Chip-Clearing Drill Bits
Black-Oxide Parabolic Spiral Flute
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.

Extended-Length Chip-Clearing Drill Bits
Access hard-to-reach spots and drill deep holes. Parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. The split point keeps the bit centered without a pilot hole.

Chip-Clearing Drill Bit Sets
The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. These bits are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit centered without a pilot hole.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than black-oxide drill bits.
