    Not sure why you’d use a drill of any kind for some of the applications that are being mentioned. Such as the trap on a furnace.

    I always use an impact for driving sheetmetal screws, or framing type wood work as well.

    You need to have a feel for the tools you use.

    As far as banning an impact from the service department, thats silly. Ban stupidity, or go all the way and ban all power drills, and issue nut drivers, sockets, and egg beater drills, or bit braces. Things will only take 10 times as long.

    Note that I do not run a service department...

    Agree that banning a tool is kinda silly...

    How about having training classes... teach folks how to use the impact properly... and have a refresher class once a month...
    Better yet... schedule regular training classes that include refresher classes... better trained techs make the company more $$$...

    I have one employee who will not stop using his impact driver in my equipment. Has pretty much stripped out all of the sheet metal on RTU's. Even on brand new NEMA3 box covers..... Plus, in a casino environment they are quite distracting to use indoors. Impacts might have a place, but it is not when you need something with a bit of finesse and low noise levels!

    Again, thats a problem with the operator, not the tool. Everything has a throttle so to speak.

    I bet this guy chirps tires after every stop in his car. Some people dont understand that a foot pedal is not only 2 positions.

    You cant fix stupid. Fire him.

    Lol, I love your idea of a quiet atmosphere. For instance every time I have a nice book I want to read I always head over to my local casino and find a quiet table to sit at. I usually find one right next to the slot machines.

    I don't dissagree that the guys that do it are to blame.
    But....
    Impacts will tear up screw holes. We've been dealing with it for years. Threats, write ups, warnings in service meetings, etc. Holes get stripped far too often. Until we said no more. At the same time I made the rule we aren't to use impacts to pull panels, I also increased the tool allowance $200 a year to cover the cost of having to buy something new. And they aren't banned from use for everything. Just securing panels back on units.

    You walk up on a 3 year old unit and it's got three sets of screw holes in every location because new ones need to be made.

    You may think it's stupid, but standard drills with clutches and the hex screwdriver with a clutch I listed above work better as overall tool and are gentle on panels.

    I do agree though that it can be done correctly with an impact, but I can't be on every roof standing over the shoulder of every guy. The problem is we are a large company. If there were 4 or 5 guys working service, I could better control stupidity like misuse of impacts on panels.

    I have the skill to use a M12 impact on panels and not damage them. But I prefer the hex screwdriver. It's actually a better tool for pulling and securing panels. I wouldn't use it if it weren't.

    So long as impacts are still available, then having a do not use for this task sort of policy is fine I guess.

    Yeah... there is the 'people management' part...

    We are a small shop (one man show with install crews, maybe a full time helper next year)...
    We keep close reigns on the install work, and I am usually the one doing service (with my helper running back and forth to the van). For now... I prefer the M12 impact.

    While we are on the subject of the M12 impact...
    I see there is a NEW Milwaukee M12 impact... called the:

    M12 SURGE (FUEL) impact...
    Has a hydraulic drive, so it is quieter...

    Has anyone tried it yet???

    Some of the guys at work have the surge. Ive played around with it and it was a little quieter Id say. Like it didnt hit as hard. But it did seem to drive screws faster. A little heavy in the hand compared to my Bosch and definitely bigger.

    I think thats the one I have. I just recently bought a new combo impact/drill and the impact looks just like the one that comes up when I do a search for m12 surge.

    The previous m12 impact and drill are now on home renovation duty.

    It has 3 settings I think. I just use full throttle. And manually adjust the speed by adjusting my trigger finger.

    I use an impact for pretty much everything I do. Unless Im drilling with a unibit or masonry holes. Ive got a 12v Milwaukee fuel and an 18v makita. I dont understand why its so hard for some people to modulate those things. The triggers are variable speed with the lowest being a mere crawl. I guess some people just lack any kind of finesse. I feel sorry for their wives/girlfriends 😁

    Yeah...

    IMO it is really not hard to learn to 'feather' the trigger of a 12V impact...

    But then... if one of your techs is a good guy, but will not learn...
    Guess the thing to do...
    Is to get him a drill driver with a torque clutch...

    I need a replacement 12V FUEL drill... mine seems to have a bad motor (weak)...
    May get a combo kit with both...
    OTOH... I have half a dozen M12 batteries, they all seem to be good...

    THX for the input on the SURGE impacts...

    I use a hand nut driver to remove/install panel screws.... and I carry boxes of number 12 and 14 screws around to fix the screw holes that have been wallered out by drills and impacts.

    Dont use a gd impact on anything that has to be removed again.... Ive seen guys ruin blower housings before using them to put the screws back in to the motor mounts..... how freaking lazy can you be...
