Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits
Available44 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.
Series
Black-Oxide Finish Spiral-Flute Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits with Tang Shank
The black-oxide finish on these drill bits retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece. These drill bits have a shank with a tang that prevents the bits from slipping in a drill chuck. Tang-shank drill bits can be securely inserted and removed from a compatible chuck without using tools, reducing downtime.
