I have the same set up. The Milwaukee is a tank. I drill a lot of dirt holes with mine with a 2" auger and put a 3" auger on for gardening when I'm transplanting new plants.

It's a 20 volt 1/2 inch

I bought 2 rigid because of the warranty. They burnt up in 50 holes. I went back to Milwaukee 18 v. I did a test run on the rigid with a 4" auger planting 270 trees in April. 20 holes on 1 rigid, 30 on the other. finished the rest with my Milwaukee and its still going. You get what you pay for, and you don't want to be down while in the middle of know where.

Exactly why I'm asking you that have experience with these drills running Augers! Which model milwaukee exactly are you using Please? Wgen i do pull the trigger im going to buy 2

Same set up for me.

I had an older 18v Milwaukee hammer drill that gave out on me the first year I used it with a 2” auger.

I bought a Hercules 20v from Harbor Freight, it comes with a 3 year on tool and 5 year warranty on the battery. That may be swapped.

I had the drill strip the gears after the first year, took in and they handed me a new one. It is still going strong the past 2 years.

Drill, charger and 5 AH battery was around $100

I bit the bullet and bought the Milwaukee hole hawg 18volt last year and it works great. But I have a bunch of Milwaukee batteries. The one at harbor freight looks like a solid unit for the price if you aren't invested in a battery platform

The drills you fellas are talking about are useless in hard ground. Those drills are meant for drilling screws into 2x4's or hammer drilling a 1/8" hole in brick for a screw

You need an SDS hammer drill like this https://www.milwaukeetool.com/products/details/m18-fuel-1-sds-plus-rotary-hammer-kit/2912-22

Then get you an auger from Tom Stalker with the SDS chuck welded on it so you can directly plug and play into your hammer drill. No adapter needed
