    I seem to be pushing the RHH181 to the limits recently.

    Here’ s a hole using the 13″ extension and 2 9/16″ speedcore bit. The poured wall and solid stone are a combined 13″ thick.

    Cordless tools have come a long way, eh?

    Wow. Did it go through the batteries fast, did you start with a fully charged battery, and how long would you say it could last.

    Wow, that is pretty impressive. How long did it take to drill a hole like that?

    Never mind, guess we were typing at the same time 🙂

    Thanks for the tag anyhow! This is some great stuff. Putting the RHH181 to the test.

    Yeah, it’s going to take a battery or two for this application;)

    I started with 4 batteries. A 5.0, 4.0, and two 2.6s. I drilled for a bit, then swapped out for another etc. through all four. Then repeated that pattern until the batteries were all drained. That made it a little easier on them and kept them a little cooler.

    I went through that cycle twice. So two full charges for all four of them. Still not bad.

    Good strategy on swapping batteries to keep them cool. How long would you estimate it took to go through the 13″?

    I am really curious how long it took to go through all that, compared to say a corded one.

    Yes you are right good strategy, they hate being overheated.



    @RyanF
    what was the whole for, I dont recall reading, some type of wire housing,

    Oh, it took several batteries?

    The hole is for 1 1/2″ conduit from a new subpanel mounted out of the picture above it.

    Hard to say how long the actual drilling process was. I’d guess it was in the neighborhood of 4-5 minutes per inch.

    Really impressive for a cordless to drill through 13″ of cement and stone.

    Thats still pretty slow. It’s great that the drill Can do it, but your time would have been better spent using a larger drill.

    This is where a coring machine comes in handy.

    You pushed it through 4 batteries? Dang that’s impressive. Did you cool the bit during drilling, or took breaks?

    How long you took for drilling that hole ?

    did the drill feel hot after you were done? did it slow down during drilling?

    That is a pretty impressive hole for a cordless. I never would have thought to swap the packs out and rotate through them until they needed charged. I probably would have just gone until it slowed way down, but what you did makes perfect sense.
