That looks handy, thanks for sharing.

To reciprocate here’s one that I like, it’s a 5/8-11 thread hole saw arbor. Allow you to use hole saws on 7”/9” angel grinder. The one I have is the large version for hole saws over 1-1/4”, but they make one for smaller hole saws too. Certainly helps counteract the torque from big hole saws, a 9” grinder with two long handles is a lot easier control than a drill with a side handle. That long body on the grinder makes a big difference. Don’t use them on a grinder that’s not variable speed, I usually turn mine all the way down.

The larger version part number is 49-56-7105.

Can’t see the part number but that certainly looks like it. To double check the Metabo part number is 316052560.

Thanks, Bob. Pat has a heck of a lead on me. He has a dog, a wife and great artistic skills. (Not necessarily in that order of course]. LOL [emoji23]

Re: Lets talk Flap Disks

Even if your grinder had the normal side handle, it ould be easy to fab up a right extension the screws into the grinder. Then screw the normal handle into that.

You'll definitely love that.
I was gonna buy the METABO until I read about the Eastwood. The three year warranty and inexpensive price made it a no brainer. Buying tool and accessories on that Cyber Monday Sale saved me over a $100.
Those Canadian prices are crazy !!
You're right about Amazon prices. If you know it's a cheap price, you'll always need them, I buy lots.
I can't believe how prices increased there.
Now I always check manufacturers prices and buy from them directly.

Re: Lets talk Flap Disks

Excellent info Pat. Thanks for taking the time to explain and photograph.

I have at least one grinder that allows top mounting the handle but none with variable speed. It would appear if one had these features all they would need to do is buy the extended shaft adapter (or just use the Walter wheels). Maybe add the safety guard.

All good info thanks to you and Mike [emoji481]

Re: Lets talk Flap Disks

Terry,
I missed one of your messagea a while ago.
Here are some more pics of my Metabo burnisher.
It uses the same threaded arbor as a normal grinder and has the extension for the two or four slot attachments.
Once I unscrew that, I can use the Walter drum attachments.
I also have a pic of the sanding drum that came with the tool. It it on the right and has four slots in the center plastic arbor. That center portion came free of the main drum. I put a couple of tacks to hold the arbor in place.
The other drum next to it is the import I bought off ebay. I have not had a problem with it or the original after the tacks.
If you had a variable speed grinder with a top handle or other direction, I wpuld suggest getting these drums first to try out.
It is not that I am unhappy with the tool, just that there are cheaper alternatives to see if you really use them or need them.

It’s late tonight but I’ll see if I can round you up some part numbers on the Metabo shaft extension tomorrow. That said, you might not need it, without having one in hand to look at the Walter may show up with one LOL.

On the type you are currently using you are paying for the convenience of having the integrated threaded arbor nut.

You may be able to salvage a nut off one of your used discs to use on the cheaper plain hole style

The shoulder on the nut fits into the hole in the disc. The backing pad goes onto the arbor first, then the disc, the the nut screws onto the arbor and sandwiches the disc between the nut and backup pad. The disc itself is thin and has no threads, just a hole.

I realize rereading my quote in your reply it was ambiguous if you were used to using a disc with built in nut/arbor.

Search for Resin Fiber backup disc and nut. I’d recommend going with a good brand, don’t want that thing coming apart at high speed. 3M and many other major manufacturers make them, there are backup pad that are smooth for stuff like sheet metal work and pads that are ribbed for cooling when used on heavier grinding work.

I would have considered an Eastwood version but by the time I get it into Canada it’s nowhere near the bargain it is for you fellas south of the border. I’m confident I’ll be farther ahead paying a few dollars more.

Just have to find the economical consumables.

There are two types of abrasives you’ll find for these burnishers, there’s a 3/4” keyed shaft version and 5/8-11 hub version. On the Metabo Burnisher the 3/4” keyed shaft is itself only shaft extension that screws onto the existing arbor, looks like a regular 5/8-11 short arbor on a standard grinder that you then screw the ~4” shaft onto. The shaft extension has two keys that slip into the mating keyways on the drums. Some drums have 4 keyway slots and some only have two, even with Metabo stuff, IDK why the difference but they only use two keys at a time so they can interchange. The Metabo can use either the 5/8-11 hubbed or 3/4 keyed, because it has the shaft extension. If you want to use the hub version you just remove the keyed shaft and screw the drum onto the 5/8-11 arbor. The cheaper ones you see everywhere that have a 4 way key will fit the Metabo and vice-versa.

