MikeyB Posted September 15, 2015 Report Share Posted September 15, 2015 Anyone know if an 18v cordless router is in our near future? Bishop have you heard any buzz? Quote Link to comment Share on other sites More sharing options...
Hugh Jass Posted September 16, 2015 Report Share Posted September 16, 2015 This is that one tool that I don't think we'll see short of mini fission reactors. It will either have horrible runtime or very little torque. Cool in theory but don't think it would execute well in battery format. Quote Link to comment Share on other sites More sharing options...
DR99 Posted September 16, 2015 Report Share Posted September 16, 2015 It might be possible now with brushless motors and 9ah battery pack like Milwaukee is planning on offering. I think that would be enough juice to do some serious work. Quote Link to comment Share on other sites More sharing options...
Andrull Posted September 16, 2015 Report Share Posted September 16, 2015 I too belive it would be possible to make. At least in the small range, to trim edges and stuff. Problem is not torque, but power (watt's). It is battery-power's weakest point. Brushless DC motors can exert a lot of torque, and use this fact to weigh up for the usually lower wattage (power). Thats probably why you rarely see producers that print or specify the power of the motor. Only torque in some cases. AC / universal motors on AC can easily and relativly cheaply be scaled up to a larger motor. They have (to a point) not the same current restrictions, and doesn't have to care about weight in the same maner (becouse it doesn't have to get a larger battery pack that weighs it down). And since a router is essensially just a huge motor with a router bit in the end, there is very little places that a battery can be placed without an awkward placement, and few other areas to shave of more weight, except the motor. And since routers doesn't need need the high torque advantage. They need a combination of mediocre torque and fairly high RPM. In other words, just a lot of watts. The highest specified motor power output in drill's is in the range of 650W, which is fairly close to a small trim router. Would be close or equal to a AC-motor with around 1000W input power. And to make matters worse, the load is almost constant in that kind of work. Not short runs and short breaks in between, which mean it's gonna drain the battery quick as hell. Just like a battery-operated vacuum.An 5 Ah 18V battery would probably be drained in practically 5-6 minuttes. Given the high power needed. 1 Quote Link to comment Share on other sites More sharing options...
Martini Posted September 16, 2015 Report Share Posted September 16, 2015 Maybe you don't need to have the battery on the tool. Quote Link to comment Share on other sites More sharing options...
optimistspencer Posted September 16, 2015 Report Share Posted September 16, 2015 Actually, the bd matrix/craftsman Bolton has a trim router attachment- never used it tho so I don't know the runtime/power.Sent from my One M8 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Andrull Posted September 16, 2015 Report Share Posted September 16, 2015 Look at that. At least the battery placement wasn't awkward. Lol. not. Quote Link to comment Share on other sites More sharing options...
Marcv76 Posted September 21, 2015 Report Share Posted September 21, 2015 Ryobi has one. I have it and like to use it for quick rounders. It works perfect. Im sure a more professional tool company could make an even better one. http://www.homedepot.com/p/Ryobi-18-Volt-ONE-Trim-Router-Tool-Only-P600/100342147 Quote Link to comment Share on other sites More sharing options...
Bigmikez Posted September 21, 2015 Report Share Posted September 21, 2015 Wow it even had a good star rating I would've never thought ryobi had one. Quote Link to comment Share on other sites More sharing options...
