Order LookupCoolant-Through Solid Carbide Jobber-Length Drill Bits
Available29 products
These solid carbide jobber-length drill bits have holes that carry coolant from the drilling machine down to their tip. The coolant lubricates and cools down the drill bit to improve drilling precision and prevent wear to its cutting edges. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel, cobalt, or powdered-metal drill bits and require a rigid setup such as a fixed-spindle machine. The bits create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Jobber-length drill bits provide a good balance of strength and accuracy when drilling into a variety of materials.
Overall Length
WXL-Coated Spiral-Flute Coolant-Through Solid Carbide Jobber-Length Drill Bits with Straight Shank
The WXL coating on these drill bits protects them from wear and is designed for drilling nonferrous metals and steels with a Rockwell hardness of up to 50 HRC. It is harder and has a higher oxidation temperature than a TiAlN coating. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder.

EgiAs-Coated Spiral-Flute Coolant-Through Solid Carbide Jobber-Length Drill Bits with Straight Shank
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. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder.

Metric TiNAl-Coated Spiral-Flute Coolant-Through Solid Carbide Jobber-Length Drill Bits with Straight Shank
These drill bits come in sizes expressed in millimeters. They have a TiNAl coating that provides a low-friction surface on the tool and is suitable for drilling most materials. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder.
