2 forum posts | A fine cross cut blade on a sturdy drop saw will work to cut Al section. We use at work, a vegetable oil that is lightly misted onto the blade from both sides. When the blade dulls, the metal will feel warm to touch. You can use a special AL cutting blade, but a regular blade will work as long as you are careful. We clamp both sides of the piece in the dropsaw. At home I cut al extrusions on a battery powered dropsaw. I just use the fine cross cut carbide blade. It is only a 2mm kerf. I use a piece of wood against the back rail for each cut, to support the extrusion and it makes a very clean exit cut. I use a piece wood also on the front and clamp when possible clamp it on both sides. If I am only cutting a small piece off one end, with my saw, I clamp the assembly from the LH side, as the motor is on the RH side. At home I have the vaccum on the back of the saw, and have made some cardboard sides to help capture the chips etc. I use a squirt of wd40 or crc from a spray can onto the front of the blade as it is cutting. With the whole assembly clamped in place, I only need one hand to control the saw. |
