Micro Plunge Base: for High Speed Rotary Tools

“The term ‘precision’ tends to be thrown around with abandon, but in this case, it’s warranted. Imagine gene-splicing a micrometer with a plunge base and then shrinking it; that’s the new Micro Plunge Base from Micro Fence” — Brad Holden, American Woodworker Magazine

The Micro Plunge Base was designed with fine detailing in mind. It’s a smaller (4″ diameter base), lighter plunge mechanism with the patented micrometer dial to provide measurement for depth-of-cut. It features silky smooth plunge action, extreme stability, and precision with maximum visibility. This is an all US-made machine tool made of solid aluminum and hard chrome-plated stainless steel with stainless springs, bronze sleeve bushings, and acrylic tool inserts. It is fabricated to precise standards and is all corrosion/rust resistant.

The Micro Plunge is ideal for light-duty jobs such as installing small hardware (like jewelry boxes), architectural detailing, inlay work, picture frame-building, luthier work, scale model building, and precision repair requirements.

The Micro Plunge comes with some basic accessories that add to its versatility. There are also optional additions that can further the tool’s applications. Included is one Acrylic Insert for the motor of your choice (see the drop-down box below to select your model), a pair of Auto-Centering Bearings, a Ball-Tipped Driver for assembly and adjustment, a sample bottle of the spindle oil we use, and all appropriate hardware to set-up and run. Other accessories are listed below and shown in the thumbnail pictures to the left (more information on each accessory is available on the Accessories page).

Note: Edge Guide or Circle Jig owners who purchase the Micro Plunge will also need the Mounting Bar to fit it properly. You can select it below, along with other important accessories.
