This new combo kit from Bosch is feature-rich, with items such as new and unique power switch controls, as well as tried-and-true, must-have features — such as Constant-Response™ circuitry.

Aside from the new bells and whistles on these routers, though, Bosch has wisely kept key features that have worked for them in the past — which shows a good deal of common sense: if it's not broken, don't "fix" it. In this case, the "heritage" feature is the Afterlock Micro Fine Depth Adjustment system on the plunge base. Previously found on Bosch's 1613 AEVS 2Mhp plunge router, the Afterlock Micro Fine system is designed to give you easy and precise adjustment at any plunge setting — it has a plunge depth range of up to 3".

On the fixed-base MR23EVS series, you'll find a 1%" continuous microfine adjustment range. A hex wrench is included for making those microfine adjustments through the top of a router table, if you choose to mount the router for inverted use.

The motor in these routers is 15-amp, rated for 2.3hp maximum. It powers them up to a variable speed range of 10,000 to 25,000 rpm. As expected, this means the routers have a variable speed dial. The motor also has a

gentle soft start and, another carryover from previous Bosch products, Constant-Response™ circuitry, which means that the motor monitors itself to determine how much torque is needed at any given moment.

The rpm control dial is located on the front of the router and is very easy to read. It would be great if Bosch would provide a chart relating numbers to rpm.

That way, it can keep providing constant speed under load.

The MRC23EVS routers accept 1/4" and 1/2" self-releasing collets (one of each is included in the Modular Router System combo kit, seen here). The base opens to 3³/t" on the fixed base model and 3⁵/V' on the

plunge. Sub-base openings on both models are 2".

LED lights are included in these routers so you can see down inside the bit area more easily. The lights stay on whenever the motor is plugged in, whether it's turned on or not.

So, in total, what's included in the Bosch MRC23EVSK 2.3 hp Modular Router System? The official list: MR23EVS motor, fixed and plunge bases, 1/4" and 1/2" self-releasing collets, bit wrenches, T-handle hex wrench, three M4 screws for table mounting and a carrying case for the whole kit and caboodle.

It'll be available for you to see in stores in a few months (June); right now, all you get is a sneak peek of the prototype from its visit to our shop. We will reveal this much: It was quiet, well-balanced and very smooth on the test cuts we made. .A _/
