High-Speed Steel Extended-Length Drill Bits
Available574 products
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.

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.

Metric Bright Finish Parabolic-Flute High-Speed Steel Extended-Length Drill Bits
These drill bits come in standard sizes expressed in millimeters. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the 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.

Fractional-Inch Bright Finish Parabolic-Flute High-Speed Steel Extended-Length Drill Bits
These drill bits come in standard sizes expressed in fractional inches. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the 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.

Decimal-Inch Bright Finish Spiral-Flute High-Speed Steel Extended-Length Drill Bits
These drill bits come in standard sizes expressed in decimal inches. 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.

TiNAl-Coated Parabolic-Flute High-Speed Steel Extended-Length Drill Bits
The TiNAl coating on these drill bits provides a low-friction surface and is suitable for drilling most materials. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the workpiece. These bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.

Wire-Size Bright Finish Parabolic-Flute High-Speed Steel Extended-Length Drill Bits
Wire-size drill bits come in standard sizes that correspond to American Wire Gauge (AWG) sizes. The larger the wire size, the smaller the bit. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drill moves deeper into the workpiece. The bright finish on these drill bits is not affected when their cutting edges are resharpened.
