431V91 Solid Carbide Screw-Machine Length Drill Bits

$92.10

Bulk orders will be discounted, please contact us.

Helical-flute drill bits create smaller chips and evacuate them more quickly than standard spiral-flute drill bits. These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Coolant-through drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
