Batteries + corded tools
« on: March 14, 2017, 01:49 AM »
Why hasn't anyone come out with this? Yes it would cut their sales in half but the tool would be so much more useful

As in one tool that works corded and cordless? Probably not available due to massive differences in motors between the two.

There have been a few attempts .. but I'd rather have a too optimised, not compromised personally [smile]

     A long time ago I once had an electrician friend set up a small transformer connected to a gutted Dewalt battery pack for this purpose. The battery pack became the "plug" into the tool.  I mostly wanted it for a back up when using the cordless DW trim saw or just in case all packs were dead. It didn't really provide enough power (transformer too small) but it did work and was a pretty cool custom set up.

Corded tools are AC. Battery tools are DC. You'd need a converter which would be bulky.

But, I do think the Plug-It system is a great candidate for this type of solution and said as much when I worked at Festool.

Do you mean use a car battery and inverter with modified Plug-it cord?

Michael, I'd like to see it as a belt pack. You can slide one or more Festool battery packs onto the belt. It would also have the converter attached. A DC-power-enabled Plug-It cord would come out of the converter. It would be put on the left or right side of the belt depending on your dominant hand.

Hi,

Kress offers this as "BiPower" - Never worked with it though. But it is an interesting approach for sure!

Kind regards,

Or maybe like the Mirka CEROS, where the sander is a Brushless DC, but the power supply is external rather than inside the tool like their later DEROS.

Then all the tools would use a common battery, and the power supply converts to DC and has a male end that goes into the battery slot... but instead of terminating at a battery it heads off to a wall outlet.

Or one plugs in a battery in if there is no wall outlet, or they wish to not be leashed by a cord... Basically they have a choice whether to charge a battery from the wall, or power the tool from the wall.

My farther did this some 25 years ago. Was very useful in 800mah nicd days, probably much less so now.

Don't most handheld power tools use universal motors already?

Ryobi has this on a couple of their One + offerings. Portable fan, yard tools, etc.

Not sure...
(I have not seen an 18V 50-Hz nor 18V-60z battery to compare them.  [wink] )
But I think you are onto something.

The new DeWalt FlexVolt tool lineup offers an AC adapter that plugs into the battery slot and powers the tool from an AC outlet.


Its very "doable", companies just want you to double buy if they can get you to.
If at first you don't succeed, redefine success!

As Cochese said Ryobi offer this with some of their tools and I expect you'll see it appearing in more and more of their tools. Sounds like a great idea to me!
