We have a couple large jobs coming up that will involve gluing engineered wood to concrete. We have done a few of these over the years, but in our area most of what we do is nail down.. I'm looking into buying a small hand held grinder with dust containment and wondering if anyone has any recommendations for any brands/models to consider?

Also, I believe they make grinding wheels for the Lagler Trio.. Wondering if anyone has experience with these? I hate to put my machine through this type of abuse, but we would likely use it for this very rarely.. Also, any idea who might sell the grinding wheels for the trio?

Thanks in advance.

I use a 7" grinder with a double row diamond cup or a profile wheel depending if I'm taking down high spots or just profiling to a csp-2 or csp-3. Its hooked up to my Dustless Technologies vac that has a pre-filter bag and two other cloth filters along with their dust cover for the grinder.

Thanks a lot for the reply. That seems to be exactly what I need. Did you buy this as a kit or do you need to it all separately? Would you mind sharing links of the different parts if you bought it separately? I just want to be sure I'm getting the right stuff.. Thanks again for the help!!

I found these.. This seems to be almost exactly what you have.. The prices for those dust shrouds seem to be all over the place, so hoping you can chime in and let me know if this seems to be about what these should cost?

Also, their is a bunch of different types of wheels and I'm sure this is for all different uses.. So could you maybe recommend a wheel that would be ideal for my first one that is sort of universal for concrete grinding and prep?

Thanks again for your help!

Yeah thats the Dewalt grinder I have. I think DeWalts shroud is to pricey. Plus, I like this dustless technologies one with the brushes around the bottom which allows you to go over uneven surfaces without dust escaping like the solid plastic ones to. I've used plenty of shrouds and this is the best. Plus it comes with the hose.
Just bought a new one two weeks ago. The old one lasted 5 years before the brushes fell out. It still functions but dust escapes more sinc e the brushes fell out.

I do like DeWalts double row diamond cup, has the most meat on it; for agressive grinding down of high spots.

Then I have the 7" turbo cup wheel like this one for simple profiling to accept adhesives to slabs, better grab. Some wood guys will just use their buffer with 24 grit to scuff the slab.

And finally I have this attachment for taking down adhesive residues. Works fantastic as the blades won't gum up. It also profiles the concrete at the same time.

Oh, my vac is the 16 gallon one at bottom left of the page. Has three filters including the cloth pre-filter bag that goes in the bottom part. Much much better than a regular vac system. And Made in USA if you c an believe it.

Man thanks a lot for all of the help. I really appreciate it. I think this is the exact set up I'm gonna go with. It probably won't see a ton of use because we do mostly nail downs, but when we do need it I'm sure it will make this super easy.. Again, I really appreciate the help.

Your welcome. I use mine on almost every job, some have lots of tile thinset, some just small high spots.

1) I am using an Edco 22" diamond blade grinder however it only grinds up to about 3" away from the wall. What do I need to use to grind the concrete up to the wall?
concrete grinding brisbane
2) The floor I am grinding was sealed many years ago and I am prepping for installing an epoxy primer. How much grinding do I need to do? Looking at the pictures below, is an occasional swirl still showing OK, or does it need to be perfectly ground!
