3M deburring wheels for 8" pedestal grinder

[Strouty]

I have been looking at these wheels for my grinder, all the 8" ones have a 3" center hole, how are you supposed to adapt that to fit a normal grinder? The 6" ones have the 1" hole? Anyone used these?

You mean the hard, grey wheels? They work like magic. I've deburred my share of tiny machined stainless parts on them. I just made aluminum adapters.

Probably have to make an adapter to run them. Shouldn't be too hard to turn a two piece stepped one.

Burrking makes them, but they are like $100 per set and they are just rebadged 3M IIRC.

As long as your current flanges make contact with the wheel to drive it, all you need is a spacer to keep it centered on the shaft.

Yep, just turn some spacers on the lathe and as long as your flanges can still drive it you're good.

Take a hockey puck, drill the center hole and install on grinder. Power up grinder and turn the outer edge of the puck down to 3".

Why do they have such a large opening? I know it is so they don't have to supply as much material, but are there machines that have a 3" arbor for an 8" wheel?

I will make myself an aluminum spacer on the lathe, just wasn't sure if I was missing something.

I just got myself a couple more grinders and I think I am going to set one up with the 3M bristle brush and the deburring wheel on the other side.

Will the bristle brush hold up to cleaning out threads on grime filled bolts, or should I stick to a regular wire wheel?

The place I got my 6in version gave me two or three plastic tube spacers for free so it would fit the arbor on my bench grinder, but the hole was 1in.

So, one of the grinders I bought, already has a deburring wheel on it, I guess I didn’t look too close at it when I bought it. I just new it was a like new Baldor, it looks like it has the fancy arbor adapter and everything. How did I figure this out you ask...... I tried to grind some stainless and it just got really shiny. LOL, sometimes I am my own worst enemy, there are even stickers on the grinder that say for polishing only, I just hadn’t seen one of the deburring wheels in person, as soon as I touched it I new what it was. I guess I just saved myself some money, now to decide if I want to get the bristle wheel or just use the wire wheel.

I love those de-burring wheels. An absolute must in a machine or fab shop IMO.

They work SO well.

 

[Strouty]

How much can they debur? I mean do you only use them on little parts or can you use them after plasma cutting a 1/2” piece of plate?

They will not take off slag, but they are the best for sheared edges or machined edges.

I use mine to take off the burrs from the saw the most.

You won't hurt it by trying. You'll be amazed at how nice it breaks the edge.

Have you ever used a cratex wheel? They’re awesome.

I am going to have to do a bit of trial before I decide what works best for me. I found a green (60 grit?) bristle wheel for my grinder, new on eBay, best offer of $70 got it. At this point I have a 1 1/2 HP balder 8" with a 2" belt sander on the other side, I need to find out what is best for that, I was thinking wire wheel would try and rip stuff out of my hands with that much power. I also have a 6" grinder and the one I showed in the pictures above. I wish this stuff wasn't so expensive, hurts the wallet to find out what works.

The bristles on those abraisive plastic brushes are too large to get down into the root of normal size threads. If you're looking to clean 1" and up they might work for that.

 

[Strouty]

Good to know, I figured I would try one and see what it can and can’t do.

Be very careful using deburring and wire wheels with a tool rest and full guard. They can grab very easily.

Just like polishers, the high power deburring machines have a guard only over the top half of the wheel.

Deburring wheels are nice, but becarful as they can round a precision edge and oblong holes in a hurry.