The Walter doesn’t have the shaft extension, just the short/standard 5/8-11 arbor. The shaft extension/hub is built into each drum, which means, in theory, you should be able to buy the keyed shaft extension for the Metabo and screw it onto you Walter arbor and have it either way, like the Metabo.

A little side note. If you’re going to be using this on stainless to restore grain you’ll want to look for the Scotch-Brite wheels that have the alternating layers of non-woven and sandpaper sheet. If you don’t need a super fine finish and only need to grind down a weld and restore the grain you can get by with one step grinding/burnishing on stainless using only a flap wheel, it’s like a drum style flap disc. And it leaves a super flat looking finish, no wavyness.

I have used the cheaper import drums, and accessories and have not noticed much of a difference in quality. There is quite a bit of difference in price.

Pat does your Metabo have the 5/8” arbor? And where are you sourcing import accessories?

If you don't already have one you will need to buy the thin depressed center nut separately

If that reply is meant for me you’re welcome. Make sure it’s a Quick version and variable speed. They make them with and without both options.

Another thing to note is that mine are 5/8-11 thread, and the shaft has a keyway that the ears inside the nut fit into. I don’t own a M-24 shaft version so I’m not sure the mechanics, but I’m guessing it similar. There is more to it than just having a large nut you can spin off while gloved, guessing it has something to do with safety, which is obviously a good thing as I’ve just learned that I’ve been doing it wrong the whole time. All I’ve ever don’t is hand tight to install, and twist the whole wheel if one becomes a little too tight to get nut off. Lis2323 mentioned that the shaft lock button could be depressed while the grinder was running, and was designed to work that way. I went and dug through some manuals, which admittedly I’d never done before LOL, and sure enough I’d been doing it wrong the whole time. It’s perfectly acceptable to push the button while the grinder is still running to loosen a wheel, on the Quick versions only though. If you’re using the Quick nut and not a disk with a built in arbor the disk won’t come completely off, only loosen. I’m guessing that’s what those little spring steel ears are for. Something with a built in arbor will come completely off and un-azz the area though, so I’d be careful with those. Would have saved me twisting the whole disk when one got stuck had I know that trick-feature before.

One other thing is check for accessories for whatever models you’re looking at. They have some useful add one like a loop top handle and vents that snap on over the fan ports to keep debris out, but they’re not available for all models. Might help you decide on which one you need more.

A cure for the dreaded hairy belly.

Mine have been great tools, my first one has been in service for at least 12 years, probably closer to 15 now that I think about it. The only issue I’ve had with it is the little lock tab on the front of the trigger that slips in the recess in the chassis, it’s prone to wear and has needed to be replaced. It will continue to function normally but won’t lock on.

I haven’t seen a decline in quality with my later Metabo stuff like some of the other big tool brands either. If they’ve cheapened stuff up it’s in a area I’ve not been able to notice.

LOL! Let me tell you a story and you’ll know why I’m laughing. Years ago working a shutdown beside another crew I saw something that surprised the heck out of me. Those guys all had Metabo grinders, which were new to me, and what surprised me was that when it came time to change out a grinding wheel they’d push the shaft lock button while the grinder was still spinning! The used up wheel would promptly unscrew itself from the grinder, and they’d have a new wheel on before the old one quit rolling across the ground. I thought man, this is going to hilarious when those things let go and the parts fly. So all that week I was expecting parts to fly any minute, but it never happened. I was sold. I thought any grinder that will take that kind of abuse has to be a very well made tool. When the job was over I went out and bought my first Metabo, still have that very same grinder today, very worn, battle scarred, and certainly no longer new, but still works.

All this time I thought those things were bulletproof but it was a case of me not understanding how they were engineered or designed to be used LOL! Thanks for the education, learned something new.

P.S. None of my Metabos have ever had the shaft lock pressed while the shaft was still rolling.
