About Drill Bits

Short-Flute Cobalt Steel Drill Bits

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.

Short-Flute Extended-Length Cobalt Steel Drill Bits

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

Short-Flute Extended-Length Carbide-Tipped Drill Bits

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

Short-Flute Extended-Length Drill Bits

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

Cobalt Steel Hole-Starting Drill Bits

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Carbide Hole-Starting Drill Bits

Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
