The high-speed steel jobber-length drill bits in these sets provide more flexibility and absorb more shock and vibration than cobalt and carbide jobber-length drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These sets contain multiple drill bits of various sizes.

The cobalt jobber-length drill bits in these sets tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel jobber-length drill bits. They provide some shock absorption and can be used in handheld power tools. These sets include multiple drill bits in a variety of sizes.

These sets contain carbide jobber-length drill bits, which provide excellent hardness, wear resistance, and heat resistance. Carbide drill bits are harder than high-speed steel or cobalt jobber-length drill bits. They 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 holes after drilling. These sets include multiple drill bits in a range of sizes.
