When using a hacksaw, having three teeth in contact with the material is essential for achieving an effective and efficient cutting action. This configuration allows for a more controlled and stable cut, reducing the likelihood of the blade binding or breaking. With three teeth engaged, the load is distributed across them, enhancing cutting performance and providing better support to the blade.

Having three teeth in contact also aids in creating a smoother finish on the material being cut. It ensures that as one tooth completes its cut and moves forward, the other two are still engaged, maintaining a consistent depth of cut and minimizing the chances of causing chatter or vibration that can result in less precise cuts.

In contrast, if too few teeth are in contact, like one or two, it may lead to uneven wear and a rougher finish, while four teeth may create unnecessary friction and resistance, making cutting more labor-intensive without increasing the efficiency significantly. Therefore, the recommendation to maintain three teeth in contact balances cutting efficiency and blade longevity.
