Chip-Clearing Cobalt Steel Drill Bits
Uncoated
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.
