Nice to see them expand the series. No use for one now but I do enjoy the 1/2 impact and drill. Still have the W7150 that's 10 years old now, and now the newer W7152.

I have the W7152 and was wondering if you use it for tires? I have used it on 1/2 power with a 65 ftlb torque stick and it still puts the wheels on too tight.

This ship has sailed. Everybody already has either a Milwaukee, Makita, Metabo or DeWalt Cordless grinder by now. Day late and a dollar short.

I work in an industrial setting for over 10 years and I don’t think I’ve ever seen a IR battery powered tool in the wild. I’ve seen countless Milwaukee, Makita, or Dewalt. Could be something to do with the location or industry I’m in though?

Torque sticks do not work well with the mechanism used in cordless impacts.

Speak for yourself, but I'm not a fanboy of those Home Depot brands. I prefer the industrial grade tools like IR.

I had a W7150 and I wouldn't say it was any more heavy duty, then my Milwaukee 2767. Well they are Home Depot brands as you say, you can get them through many other channels(MRO/Tool Trucks/Local Hardware stores). I think that is what makes the fanboy tools more popular, along with the wide portfolio of other tools that works with the platforms. I would say I see most trades using Milwaukee locals. Commercial plumbing/construction/electrical contractors that I have had in for work at the plant I work at all have used Milwaukee exclusively.

When I drive by a construction site, I see IR compressors and jack hammers exclusively. Don't recall ever seeing a Milwaukee brand of those before. That's pretty much what sold me on IR air tools 20+ years ago and that transitioned to cordless some 10 year ago.

Yeah IR is a big player when it comes to pneumatic stuff for sure but their cordless tools are far less common.

Torque Test Channel did an excellent video describing this issue. Torque sticks with air impacts work fine. Cordless not well at all. The reason is the rate of impacts. With air it's slower and gives the torque stick time to relax between blows, with cordless the impacts are so rapid that the spring (torque stick) can't relax thus the over torque problem.

Amazon has a $150 off offer on this when you apply for the Amazon AMEX business card. Not sure if this promo is available to everyone, but I just ordered the tool for only $50.

I had the old Ingersoll rand cordless stuff years ago. Loved then all. Had the 14.4 volt stuff for at least ten years before the batteries went to ****. The cordless die grinder was by far my favorite tool of all. The first one lasted me 5 years or so, with some heavy use! The second one lasted until the batteries wouldn't keep up with it. The tool itself was still good. The batteries just wouldn't run it for very long anymore. The drill and 3/8 impact ran till both batteries I had wouldn't run them anymore. The batteries were very hard to find for the old platform so I went to Milwaukee. Same with the Ingersoll 20 volt impact, it was great for about 5 years, then the Batts took a ****. It was cheaper to switch to milwaukee than buy two new batteries. I will say the milwaukee has more **** behind it than the Ingersoll did as well.

And where the hell are you going to get an I-R battery on a weekend when invariably your battery ****'s the bed. I'd rather just roll into HD or Ace and buy a Milwaukee battery on the spot than wait for a special ordered I-R battery for a week or two.

Batteries don't just **** the bed, they degrade over time so you have ample notice they are getting weaker. And I would assume you have two of the same battery anyway in case one runs down. Plus you can get knock-off batteries for a fraction of the price. https://www.ebay.com/itm/274982944059? A pair of Milwaukee batteries at HD are $250! Holy ****, that's more than a pair of car batteries! https://www.homedepot.com/p/Milwauk...-0Ah-Battery-Pack-2-Pack-48-11-1862/305082200

Did you bother to check the price of an IR battery? One 5.0ah battery at grainger cost more then that double pack of Milwaukee 6.0ah batteries at HD. https://www.grainger.com/product/48KT06?gucid=N:N:FPL:Free:GGL:CSM-1946:tew63h3:20501231

Modern batteries can and do **** the bed when the bms fails. I’ve had this happen on Milwaukee and ryobi, seen it happen to a co-workers dewalt.

I’m not even going to mention my experiences with aftermarket batteries, tried them all, from power tools to go-pros.

That was kinda my point. "fanboy tools from home depot" are easier to warranty/get replacements/expand the lineup due to so many places selling these various brands.

To the OP, that is great that IR is expanding the line of tools that you are invested or think are superior. I think it is a struggle to say they are more industrial then the offering of the fanboy tools as you call them. I think the biggest things they have against them is difficult to obtain and limited product line. Also I would say there 3/8 impact is larger then most others.

I've often wondered why some company that has a strong tool reputation that certain market segments are willing to pay a premium for doesn't develop cordless options that work with existing manufacturer's batteries. It would be so nice to separate the tool from the battery platform and go back to buying tools from specific manufacturers based on their strength with that type of tool vs just buying whatever platform you're using. I bought a Skilsaw cordless worm drive because I simply love that tool and there aren't really any other true worm drives that are cordless. But I can't deny it's a pain having to worry about a different battery for that one tool- would be much nicer if it was an option to use a couple 18V Makita batteries, or even a 40V XGT. Yes there are technical challenges, but you can buy adapters on ebay or Amazon to use batteries across platforms and people seem to have good results, so at some level it's doable.

I know people will probably say that being locked in is exactly what the big cordless manufacturers want and they will fight it with patents, etc. and that's probably true. However, I have always been under the impression that selling batteries is where the money is, so expanding the market of tools that can use your batteries would seem to be a business strategy worth considering.

There are plenty of specialty tool companies that don’t bather coming up with their own battery platforms, and simply use another companies platform.
One issue though, is that these specialty manufacturers are sometimes forced to switch between manufacturers for different tools, or different models over time, if they can’t get motors or parts from the former manufacturer they used, or if that manufacturer does not make a suitable motor for an application.
I mention motors, because the manufacturers who use other companies battery systems also are usually not motor manufacturers, and rely on motors from other manufacturers as well.

Trumpf and Draco are two German manufacturers of sheet metal nibblers and shears.
Both used to use motors and battery systems made by AEG/Milwaukee.
I’m not sure whether they still do.

Mafell, a very high end manufacturer of woodworking tools, has used motors and batteries from AEG/Milwaukee, Bosch, Metabo, and I forget who else.

Lamello, the high end Swiss manufacturer of biscuit joiners and other specialty woodworking tools has used Metabo for batteries for various cordless models over the years.

I’m fairly certain Dewalt used to supply motors and batteries to other manufacturers, and nay still.

Metabo actually now gas something called the “Cordless Alliance System” were metabo batteries can be used with cordless tools from a bunch of different specialty manufacturers, including Eisenblatter, haaga, Collomix, Mafell, Eibenstock, Starmix, Steinel, and Rothenberger.
