Question: 1 / 400

What are drill bits with long deep spiral flutes specifically designed for?

Easy chip removal

Drill bits with long deep spiral flutes are specifically designed for easy chip removal. The deep spiral flutes create ample space for the chips produced during drilling to be expelled from the hole. This design is particularly beneficial when drilling deep holes because it helps to prevent clogging and ensures a smooth drilling operation.

The long flutes allow for chips to be carried upward and away from the cutting edge, reducing the possibility of re-cutting the chips and improving the efficiency of the drilling process. Additionally, effective chip removal reduces heat buildup, which can prolong the life of the bit and improve the quality of the drilled hole. This characteristic is essential in various applications, especially when working with materials that produce a lot of debris.
