Most air impact wrenches use two independent hammers so there's one impact per rotation. Cordless impact drivers and wrenches use what I guess Hitachi is calling two anvils so there's two less powerful impacts per rotation. Now Hitachi has three so there's three even less powerful impacts per rotation? And decreased the RPM to compensate? At least that's what it looks like from the specs? 1832 in-lbs is on the high end of torque whereas 4000 BPM higher than anything else and 2900 RPM is down below most budget impact drivers. For comparison of specs Hitachi: 1832 in-lb, 2900 RPM, 4000 IPM Makita TD170: 1549 in-lb, 3,600 RPM, 3,800 IPM M18 Fuel: 1800 in-lb, 3000 RPM, 3700 IPM Dewalt DCF887: 1825 in-lb 3250 RPM, 3600 IPM Ridgid gen5x: 2,250 in-lb Ryobi: 1600 in-lb, 3200 RPM

They may have done some black magic in the driver circuit to allow it to run straight off rectified mains power, but otherwise 1080W (60A at 18V or 15A at 120V come out the same) from a supply requires a transformer around 100in3 which is a very expensive and heavy power brick. Basically if a motor needs power converted for it, the transformer needs to be around the size of the motor, unless of course it's the same voltage like Dewalt or the electronics use the motor itself for power conversion. tldr: Possible, not probable. That said I really want this.

I'm like you occasionally looking at other brand blades in hope something better will show up, but it almost never does and I haven't found a circular saw blade that will compete with diablo. Particularly if you run into unexpected* stuff in a cut the Diablo blades are the best especially for the price, and by a large margin if you buy a bunch on sale. *Who am I kidding we all say screw it and cut regardless of what's there by the end of the day.

I tend to focus a lot on keeping the working edges and handles in good condition but the other parts get beat to hell. I don't want rust on a blade or burrs on a handle, but the bottom of my battery packs look so bad I bet they'd be denied warranty.

I wish we had grocery stores like that in Canada's boots.

Thank god that's a joke otherwise our toys would be regulated by now. "Assault power tool ban" has a ring to it.

Thats awesome. Inb4 someone puts saw blades in with their laundry.

Usually there's a washer that goes over the blade and the bolt tightens down on that which gives more surface area to press against the blade and keep it tight and flat. Can you spin the blade freely by hand when it's tightened down?

If I had to guess they are factory incompatibpe but work with some modification to the battery or tool just like the current sbd lineups.

A dewalt fanboy picked up one of those when he was supposed to get a diablo blade because of that little 2X life vs diablo thing in the bottom left corner. I was surprised how good it was fresh, but it didn't hold up well.

Every grinder* is 5/8-11 and I've switched nuts between grinders when some idiot loses one. Plus I thought they said in the demo that the nut was compatible with most grinders. *I know there are some oddball grinders with strange arbor sizes but I don't know of any recent one.

They all make different models. You want one with a forced rotation mode for heavy sanding.

I recall the 18V dewalt did so the 20V should. It's not something that's advertised, just inherent from the easiest way to assemble the gearhouse of an angle grinder. I first discovered it by accident when I reassembled a Makita angle grinder the wrong way.

What's not to love about a grinder that can cut rebar with a 1/4" grinding wheel. https://www.instagram.com/p/BJCMqvyhFre/?hl=en

I think that works on almost every grinder or at least a lot of them. Usually it opens up the gearcase though so it's not something you want to do on a dusty jobsite (ie. the kind where you're using a grinder)

Not only does the Dewalt plug in, but you can get the flexvolt with the corded adapter for just $50 more than the DWS780 and go cordless sometime later if you need to. The M18 is top for cordless saws but the Dewalt is more in the class of corded saws.

Every reputable manufacturer I can think of makes a small, high rpm, low impact energy rotary hammer for small holes and softer materials. If it's hard enough that I can't use a twist bit, I want a rotary hammer.

14mm is a decent bit for such a compact drill meant for tight spaces The problem with compact hammer drills is the same as larger hammer drills just worse. If I could always have an SDS drill on hand and never tough a hammer drill again I'd be happier.

There are so many asterisks on that page I thought for a moment the Dewalt trademark was for 20V MAX* instead of 20V MAX. There are: ************************************ (36) total * ****************************** (30) point to a reference ******** (8) are doubled ****** (6) are the reference **** (4) point from one reference to another

The XDT14Z (TD154 elsewhere) is already listed on the US Makita site so that might be available soon whereas the TD170 could be a long time. I'm starting to think there's some regulatory agency that slows down Makita releases in the US because it's a big market to halfass.

There really isn't a disadvantage since it's a couple ounces on a >7lb tool and folds out of the way. It's a huge lifesaver when you're holding something in place with one hand and actually have the saw within reach.

The highest USB charging rate i know of is 3A at 5V so less than 1A at 18V and 2A ar "12V" which is really really slow for charging a power tool battery.

I'm guessing that senses the dust flowing which you couldn't do before the vac turns on. What is really necessary (and I'm surprised festool doesn't have this already) is a signal either sent through the shop vac hose or using bluetooth to the vac. The downside is this requires compatibility between the two tools which of course won't exist between brands. I bet Milwaukee will have a onekey vac in a couple years and re-release the miter saw so everyone who wants dust collection has to buy a new one.

You can get a halfway decent generator for that not to mention adding batteries onto it. Power conversion electronics rated for that kind of power or expensive but not $580 expensive.

The symposiun is really about the flashy products they want to get media coverage from (and not bad press like the nailers) sds max, miter saw, one key. They want to make people switch to milwaukee and not away from it for the upcoming stuff. Notice a lot of the things they announce dont hit the market for months or years.
