    I seriously doubt that, take drywall routers for instance, as opposed to a gun they are exposed to evil gypsum dust which well destroys brushless motors. Some conditions just don't play nice with a BL tool so a 4 pole brushed motor is the better route. Brushed motors have come along way and although they have their limitation they are pretty durable all things considered. 

    Just curious, how does gypsum dust destroy brushless motors?

    Found something new online. Hitachi Presented a multi voltage battery in Japan much like the flexvolt.

     

    Can be either a 18v/5amp battery or a 36v/2.5 amps.

     

    A new impact driver and circular to benefit from the multivolt batteries in 36v modus.

     

    Seems they are completly compatible with everything.

    The new tools include:

    An impact driver that has 10%+ driving speed and longer run time compared to the the 18v Triple Hammer impact(with 6ah battery)

    A 6.5" circular saw with twice the cutting speed of their 18v brushless circular saw.

    4" and 5" variable speed grinders with nearly twice the power of their 18v brushless grinders.

    A 6.5" sliding mitre saw.

     

    More about the first multivolt tools here:

    @dmz2084 Are you including models with different color options and is it all brushless impact drivers worldwide or all brushless impact drivers from one particular country? Are you taking into account different model number between countries for the same impact?

    Different colour options count as the same model (Most colour options are for the Japanese domestic market and only available outside of Japan via grey import). US and World wide model name count as the same model, eg. for Hammer drills XPH07 and DHP481 are the same model. Also when the letter L was removed from the naming scheme  (eg for Hammer Drills LXPH01 and XPH01) count as the same model.

    Which brands hold the top 3 positions for the longest stroke length in 18V reciprocating saws? Tip: 2 are brushless, 1 is brushed. 

    All 32mm (1.25")  stroke. Brushless: Makita and Bosch, Brushed: Makita.

    Where do you have to be for 30 to be greater than 90? On the same point the anvil, spring and hammer in most impact wrenches aren't made from the same stuff impact sockets are yet they take the beating just fine. It would be the case that impact sockets can cost three/four times that of a cheap-o-nasty chrome socket. 

     

    As for prove me wrong, I don't see how. I've shown a data sheet which suggests impact sockets are harder than S2/Chrome sockets. I use impact wrenches all day every day and use both chrome and impact rated sockets; both do a job and do it well with the DTW281. 

     

    But back to the point I was originally trying to make before it got derailed, if you consider there to be a massive benefit to spending the/four times what you would on a normal bit or socket, spend it, it's your money. I personally haven't found that benefit after spending the money. 

    Those hardness values cannot be directly compared because they are on different Rockwell scales. The 90 was measured on the Rockwell B scale and the 30 on the Rockwell C scale with the C scale being harder scale, with some over lap in hardness on the high end of B scale and the low end of the C scale.

    I'm not anticipating 4000 mAh 20700 cells for a while; Bosch and Dewalt are just using 20700 cells in their high end batteries; are the Festool Airstreams? Milwaukee is still on 18650, as is Makita, and the last attempt Milwaukee made to leap frog the competition took a year and a half to hit the market. Moral of the story is I'm trying to enjoy having the latest and greatest with the 3.0/9.0 FlexVolt batteries and M18 HD9.0 lol. 

    Metabo have 3500 mAh cells coming. The Festool Airstreams have Sony 18650 cells same as Makita 6.0Ah. Makita are rumoured to have a 9.0 Ah coming. One problem for Makita with 20700 cells is that they make the battery pack too wide to fit the 18V X2 tools.

    6.5 doesn't cut deep enough. Seems Makita has magic brushes though. Their cheap old planer outdoes Dewalt and Milwaukee from what I've read. Didn't rob have that suspect test with the Surge though? ?

     

    Edit; off topic; thanks for mentioning that review @JimboS1ice, it's an interesting video. Testing is thoughtfully laid out and they award different wins for a ton of different aspects of the saws which is great. Also happy to see 6.5 blade lefts and 7.25 blade rights are separate classes. Makes me want to buy another blade left ? He dings the Makita hard for being dual battery, dings the FlexVolt for being a new battery, while admitting it's the most powerful saw, and narrowly awards the 2731 the win because of battery compatibility, yet all the testing is done strictly off the 9.0. ? Makes you wonder. I do love that saw though lol. Sucks that the new rear handle Makita will have the same asterisks next to its "wins" (but two batteries!). Drill tool fights are so much more straight forward lol.

    Yes that 18v makita smashes all the competition but you would expect that from a company that made the first electric planer I believe 

    The Dewalt planer is a bit stronger especially with Flexvolt or xr 6.0 batteries but the Makita is impressive considering it came out over 5 years old ago.

    Don't forget the different SKUs for colour as well ? 

    That's a Japanese only thing unless you import them. Hitachi and even Panasonic have different colours in Japan too.

    No, my thought was more for general purpose fastening especially in hard wood where the screw bit tends to cam out of the screw head(especially Philip's head screws). My idea was that a properly timed downward strike with the rotational impact would avoid this, but I have countless bad ideas that have gone nowhere:)

    Cordless impacts actually have a hammering effect due to their hammer and anvil design. This actually makes cam out worse especially with Phillips.

    its slightly smaller than the bs 18 quick, the quick has hammer function and has more power and it has a fine tuned trigger function, you can also change out the chuck, compared to the price of the makita kit the metabo has a premium price. The Drill alone is close to 200$ and and is not brushless, The SB 18 LT BL Q isn't available in america yet so you have to get it from europe and that commands a high price, close to 300$ w/ shipping. The SB 18 LT BL is slightly bigger but has more power as well and is brushless and as of now there is no sub/compact brushless version of an impact driver available (IIRC). All in all the makita is a better choice as its cheaper than its metabo counterpart, though I don't see the need for a sub compact 18v kit where there are 12v or 10.8v kits that can do the job these can.

    The bs 18 quick is non hammer.

    Knowing Dewalt, none of the accessory chargers will fast charge either...likely to only be the single that has this feature. 

    The DCB1800 Portable Power Station also only charges at 2 amps in each of the 4 ports which is pretty crappy.

     

  12. There's a bunch of different combo kits in Australia now that contain both the DHP481 and DTD148 including some 2 piece kits, but for along time the DTD148 wasn't available in any combo kits only lower end impacts were. I think the reason is because Makita had a large of inventory of impacts as they have produced at least 5 different brushless models that have been released world wide and they have a new brush model available in Japan.
