I have tried tin snips skil saw and a sawzall not exactly the cleanest.
Cleanest way to cut aluminum siding with a saw.
Use a nibbler to cut in a straight line.
Mark the area to cut and slowly feed the blade into the siding.
These include miter saws chop saws table saws and handheld circular saws.
This will slow your cutting speed.
Circular saws generally are suitable for cutting aluminum between 0 5 and 6 in.
Using the board as the guide for your circular saw cut down the length of the aluminum siding.
Flip the sheet over and repeat.
Cut across the contours of the aluminum siding with a radial arm saw.
With care and patience full size sheets of aluminium can be cut using this method.
The cutting speed used for wood is generally going to be too fast to safely cut aluminum.
After a few wiggles the sheet will fracture along the cut line leaving a clean break as shown in the above photos.
Be sure to work slowly in order to maintain the proper form.
My question is which tool will allow me to make the cleanest straightest cut.
Band saws generally make sense for aluminum stock of 6 in.
Install a plywood blade backward onto a circular saw.
Remember goggles and hearing protection.
If the motor housing on your saw is open and could collect metal chips tape a piece of cloth over the openings to protect the motor windings and bearings while you cut the aluminum.
Once you get use to it you can set the cut off blade for a deeper cut and free hand it using the board as a guide.
Set your circular saw to the depth of the 1 board plus another 1 8.
Use the panel to reduce the risk of snags while cutting.
For example if you use a 10 inch 25 cm saw you can reduce the blade to 7 25 inches 18 4 cm.
While cutting at the width of the aluminum siding make use of straight tin snips.
Place the fracture line over the edge of a table and bend the overhang slightly downwards.
Reduce the diameter of the cutting blade for better results.
Making accurate cuts on aluminum rods tubes and angles is easy with a miter saw and a blade designed to cut nonferrous metal check the label.
Step 2 cut the width.
