SOMTA NO.4 MTS Chipbreakers



This outstanding development increases drill cutting efficiency by means of greatly improved chip control. A chipbreaker rib is positioned along the length of the flutes, which curls and breaks long chip forming material into small manageable chips for easier evacuation. There is no clogging of chips in the flutes, as small chips flow freely along the flutes. The chipbreaker drill thus cuts more freely than standard drills.

The small chips also permit coolant to flow more freely to the drill point, giving improved heat dissipation and drilling performance. As the chipbreaker rib extends down the entire flute length, the chipbreaker form and effect is retained even after conventional sharpening. The chipbreaker rib gives added rigidity, markedly increasing the number of holes per re-grind, even where chip control is not considered important.
