High-Speed Rotary Tool Cups for the Plunge Base allow the Dremel and Proxxon motors to be mounted in our plunge base. You'll also need the clear  Acrylic Insert that is appropriate for your rotary tool, which is why we have packaged them together for your convenience.

The High-Speed Rotary Tool Cups are machined from solid aluminum stock and are fitted with three equally spaced, brass-tipped set screws to hold the motor in secure fashion.

Clear acrylic inserts for Dremel #395 & 400XPR or Proxxon IB/E. These thread onto the nose of the high-speed rotary tools and then insert in the High Speed Rotary Tool Cups that we make and are secured by brass-tipped set screws in three locations. This assembly allows the motors to be securely held at a position closer to the work surface where their shorter tooling can be effective. We also carry extended-reach 1/8" spiral cutters listed in our router bits pages.

You can see the High Speed Rotary Tool Cups on the video page under the Plunge Base title.
