Cobalt Steel Drill Bits
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.
Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.
Drill bits with a split point keep centered without a pilot hole.

Carbide Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. Made of solid carbide for the highest accuracy and longest tool life, they 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. The four-facet point keeps the bit centered without a pilot hole. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
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.

Carbide-Tipped Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.
Drill bits with a split point keep centered without a pilot hole.
Drill bits with 135° point angle produce smaller chips than 118° point to prevent clogging.

Drill Bits for Carbon Fiber, Fiberglass, and Graphite
These jobbers'-length bits have the rigidity and length required for most applications. They are designed to make clean holes in abrasive material. Their point keeps the bit centered without a pilot hole.
Uncoated drill bits have three drill points that make clean holes in fiber-reinforced composites without fraying or delaminating the material.
