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-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.
Drill bits with a split point keep centered without a pilot hole.

Replaceable Carbide-Insert Drill Bits
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
