Abstract:
The present invention provides a novel drill insert having chipbreakers, or chip splitting grooves formed through the cutting surfaces. The cutting tool insert has a specialized geometry including a chip splitting groove formed at a negative rake angle. The chip splitting grooves increase the cutting efficiency of the tool while allowing the edge strength to be increased while also allowing higher feed rates.
