I have a 4 1/2″ Hitachi grinder, which worked well, until some mdf trim gummed it all up. I guess I really should be using a disc sander, not a grider. But I can’t find a disc sander attachment for the hitachi grinder, so I’m thinking of getting a disc sander. Which one do y’all use, or recommend?

A good sander attachment is a Makita IIRC, I use a lot of HF cheapies, jus the rubber backer and discs.
As far a whole new unit, I'd lean towards Makita, but don't think I have seen a small one, just like 7" or so?
I'd really just look harder for the 4.5" or 4" discs, heck of a lot cheaper.

Are you using grinding wheels or sanding wheels?

It came with a grinding wheel. I want a sanding disc, but haven't found them for my grinder. Guess I'll check harbor freight. Just wondering what others are using.View Image “Good work costs much more than poor imitation or factory product†– Charles GreeneCaliforniaRemodelingContractor.com
Huck,I have a 4 /12" Hitachi grinder also. It has a 5/8" arbor, which is very common with this size grinder.I've found sanding discs and a backing plate for them at Home Depot.It works very well for coping. I usually use 80 or even 50 grit.If that is the same grinder I have it is an excellent tool.
Thanks, I went to the big box and picked up a sanding backer and some discs. It came with its own flange, and wouldn't you know it, none of my three wrenches are exactly the right size. But its easy to lock the spindle, and just tighten or loosen by hand, so no biggie. Looks like this will work great - thanks for the tip, and for saving me some $$! - HuckView Image “Good work costs much more than poor imitation or factory product†– Charles GreeneCaliforniaRemodelingContractor.com
If it is a pin type spanner HF has an adjustable one.

Did you look at the link I provided?

Yes, I did, thank you. I just wasn't sure I see the connection, since I was looking for sanding discs, and didn't find any there. Are you saying you use their products for coping trim? Which product specifically?View Image “Good work costs much more than poor imitation or factory product†– Charles GreeneCaliforniaRemodelingContractor.com
I can't say their products are for coping trim or not.
I thought your problem was mdf clogging up a grinding disc.
Those flap sanders are nothing more than a sanding disk that is layered.
I haven't used that brand, but have used flap sanding discs that are made to fit on a grinder to shape wood.
If you're looking for an adapter to put a pad on your grinder, check out sears, that's where I got a bunch of transition bushings to go from 3/8" to 5/8" on a couple of my grinders.

Yes. I was using it to cope trim, and the mdf clogged the grinding wheel. I should have been using a sanding disc. Since its a delicate operation, I don't think the layered sandpaper would work. But thank you for the link, and for your efforts.View Image “Good work costs much more than poor imitation or factory product†– Charles GreeneCaliforniaRemodelingContractor.com
Just put two sanding discs back to back in the grinder. The 50 and 80 grit discs are stiff and it gives you two surfaces to work from.

There ya go.
just remember the upside down one is spinning the other way, carving INTO the profile can cause a skip/jump and take off a layer of dermis, that you may want keep attached to keep the red stuff inside.Spheramid Enterprises Architectural Woodworks
