Bosch recently introduced routers that they claim have the highest power-to-weight ratio in the industry. We believe them. The 1617EVSB is one member of Bosch's new Magnesium line. This variable-speed router features a stout, 2-1/4-horsepower motor coupled with an all-magnesium base and housing. The result is a well-balanced and smooth-operating machine that offers fast results in demanding applications. We love the nicely finished hard-maple handles that make this router feel like a fine-woodworking tool. Something Bosch engineers are proudest of is what they call the "precision centering system," which makes the router bit track at true center. It's an important feature for multiple-pass applications, like jig cutting, and fine woodworkers will particularly appreciate it. Ease of height adjustment is a way of measuring quality in routers, and Bosch has come up with a system that works as well as any we've tested. A large flip lever releases the motor for adjusting. Rather than twisting as the height changes, the motor raises and drops in a straight path. The result is a simple and smooth-working course adjust that couples with an efficient microadjust to make fine-tuning the depth of cut easy and accurate. Another feature we like is the reversible motor, which lets the user place the switch and cord on either side. It's good for lefties, and for those of us who get annoyed when the cord always seems to be in the way. The collet is self-releasing, which means there's no need to tap the spindle to change bits, and the collet depth is 13/16 inch, a few 16ths deeper than that of DeWalt or Porter-Cable--one more weapon in the Bosch battle to for a truly centered bit. --Mark McDonald
