Question: 1 / 445

How many teeth should ideally be in contact with the material during cutting?

1 tooth

2 to 3 teeth

When cutting materials, having 2 to 3 teeth in contact with the material is optimal because this configuration allows for an effective cutting action while providing better control over the cutting process. With 2 to 3 teeth engaged, there is a balance between efficient material removal and reduced load on each individual tooth, which helps to prevent overheating and wear.

Having too few teeth, like just 1 tooth, can lead to excessive stress and potential breakage. If more than 3 teeth are engaged, while it may seem beneficial for stability, it can actually reduce the efficiency of the cutting process since the material may be removed too slowly, causing the teeth to drag and generating more heat. Thus, 2 to 3 teeth in contact is the sweet spot for most cutting operations, allowing for swift and effective machining while maintaining the integrity of the tool.
