Chip-Clearing Drill Bits
Titanium-Nitride (TiN) Coated Parabolic Spiral Flute
Uncoated Parabolic Spiral Flute
Black-Oxide Spiral Flute
Uncoated Spiral Flute
These jobbers'-length bits have the rigidity and length required for most applications. The flutes are designed to lift chips out of the hole, reducing clogging and improving coolant flow.
Parabolic spiral flute drill bits have wider flutes for more efficient chip evacuation than spiral-flute bits.
Black-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and black-oxide drill bits.
Drill bits with a split point keep centered without a pilot hole.
