It takes guts to completely redesign a woodworking tool, especially if you throw out most of what everyone has come to know and use. Bosch’s design team has made the router completely new.
We are fortunate to have a prototype Bosch router combo set (MR23EVS) in our shop, with a fixed-base and plunge-base system. This is a prototype, so don’t be surprised if there are some minor adjustments before the tool goes on sale. However, I don’t see what else needs to be changed.
The Bosch team has tossed out the old designs and engineered a new setup that will make everyone sit up and take notice. For starters, and possibly the most innovative design change Ive seen in routers, is a trigger-control system that puts the on/off switch in the handle of the router. You say thats not new? Youre right, except Im referring to the fixed base of the router and not just the plunge or D-handle bases as other companies have done.
Heres how Bosch gets the trigger into the fixed-base handles. The router’s main element, and where innovation is most evident, is a low voltage track connection. Here, the track is attached to the variable-speed 15-amp motor and the rail is mounted to both the fixed base and plunge bases. Align the motor to either base, then slip the two together to engage the connection. It is impossible to turn the router on without the connection.
What about dust getting into the connection? The same question was asked when we first used the tool. Bosch had run a lot of tests to find any problems and came up with no issues. I did a few non-scientific tests as I used the router in my shop and I found no problems, either.
This connection allows the trigger to be in both the handles and the fixed-base arrangement. You no longer have to twist the router motor to adjust the height. Instead, you can change the cutting height just like you would with a trim router. Three notches on the fixed base allow for quick adjustment. The knob can be turned one revolution to adjust the height by 1/41 cm. After a few adjustments, it is easy to get used to.
You can also make design changes like:
Redesigned handles for the fixed base have been made better. These handles are easy to hold and more comfortable than the ones on the plunge base. No more round wooden handles to deal with.
The cord connection to the motor is located offset and on a swivel which keeps it out of view of the cut line. It is easy to place the router upside-down on the bench because there is no cord sticking out from the motor’s top.
A few companies have lights placed somewhere on the cord to indicate there is power to the tool when the tool is plugged in. Bosch has taken that concept a bit further and located twin lights (LED) in the bottom of the motor. There they shine on the work area, too. This is innovative.
The new plunge base features a 8 cm range of plunge, ergonomic handles, and smooth operation. However, I noticed that the motor could rock slightly as you plunge if all your weight is on one handle. That could cause a minor deflection in your cut. (Ill bet the Bosch folks look into that before launching the tool.) In addition, the base plate is beefed up to enhance long-term rigidity.
For a better view of the workpiece, both bases include a clear sub-base made from polycarbonate.
This router is balanced as you work and with the trigger in the handles, you have total control at your fingertips. This router, when it becomes available, will most certainly be in our shop.
