These bits have fast-spiral flutes that evacuate chips more quickly than standard spiral flutes as the bits drill into a workpiece. The bits also have a V coating, which is a multilayer TiCN coating that protects the bits from wear and is harder and more wear-resistant than a TiN coating. This listing is for each.
