When cutting EVA foam, both spiral and straight flute tools can be used depending on the specific requirements of the job. Here are some differences between the two types of tools:
- Chip evacuation: Spiral flute tools have a?helical flute?that helps to evacuate chips and debris from the cutting area more efficiently than straight flute tools. This can be particularly useful when cutting?EVA foam, which can produce a large amount of dust and debris.
- Surface finish: Straight flute tools tend to produce a smoother surface finish than spiral flute tools. This is because the?straight flutes?create less friction and generate less heat, which can lead to a cleaner cut.
- Cutting speed:?Spiral flute tools?are designed to operate at higher cutting speeds than straight flute tools. This is because the helical flute helps to reduce the amount of heat generated during cutting, allowing for faster cutting speeds without damaging the tool or the workpiece.
- Cutting depth: Straight flute tools are generally better suited for shallow cuts, while spiral flute tools are better suited for deeper cuts. This is because the helical flute of spiral flute tools helps to evacuate chips more efficiently, reducing the risk of clogging or jamming.
In summary, when cutting EVA foam, straight flute tools may be preferred when a smooth surface finish is required and when cutting depths are relatively shallow. Spiral flute tools may be preferred when higher cutting speeds and deeper cuts are required, and when efficient?chip evacuation?is important.
