Concrete Grinders

[Rob Z]

Does any one have a concrete grinder, or have used one like this one by Makita?



Makita USA - Tool Details - PC5000C


Bosch makes one that is similar in size and price. (about $400 US)

Hilti has one that is about 4+X the price (aobut $1800 US), but the Hilti rep won't commit to anything :mad2:when I ask him questions about the tool, and I am not going to spend that much money on a tool that I can't either use first or get some good answers from someone that has used it.

DG 150 Diamond Grinder System w/ Power Conditioner: Item No.: 00369388 - Hilti USA

I want to use the tool for standard concrete prep for tile-remove paint, coatings, stains, blackjack, etc. I don't need to do large, commerical-sized preparations because we only do residential.

Thanks for any advice from the forum.

Hi Dave, I didn't think to check Milwaukee. Let me take a look...

Milwaukee has really dumbed-down a lot of their tools and sent them off to China to be made:incazzato: . I have a lot of old Milwaukees made in the US, great tools, still running well. The Chin-waukee stuff that I have bought is pretty much disposable.

The makitas I have are made here in the US, a lot of the Bosch stuff I ahve is made in either Germany or the UK.

Just had a little stroll round Makitas US site... How the hell does a portable band saw work! and why have I never seen one before?

Hi Rob, The plumbers buy those things on big production jobs. They cut pipe a bit better than using the sawzall.

I was :lol: at the mention of the "skyhook"** in the features section.

***A common joke on newbies on the jobsite. Is it the same in the UK? :smilewinkgrin:

No we really do use them in the UK, although fitting does require some specialist tools, namely a left handed screwdriver and a long weight:smilewinkgrin:

I have used concrete grinders in the past but not the hand held type on the site in the first post. I have usually used a carborundum block sander for light prep work and to take off minor high spots. For heavier duty stuff I have used a rotary floor grinder either with heavy carborundum disks or even diamond disks. For paint removal I would have thought a copper disk sander would deal with this
