High-Speed Steel Extended-Length Drill Bits

High-speed steel extended-length drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide extended-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 extended-length drill bits have longer flutes and more overall length than standard jobber-length drill bits of the same size, and they have longer shanks than taper-length drill bits. Their extra length allows them to create deep holes or drill into hard-to-reach workpieces.
