Chip-Clearing Drill Bits

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.
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.

Cobalt Steel Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Chip-Clearing Cobalt Steel Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All 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.
