HILTI angle grinder quality???

Question

I've been looking around for some extra angle grinders so that I don't have to constantly switch between grinding disc, cutoff wheel, cup brush, etc--just grab and go.

I found a local guy who has some Hilti angle grinders for sale. The model number is DC 700-S and the Hilti link is here:

Can any one comment on the quality of these units? I am familiar with the Hilti rotohammers and their quality is second to none. I didn't realize that they even made angle grinders.

Thanks for any input.

^^^^^^^^^^^^^^^^I use the cheap-o angle grinders from Harbor Freight (under $20) to solvethe same problem. So far, I have not had one fail.BTW, HF has an accessory attachment which replaces the grinding disc with a1" rubber drive roller, and converts it to a belt sander.  Some call it apower file.  This works really well, and is tons cheaper than my Milwaukee(which I admit is better made.)

Hilti stuff is some of the best in the world.Right up there with Flex, Metabo, Fien, Trumpf and Hitachi, for quality.

They are top of the line. No brand anywhere is better and their price inEurope reflects that fact.Steve

I too have been using a HF angle grinder, around $18 on sale. (They sell several, some of which are a little too cheap even for me!) I HAVE had mine fail, twice ... the first time it was because the brushes needed to be replaced (awfully quickly, IMHO -- and they included spare brushes in the box. Hmmm...). The second time I couldn't figure out what was wrong for a while; finally narrowed it down to a bad power cord ... and then realized that somewhere along the way I had parked the still-spinning disc next to the cord and severed part of it. I guess I can't blame HF quality for that one!

Bottom line is, while the HF quality is not overwhelming, it works just fine for my hobbyist uses, and I would readily buy another. However, for large scale production work, which I'm thinking is what the original poster may be doing, I can see where it would be worth paying for the top quality!

I checked out that Hilti grinder last night and decided to pass on it. This is a 15.5A, 7" grinder that comes with a diamond cutting wheel and a thin abrasive "grinding" wheel that I would have called a cutoff wheel.

The no-load speed on the label turned out to 11,000rpm as opposed to the

8,500rpm listed on the Hilti site. This limits the wheels I could use considerably. I'm still looking for a grunty lower rpm grinder to keep a grinding disc or cup brush on and 11,000 rpm would be scary-fast. This Hilti looks to be more suitable for cutting stuff--including masonry.

Another thing I noticed was that the guard was a lot thinner metal than the one on my 6" Porter Cable (=FLEX) grinder.
