    There are always Forstner bits that one can use for a lot of situations instead of hole saws.

    The bigger ones need a lot of downward pressure though, as you get up in size it also becomes impractical outside of a drill press.

    True but Forstener bits in the larger sizes are expensive.

    True. I actually just got a RA drill that I could use with the bigger ones.

    Forstener bits on the drill press are usually the way I use mine.

    And you have to be careful how you use the bigger ones when not in a drillpress. They jam, they can wrench you and your drill around pretty good.

    That’s what the Bosch anti kick back feature is for.

    On what drill(s) does Bosch have that? I’m not familiar with that feature.

    Yes that’s the one, HDH181, I just got it a couple of months ago, haven’t tried to see how it works yet.

    Hold it in your hand and pull the trigger, now twist your wrist really quick and the drill will stop and LED blinking. 😀

    A trick I found that works good for getting plugs out, drive 2 drywall screws into the plug on opposite sides of the center bit, leave them sticking out. Then use those screws as a “handle” and twist it out.

    I may have to try this, thanks.

    this makes tons of sense, i’ll have to give this a go.

    Only two I know are the DDH181X and HDH181X brute tough model. Newer ones only, the older ones without X in model name don’t.

    I have neither. Just a model production 2003 of the DDH181. Shucks, now I need another drill? 😉

    I did find an article about this technology here…

    http://toolguyd.com/bosch-18v-drills-ddh181x-hdh181x/

    They are both currently on the prize list. I may be inclined to get the HDH181X as I have no smallish hammer capable drills in my arsenal.

    https://www.boschtools.com/us/en/boschtools-ocs/hammer-drills-hdh181xbl-55437-p/

    Wonder if this technology will be available in some future brushless models at some point. Not that it really matters to me. Brushed tools, don’t bother me.

    Whoever brought up this Active Response Technology in this thread, ‘Thank you’. I was not aware of it up til now.
