Cutting trim with a multitool, also known as an oscillating tool, is an effective way to make precise cuts, especially for tasks like undercutting door casings or making flush cuts against surfaces.
An oscillating multitool uses a rapidly vibrating blade to cut material, making it ideal for detailed work where larger saws might be cumbersome or cause damage. When cutting trim like baseboard, a common method involves marking the cut line and using a guide to ensure a straight result.
Steps for Cutting Trim with a Multitool
Here's a breakdown of the process, incorporating techniques used for clean, straight cuts:
- Prepare Your Workspace: Ensure the trim piece is stable. If cutting trim in situ (e.g., undercutting a door jamb), protect the surrounding floor or wall with tape or cardboard.
- Select the Right Blade: Choose a blade appropriate for wood trim. Standard wood blades or bi-metal blades work well.
- Mark Your Cut: Carefully mark the desired cut line on the trim. For cuts that need to be a specific distance from an edge, measure and draw your line accurately.
- Set Up a Guide (Optional but Recommended): To ensure a straight cut, particularly important when making cross-cuts or undercuts, use a guide. A square or a piece of scrap wood clamped firmly along your marked line works effectively. As demonstrated in the reference, placing a square back approximately four inches from the desired cut line and guiding the blade along it can help achieve a "nice, straight cut."
- Position the Multitool: Attach the selected blade to your multitool. Hold the tool firmly, aligning the blade with your marked line or the edge of your guide.
- Begin Cutting: Turn on the multitool. Gently plunge the oscillating blade into the trim along your guide or line. Let the tool do the work; avoid forcing the blade, which can cause it to wander or bind.
- Guide the Cut: Steadily guide the blade along your marked line or against your straight-edge guide. Maintain consistent pressure and control. Following a guide like a square, as shown in the reference, helps achieve a "nice clean cut."
- Complete the Cut: Continue until the trim piece is fully severed.
- Clean Up: Remove the cut piece and clean any dust or debris from the trim and workspace. You should now have a clean cut, ready for the next step in your project, such as installing new casing.
Using a guide is particularly beneficial for achieving a professional finish when appearance is critical. It turns the oscillating motion into a controlled, straight cut, preventing the blade from following the wood grain or personal inconsistencies in your hand movement.
By following these steps, you can effectively use a multitool to cut trim for various applications, from repair work to new installations.
