Complete your woodworking or home improvement project with ease with the Bosch Under-Table Router Base. This base is compatible with Bosch 1617 and 1618 series routers. This under-table router base has convenient wrench access above the table, allowing you to easily adjust the router's depth. Threaded holes make it easy to mount the base to a router table with the Bosch 4-hole subbase pattern, as well as router tables with the common 3-hole subbase pattern. Hardware is included to make the setup process as smooth as possible. The Bosch Under-Table Router Base has a wide, 3.75-inch opening, allowing you to use larger bits. The motor housing does not rotate during depth adjustments, and 2 additional protective devices prevent the motor from falling when the quick-clamp is released. Whether you are a professional or a DIY homeowner, this under-table router is sure to be a great addition to your toolkit.
