High-Speed Steel Left-Hand Drill Bits
Black and Gold Oxide
Uncoated
Black Oxide
Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are jobbers' length and have the rigidity and length required for most applications.
Black-oxide and black-and-gold-oxide drill bits produce less friction than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Cobalt Steel Left-Hand Drill Bits
Uncoated
Titaniam Nitride (TiN) Coated
Titanium Aluminum Nitride (TiAIN) Coated
With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life. Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are maintenance length, also known as mechanics’ length. They are shorter and more rigid than jobbers’ bits but longer than short-length bits. The 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 uncoated drill bits.
Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.
