Portable long-lasting power
Get the power to perform at your peak with the cordless Dremel 8240. With this portable powerhouse, you’re in control. You get the same power as with corded Dremel 4250, but without being tied to a socket. Small but mighty, you’ll enjoy a long runtime thanks to its powerful and removable 2Ah battery. So you can work where you like for as long as you like.
Designed with you in mind
Dremel 8240 is designed with you in mind. From the ergonomic tool design to the button placement, this portable multi-tool has it all. You’ll love our trademark Dremel look and feel, with its super easy set-up and logical layout. We’ve made it run cooler and with lower noise (compared to Dremel 8220) so you can focus all your attention on your project. Plus the soft grip fits you like a glove. The speed setting of the Dremel 8240 is in the middle, right where you place your thumb to hold the tool. Now that’s ergonomic design at your fingertips.
Dremel 8240 also has a motor-brake which enables you to be more in control and safe. Rather than applying a slowing force, motor-brake stops the rotation immediately when turning the tool off.
The LED battery life indicators show you at a glance the remaining battery charge level. Your Dremel 8240 includes a hanger bail so it’s easy to hang on your Dremel toolholder with your Dremel Flex-shaft.

Brushless Motor
Brushless Motor
Since brushless DC motors have no brushes to get worn out, they represent a huge leap forward in technology. Brushless motors have significantly higher efficiency and performance, and a lower susceptibility to mechanical wear than their brushed counterparts.The cost of a brushless DC motor is comparatively higher as compared to a brushed DC motor as it requires an electronic communicator, essentially a computer inside your cordless tool. This is what drives the cost of the brushless motor up.
