5. Operation
Once the Dremel 670 Mini Saw Attachment is securely installed, you can begin cutting. This attachment is designed for precise, straight, and perpendicular cuts in materials such as plastic and wood.
- Prepare Workpiece: Securely clamp the material you intend to cut. This prevents movement and ensures a straight cut.
- Set Up Tool: Ensure the rotary tool is set to an appropriate speed for the material being cut. Refer to your Dremel rotary tool's manual for recommended speed settings.
- Align Cut: Position the attachment so the directional guide aligns with your desired cut line. The clear housing provides better visibility of your project and the cutting path.
- Begin Cutting: Turn on the Dremel rotary tool. Gently lower the spinning blade into the material. The lower guard will retract as the blade engages the workpiece. Apply steady, even pressure, allowing the tool to do the work. Do not force the cut.
- Maintain Straightness: Utilize the angled throat design to maintain straight, perpendicular cuts.
- Maximum Cut Depth: The attachment is designed for cuts up to 1/4 inch (6.35 mm) thick. Do not attempt to cut materials exceeding this thickness.
