Osg 17750008 Jobber Drill - 3/4

Description

They provide a good balance of strength and accuracy when drilling into a range of materials. 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. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece.,Coolant-through high-speed steel jobber-length drill bits have holes that carry coolant from the drilling machine down to the bits' tip. Jobber-length drill bits are the most commonly used drill-bit length. 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 coolant lubricates and cools down the drill bit to improve drilling precision and prevent wear to the bits' cutting edges.
