The dcg has a rotatable head. Basically its designed to remove the 4 scews and rotate. Its great to have the ability to do this i have set mine up more so for cuttting..

Is either of them variable speed? I bought an Ingersol Rand air grinder that I mainly used as a polisher by putting a shaft extension and a buffing wheel on it. But if you are going to do something like that it will need to be a variable speed trigger.

I have both, the brushed model has a smaller grip and in my opinion holds better and for longer when cutting. The brushed model will last longer, but the trigger switch is a little weird to hold. Both were in the buy-one get something free from the big box store. The 5aH and 6aH batteries are the way to go.

Buying the kit saves some money on batteries if you are planning to buy more later anyway

I’ll get the newer on probably

I forgot to give you the model number of the milwaukee grinder 2888-20

While brushless is the latest, still the 412, has its qualities that the brushless doesnt have

I see one major difference between them.. The old one is proven as a great tool, if somthing stays in the linup for that many years its says it all.. Its brushed which means its internals are simple, cheap to repair and lasts years and years.. The new brushless stuff.. If you break it its going in the bin.. New tools are designed for short lives.. They just wont make them like they used to.. There too much money in being able to sell you a new tool rather than a few spare parts.. I stocked up on brushes for my circular saw and this same grinder, If it breaks I can fix it myself and see another 8 years or more use with it..

I wish dewalt re designed the 412 into brushless motor

Still can't beat electric
