Titel: POINT ANGLE

Frage: What do different point angles on drills indicate?

Antwort: The flatter the angle, the thicker the chip; the sharper the angle, the longer and thinner the chip. Basically, a small point angle is used for a soft material. With increasing hardness of the material, a larger first-cut pressure is required, which a smaller point angle can no longer withstand since this influences the relationship of the chip cross-section.
