We need an 18 volt RO90....

[TheTrooper]

This would be a great addition. It would be used in spot finishing of doors, casing, crown and so on in new construction where dust collection isn't a priority but portability is.

 

[AlexThePalex]

It is a nice idea and I would love to have one, but I have yet to see a cordless sander that actually works.

 

[Mort]

I'm ALL about cordless tools, especially how battery and motor technology is advancing, but a cordless sander is a bit beyond even me.

 

[Kev]

You'd probably get one pass over a door frame ..

Ever tried a cordless polisher? ... DON'T !! [wink]

Bring on a small cordless Festool VAC though - I'd be up for that.

.. and the cordless multi tool

.. and the cordless Festool recipro

If you own any of the 18v Makita tools then their cordless Makita sander for the money is a good addition, especially coupled with a 5ah battery, comes in really handy for quick jobs.

 

[Holzhacker]

Considering how I use my RO90 I don't see cordless working out very well.

 

[ifit]

Yes ro90c for me too!

 

[TheTrooper]

I will look into the Makita. I have all festool and Dewalt  stuff but it's mainly for my uncle. He's a builder an constantly borrows my ro90 to sand filled nail holes that his guys miss. Blemishes in drywall and so on. For a 4000 square foot house it takes him about 2 hours, 60 is from screwing with a cord from room to room.
As for me, there's a few times where I have to make a threshold or something and it needs a quick 2 minutes of sanding . Now common sense not to use it for a whole staircase or refacing a kitchen full of cabinets, but for easing the edge of a board here and there it will be ideal. Plus the motor is small

Maybe not, but those 5.2ah Festool batteries are pretty fantastic at least so far.

Could we plug our corded tools into the cordless vacuum?  Hmm...

I can see a power back pack in your future ... or even a power vac back pack. Heck, tweak it a little an you could even have a power vac jet back pack and fly directly to you jobs [big grin]

 

[sancho57]

Kev why not a nuke one?

why not get the dewalt cordless multitool . I use it for sanding all the time. its not a sander you would use for a normal sized jiob but works great for a quick bit here and there

I have the cordless Makita sander. Game changer especially when up on scaffold. Still prefer the Festool stuff for the dust collection, but so easy to grab the Makita to sand base scarf joints, outside miters, etc.

 

[Shane Holland]

What we really need is a Plug-It-battery. Then any tool could be corded or cordless.  [wink]

 

[Mort]

Or, conversely, an adapter from your 18v battery slot to a plug-it lead, for when you run out of batteries on your cordless sander. Or anything else for that matter.

I can see how that's comfortable. But how long run time do you get out of a battery?

^Exactly^

A plug-it battery would need to output AC, and I do not recall a battery that does that.
In most ways DC is nice, one you get past Tesla generation and distribution.

And many new AC tools are using DC motors. The easiest way to envision it would be like a Mirka CEROS.
One should be able to have that powered by a battery as it is already an outboard DC supply.
But then we are back to a cord.

I am not sure what the fascination is with cordless.
There are also air powered tools, if cordless means no electricity.

 

[Shane Holland]

Right, no AC batteries. But I could envision making an inverter that's compact and lightweight enough to be worn as a belt clip to which you would attach the battery. While not completely untethered, I would be willing to compromise a cable running from my waist to be able to choose between corded/cordless. I'm no electrical engineer, so I'm not sure what the battery life would be like using an inverter.

[member=48572]Shane Holland[/member]  [member=46908]Mort[/member] I believe was suggesting that the tools be DC, and the you either use the battery, or a DC supply that comes from the wall and plugs into the battery's slot.

That would be elegant.
