High-Speed Steel Extended-Length Drill Bits
Available1 product
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.
Shank Dia.
Metric Bright Finish Spiral-Flute High-Speed Steel Extended-Length Drill Bits
These drill bits come in standard sizes expressed in millimeters. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece. The bright finish on these drill bits is not affected when their cutting edges are resharpened. The bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.
