Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits
Available6 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.

Black-&-Gold Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Flatted Shank
The black-and-gold finish on these drill bits lubricates the bits and provides some resistance to wear and rust. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece. They also have flats on their shank that help prevent the bits from slipping in a drill chuck when drilling at high speeds or under heavy loads.

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.
Metric Bright 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 bright finish that is not affected when the bits' cutting edges are resharpened, and they have spiral flutes that evacuate chips as the bits drill into a workpiece. These bits have a straight shank that installs into a drill chuck or similar toolholder.
TiN-Coated Fast-Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
The TiN coating on these drill bits protects them from wear and heat when drilling steel, stainless steel, and aluminum. The bits have fast-spiral flutes that evacuate chips more quickly than standard spiral-flute drill bits, and they have a straight shank that installs into a drill chuck or similar toolholder.
V-Coated Fast-Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Straight Shank
The V coating on these drill bits is a multilayer TiCN coating that protects them from wear and is harder and more wear-resistant than a TiN coating. The bits have fast-spiral flutes that evacuate chips more quickly than standard spiral-flute drill bits, and they have a straight shank that installs into a drill chuck or similar toolholder.
