Left-Hand Non-Coolant-Through High-Speed Steel Jobber-Length Drill Bits
Available17 products
These bits have a left-hand drilling direction and can be used in reverse-drilling applications to remove broken screws from a hole. Non-coolant-through 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.
