Bosch 12V Cordless Edge Router Design
Brushless Motor
If you’re going to make a cordless router, especially on the 12V platform, you have to take advantage of a brushless motor. Bosch checks that box.
Physical Traits
Designing a cordless router like the Bosch 12V Cordless Edge Router begins with the question of how to position the battery and motor. With 18V systems, sliding the pack on top of the router is the best bet. 12V isn’t much different, but with a stick pack battery instead of a slide-style, there’s a little more wiggle room. Bosch brings their battery in at an angle to the front of the motor, giving it an odd look compared to the other options out there.
It’s the placement that allows you to keep your hand closer to the cutting edge and wrap your fingers around the front, giving you control as you pull the router across the grain. Rubber overmold helps maintain your grip and offers some comfort.
Considering this tool’s sole goal of edge routing, the design works well. Even though it’s far different from standard trim router designs, it not difficult to find a comfortable grip.
Accessory Changes and Depth Adjustment
You’ll need an included wrench to change router bits. To lock the collet, just pull the red bar above it out. You may have to rotate the collet a little until you find the right placement.
Depth changes are pretty simple. A button on the left side releases the base for rough depth setting and the thumbwheel just below it gives you fine adjustments. On the right side, a twist of the knob locks the base at the depth you set.
Size and Weight
Considering you can get higher performance from a cordless router, it’s the size and weight that may draw you towards this model. Dimensionally, it’s 8.5 inches tall without a battery and 5.7 inches long. The shape is much different than standard cordless models, of course.
The router weighs just 2.2 pounds bare. There are a couple of other models that get near 2.5 pounds , but most of the best are closer to 3 pounds or more.
Bosch 12V Cordless Edge Router Performance
To set a clear expectation, this isn’t a DIY router or something designed to do what your corded or 18V routers can do with a shorter runtime. This is a palm router or edge router. With 13,000 RPM to work with, it’s well under what you see from trim routers, including on the cordless side.
As long as you’re using the router for light edge routing and trimming, it’s not going to be a problem. I ran the router through some tests with a 1/4″ x 1/2″ beading bit and a 22° x 3/8″ bevel bit and am impressed with the confidence the motor delivers. The key to getting the best performance from the Bosch 12V Cordless Edge Router is to take your time, especially in hardwood, and let the motor do the work.
Additional Noteworthy Features
- Drop detection: the router automatically stops if it senses a drop
- Restart protection: the motor won’t start up if you switch batteries with the power switch on
- Finger barriers: help prevent accidental finger contact with the bit and collet
- Constant speed circuitry: the brushless motor automatically adjusts the power with the load
Bosch 12V Cordless Edge Router Price
As a bare tool, this Bosch 12V router is $149. There aren’t any kits or combos available at the time we’re writing this, so you’ll need to grab a battery and charger if you don’t have other Bosch 12V tools. There’s a chance you can get an 18V cordless router for a similar price, so shop around if you think you can use more power and versatility.
The Bottom Line
The Bosch 12V Edge Router is an excellent solution for wrapping up trimming and edging, especially for job site carpenters. When you produce most of the build at the shop and have to make some slight tweaks during installation on-site, it’s a huge help to bring out this 2.2-pound router and leave your corded trim router in the truck or back at the shop. That said, there are other cordless routers in the same price range that offer higher performance, so make sure this is what you want before pulling the trigger.
