Let's Get Started
To reduce the risk of injury user must read instruction manuals for all tools used in this project. Wear eye and respiratory protection. Use clamps to support work piece whenever practical.
After you have selected the area you'd like to place your recessed lighting (over a sink, table or island are popular choices), check to make sure your light will clear ceiling joists and that you won't encounter any other surprises while making your cut. Mark a circle on the ceiling where you'd like to locate your cut. We traced the outline of our fixture to mark our cut. TIP: Read all safety and installation instructions on your lighting. Additionally, make sure to follow all electrical safety rules like making sure the power is off and adhere to your local code specifications when handling wiring.
Mount the MM435 accessory onto your tool. You will note that the tool is set at a slight offset. This is to ensure that you are getting the optimum angle for the best cut. Set your tool to high speed and plunge right in along your mark. Notice how easily the tool plunges! Work slowly around the circle. You may need to re-position your hands while you are coming around the final portion of your cut. The drywall plug may not fall completely out once you have completed your cut, so you may need to pull it out.
Place your fixture into the newly cut hole. You may want to caulk around the fixture for the surest fit.
Finish your newly cut hole with your recessed trim. Refer to this link from Dremel DIY Guides on how to pull cable through your ceiling to bring electricity to your new lighting.
