Final answer:
The best tools for DIY home projects such as cutting moulding, sanding, and polishing include a miter saw or hand saw for cutting, and a power sander or handheld rotary tool with different attachments for sanding and polishing tasks.
Step-by-step explanation:
The best tool for DIY home projects like cutting moulding, sanding, and polishing is a versatile one that can accommodate multiple attachments for different tasks. For cutting, a miter saw or a hand saw fitted with an appropriate blade is ideal for precise cuts on moulding. For sanding and polishing works, a power sander with variable speed control is useful, especially an orbital sander for smoother finishes.
Handheld rotary tools with different attachments can also be great for detailed work, allowing you to switch between cutting, sanding, and polishing tasks with ease. It is important to select tools that are appropriate for the material you are working with and the level of precision required for the project.
