    CORDLESS ALL THE WAY, July 13, 2013

    Verified Purchase(What’s this?)
    This review is from: Dewalt DCG412B 20V MAX* Lithium Ion 4-1/2″ grinder (Tool Only) (Tools & Home Improvement)
    what you will hold in your hand is a grinder that is nothing short of the power it delivers comparing it to a corded tool.

    It spins @6800rpm; a bit slower than corded tool but it does not make much of a difference.(actually on some applications it is preferable a bit slower)

    it cuts, grinds,brushes through and on materials without mercy with pressure applied and no signs of slacking down….- for about 15 to 20 min. then the battery gives up on you…( hey- its a cordless tool)

    i think for 90% of all the work you perform with angle grinders it will give you the freedom not to to have look for a plug, find an extension cord, get tangled up in all your mess and find out at the end that you still short one foot to reach your workpiece. (sounds familiar)

    it will help to keep your blood pressure down.

    but if your work requires an extended usage … stretch out the cord.

    unless you are like me(hardheaded/stubborn) and insist on to use this tool going all the way through (same for the hammer drill, saw) a third battery pack is needed (talking about the 20V-3.0amp) since it takes longer to charge the battery than what you have on running time available.[update 1.13.15 with the 5amp battery’s it’s not even a issue worth mentioning it]

    my short wishlist of improvements is a BELT CLIP (i’m missing it on my hammer drill since it is not supplied with it and i don’t want to spend 10 bucks extra 🙁 ) and variable speed or at least three settings. this would open this tool for a far wider range of applications.


    i’ve been using this thing now for over a year on regular base. like every few days.

    i only can add that in regards to the quality of tools dewalt tops the list. still going strong this thing.

    We’ve 6 of these and they all work great. Not a hint of a problem in 1 1/2 year of use in the shop.

    These have the most torque of any of the rechargeable grinders we use….but with torque comes less battery life..

    In some instances (zip cutting) the Bosch with less torque but better a battery is fits the job better.

    The Bosch (2nd best) then Millwaukee and last is the Makita. The Makita grinder has clutch is suppose to keep the grinder from over loading but all it really does is keep you from working.

    Personally I accept that Makita and Milwaukee are good drills. But personally I love Dewalt and rigid!

    Remember that there are no internet regulations or police to insure that these comparisons are accurate or even fair and that anyone could be on the take and there isn't anything you could do about outside of running your own tests. So I purchased two favorites, charged their batteries and start boring holes in a scrap 4×4 with new drills. I did this and found the only difference was that when the DeWalt began to die before the Milwaukee it still had more torque. So the trade off was in the gearing, and I would take torque over horsepower any day.

    The biggest pain in the ass of most drills is the revese switch,
    it needs to go on top out of the way of my bear paw hands…….
