Using a saw or a miter saw: These power tools can be used to cut flexible ducting, but they require more skill and experience.
Precautions When Cutting Flexible Ducting
When cutting flexible ducting, it’s essential to take some precautions to avoid damaging the ducting or causing injuries:
-
Wear protective gear, including gloves and safety glasses
-
Use a stable and secure work surface
-
Avoid cutting the ducting at an angle, as this can cause the material to fray or tear
-
Use a straight edge or guide to ensure a straight cut
-
Avoid applying too much pressure, which can cause the ducting to deform or kink
Tips for Cutting Flexible Ducting
Here are some additional tips to keep in mind when cutting flexible ducting:
-
Use a clean and dry work surface to prevent the ducting from slipping or sliding
-
Use a ruler or measuring tape to ensure accurate measurements
-
Apply a small amount of lubricant, such as silicone spray, to the cutting tool to reduce friction
-
Use a deburring tool to remove any rough edges or burrs

Frequently Asked Questions: Can You Cut Flexible Ducting
What is the best way to cut flexible ducting?
When cutting flexible ducting, it’s essential to use a sharp utility knife or a specialized duct cutter to ensure a clean and precise cut. Avoid using scissors or dull blades, as they can crush or tear the ducting material, leading to reduced airflow and efficiency.
Can I cut flexible ducting with a saw?
While it’s technically possible to cut flexible ducting with a saw, it’s not the recommended method. Saws can generate heat, which can damage the ducting material, and may also create rough edges that can cause air leaks. If you must use a saw, use a fine-toothed blade and keep it cool to prevent damage.
How do I measure and mark flexible ducting for cutting?
To ensure accurate measurements, use a flexible measuring tape or a string to measure the length of ducting needed. Mark the ducting with a permanent marker or a piece of tape, making sure to account for any fittings or connections. Double-check your measurements before cutting to avoid errors.
Can I cut flexible ducting at an angle?
Yes, you can cut flexible ducting at an angle, but it requires some care. Use a miter box or a specialized ducting cutter with an angled guide to ensure a precise cut. Cutting at an angle can be helpful when installing ducting in tight spaces or around corners.
What should I do after cutting flexible ducting?
After cutting flexible ducting, use a duct sealant or tape to seal the cut end to prevent air leaks. Make sure the sealant or tape is compatible with the ducting material and follows the manufacturer’s instructions. Additionally, inspect the cut end for any debris or rough edges and clean or trim them as needed to ensure a secure connection.
