    I recently had to buy a new cordless drill as my old one had been slowly letting out the magic smoke for a couple years. I went with Bosh, same as the original, as it’d taken a significant beating and was still preforming, although smelly.

    While I was at Lowe’s buying it, I noticed they have a deal where if you buy the cordless angle grinder(non-bushless) bare tool, you also get a free 4A/hr battery and charger.

    My most used power tool is an angle grinder. second maybe to the drill press, but barely. Since I saw it, I’ve been thinking about getting one.

    My usage isn’t all that often. I can envision setting up my corded with a wire wheel and the cordless with a cutoff wheel and not having to change anything for a long while.

    Opinions on the cordless non-brushless cordless angle grinder?

    I own the 18v grinder. It works well. Battery life isn’t great. But does what I need it to do with a 4 or 6 amp battery.

    Do you think the Profactor line up will improve on this?

    I don't do a fast job. I don't do a slow job. I do a half fast job.

    Being brushless should help a little. But I feel grinders are going to be power hogs if you work them.

    Depends on what you are cutting and how much of it.

    My Bosch 4.5″ grinder, when paired with a fully charged 6.3ah core battery, will make ten partial cuts of 5/8″ rebars (enough to bend and snap it off) before the battery dies. So if you are looking at all day grinding or cutting you will be disappointed. I discussed this extensively in this thread:

    You get 3 minutes of grinding or cutting.

    I think that is what they are hoping. We’ll just have to wait for the tool testers to get one and put it through its paces. Most do a speed test which is important but testing the number of cuts is also important. To me the current cordless grinder is a more of a cutoff tool than an all day grinder.

    Yup same here , I used it for cutting tile , works good , but like you said , they demand lots of juice , I think a corded grinder is a must for heavier applications , just for an example , I used the cordless with a diamond blade , I think I cut around 15 to 20 linear feet of tile before I had to replace the 6.3 core battery
    And used the bosch corded with the diamond cup wheel hooked up to the dust extractor , and never had to deal with replacing batteries , like Ron said , it depends what you need to do with it

    I love it for quick jobs
