Measure and imprint the ideal length on the 4×4 where you want to cut. Use a square or carpenter’s square to ensure your cut is perpendicular to the length of the board.
2. Set the Miter Angle
If you need to make a mitered or angled cut, adjust the miter angle on your 12-inch miter saw to the desired angle. For a straight crosscut, set the miter angle to 0 degrees.
3. Set the Bevel Angle
Some 12-inch miter saws allow you to tilt the blade for beveled cuts. If you’re making a beveled cut, set the bevel angle to 0 degrees for a straight cut or the desired degree for a beveled cut.
4. Secure the 4×4
Place the 4×4 lumber on the miter saw’s base against the fence, with the marked cut line aligned with the saw blade. Ensure the 4×4 is firmly pressed against the fence and the saw’s base to prevent movement during the cut.
5. Start the Saw
Please turn on the 12-inch miter saw and wait for it to reach full speed before cutting.
6. Make the Cut
Lower the saw blade slowly and steadily to cut. Keep both hands on the saw’s handles and maintain a firm grip. Allow the blade to complete the cut at a consistent pace. Do not force the saw through the material; let the blade do the work.
7. Release the Trigger
Once the cut is complete, release the saw’s trigger and permit the sharp edge to reach a standstill previously raising it.
8. Check the Cut
After the cut, inspect it to ensure it is straight, clean, and matches your marked line. Use sandpaper or a record to streamline any harsh edges if necessary.
9. Turn Off the Saw
Please turn off the 12-inch miter saw and trust that the cutting edge will stop before lifting it.
Can a 12-inch Miter Saw Cut a 4×4 in a Single Pass?
Yes, a 12-inch miter saw can typically cut through a standard 4×4 piece of lumber in a single pass. A standard 4×4 measures approximately 3.5 inches by 3.5 inches in cross-section, and a 12-inch miter saw typically has a maximum cutting capacity of around 7.5 inches wide and 3.5 inches thick at 90 degrees.
Therefore, a 12-inch miter saw’s blade can extend through the entire width and thickness of a 4×4 piece of lumber in one pass, allowing you to make clean and accurate crosscuts without needing multiple cuts or flipping the material.
This cutting capacity makes 12-inch miter saws well-suited for tasks that involve cutting larger and thicker materials, such as framing, deck building, and woodworking projects that use substantial stock.
