Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits
Available259 products
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.

Fractional-Inch Black-Oxide Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
These drill bits come in standard sizes expressed in fractional inches. They have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. The bits' spiral flutes evacuate chips as the bits drill into a workpiece. These bits have a straight shank that installs into a drill chuck or similar toolholder.

Wire-Size Black-Oxide Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
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. These drill bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. The bits' spiral flutes evacuate chips as the bits drill into a workpiece, and their straight shank installs into a drill chuck or similar toolholder.
Metric Black-Oxide Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
These drill bits come in standard sizes expressed in millimeters. They have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. The bits' spiral flutes evacuate chips as the bits drill into a workpiece. These bits have a straight shank that installs into a drill chuck or similar toolholder.
Letter-Size Black-Oxide Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
These drill bits come in standard letter sizes. The trade letter size for each drill bit indicates its compatibility with other tools that have the same trade letter size. The bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder.
