Order LookupTaper-Length Drill Bits
Available4 products
Taper length drill bits have a longer flute length and can drill deeper holes than jobber-length drill bits of the same size. Sometimes called long-series drill bits or long jobber drills, they are shorter than extended-length bits. The bits' shank diameter and flute diameter are the same.

Coolant-Through EgiAs-Coated Spiral-Flute Solid Carbide Taper Length Drill Bits
The EgiAs coating on these drill bits resists oxidation at high temperatures and provides excellent hardness and heat resistance. The coating protects the bits from wear in high-speed drilling applications with steel, cast iron, and hardened steel with a Rockwell hardness of 35 to 50 HRC. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
