lol. I have the scars to prove it. The main point I would like to make though is that if you have dross that a wire cup brush won't easily remove then you probably have other issues. I don't have experience with anything but Hypertherm but if you have your machine and table properly set up you should have very little dross and what you do have should be easy to remove. It is much more economical to take the time to set everything up properly and keep new or undamaged consumables in your machine than to spend time cleaning parts.

Agree 110% fix the cause and you don't have a problem, I cut a lot of 24" x 18" oval signs which take about 30 seconds each to do with the wire wheel on the grinder if they need doing at all.
I've wrecked a couple of shirts too :oops:

What do you expect from a Harbor Freight wire brush?

Stop buying crappy tools and being disappointed with the crappy results you get.

You have to look at the value of an item, not the price.

Norton Avos sanding discs are the way to go for light dross removal. On heavier material with slower cuts and more dross I use an air hammer with a wide flat blade first and Norton Avos sanding discs for the finishing touch..

Fwiw, I've been picking up my abrasives at http://www.grindtoolabrasives.com and have been really happy. I've been getting 9" PSA green zirconia discs for my grizzly sander and they work fast and last about 3 times as long as my previous vendor. I ordered some flap discs and 3" Roloc stuff. I found the guy from Pirate.

I have been using a wire cup on a air powered buffer. Turns a lot slower and it's a lot safer !!
