Drill Bit Sets
These jobbers'-length bits 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.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Short-Length Drill Bit Sets
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.
Black-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and black-oxide drill bits.

Cobalt Steel Drill Bit Sets
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.

Carbide Drill Bit Sets
For the highest accuracy and longest tool life, these solid-carbide bits are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.
Uncoated drill bit sets are good for general purpose drilling in most metal and plastic.

Left-Hand Drill Bit Sets
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.

Hardened Undersized High-Speed M2 Tool Steel Rod Sets
- Hardness: Rockwell C60 (Very Hard)
- Yield Strength: Not Rated
Supplied in a metal index case with fold-out panels, these rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They are hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
