The black-and-gold finish on these drill bits lubricates the bits and provides some resistance to wear and rust. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece. They also have flats on their shank that help prevent the bits from slipping in a drill chuck when drilling at high speeds or under heavy loads.

Non-coolant-through high-speed steel jobber-length drill bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt, powdered-metal, and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. Jobber-length drill bits are the most commonly used drill-bit length. They provide a good balance of strength and accuracy when drilling into a range of materials.
