Knotted wire cup brush help needed

[GophersGarage]

Hi guys I wanted to get a replacement 3" wire brush to replace my cheap china one I have right now.

I see Milwaukee sells one that is Stainless Steel knots vs Makita makes one that is high carbon steel knots.

Whats the best to get? I was thinking to go Makita since in my eyes carbon steel is better for rust removal

I am looking for made is Canada/USA products

Amazon.ca

If it's just steel your going to using it on then go with the Makita, if you for some reason need to use it on stainless or aluminum then it needs to be stainless

Too add a SS brush, if used on steel will be contaminated and should not be used on the aluminum or the SS.

What's the COO on that Makita?

 

[GophersGarage]

I thought Makita was Japan

ps found this one

When I was in the HD store they only had the SS version but now I see they have a carbon one and made in usa. I just feel the Makita if japan is a better unit

Making sure what you are using for is important, ie stainless work.


But for quality look past name brands in HD and look for Weiler, Pferd, Walter.

Country of origin in this case typically indicates quality, my Weiler cups laste 5x longer then my harbor freights.

Weiler brushes are available online at several outlets including Amazon, Zoro, and MSC

I go through a few of those a year and the best ones that I've used are Weiler. The cheap ones will throw wires out continuously - always always wear good eye protection, and the wires wear down to a nub pretty fast.

Unfortunately I cannot tell the difference from a bad one to a good one until I start using it.

It is a consumable , so country of origin doesn't matter.
A little tip here:

Never use them on a grinder as they fly to pieces .
I use twisted wire brushes on a "sander polisher" [maximum RPM is 3600] and can wear them down to nothing.
You can also really lean on them at lower speeds.

My cost of these consumables has gone down 20:1

A variable grinder is the best for any type of wire wheel. The slower speed as mentioned will definitely increase the life of it.

Even using one on a variable speed Dremel for fine work is a plus.

Depending what you are using it on, I bought this Eastwood Contour tool . It takes 4'' wide and 1'' wide wheels/drums. The thing is great ! I

do metal artwork and on flat material it's awesome. I have the 1'' wide that I used on horseshoes. All sorts of wheels avaiable.

I think I can use a little education... I have heard about this contamination before but don’t understand it. I do understand aluminum on grinding / cutting wheels but what exactly gets contaminated when using brushes on dissimilar materials?

Only really applies to welding or when SS comes into contact with chemicals/liquids etc... like food industry or chem plants

ex: you weld a SS pipe for delivering beer at the local brewery, welded area was cleaned with a wire cup used on carbon steel, the area will have contamination resulting in poor welds that could leak or contaminate the beer.

DrClyde would have excellent insight into this

That was my thought also. Until I used some Bosch German made 4-1/2" cut off wheels and Dewalt Canadian made. They lasted two to three times longer than my Menards cheap Chinese ones. I still use the Menards ones most of the time, however when its something that I need to keep a full diameter, then I use quality. Was using a Dewalt Chinese 3" crimped wire wheel on a grinder and it lasted just as long as the Pferd german ones, and Milwaukee USA made ones. Any how there are my experiences.

I personally don't care for "Knotted" wire wheels they do last a long time, but I find on the projects I have done, they just don't cut [clean]! The simple crimped ones cut way faster for me, but at the expense of life expectancy [wear is exponentially faster]. I will re-iterate, wear a full face shield and safety glasses, because as mentioned above projectiles are a guarantee the cheaper the more you will get! I have had a wire stuck in my eyebrow and the blood that flows [fast I might add] will make seeing hard [yes I had safety glasses on but they only cover your eyes, and the rest is in play. Also be aware that each has it's grabby spots and not necessarily the same places you might expect, so keep some distance between the soft bleedy spots and the weapon in hand. Harry

Heavy pants are a good idea as well. You don't want one of your 'nads punctured by an errant wire.

Not to high jack the thread but for cleaning a rear end of a truck what would you use? Knotted steel?

I used them last week for about four hours straight cleaning up all the metal on a 40 foot trailer I was repainting. I had steel barbs sticking out of my pants and unfortunately my legs and shirt. I wear a mask and goggle type safety glasses. Big job but the only way to get something like that done is a few grinders with various knotted wheels.
