Taper Length Drill Bit: Letter W, 118° Point, Black Oxide HSS

These general purpose high-speed steel taper-length drill bits for metal and plastic absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. Regular-spiral flutes are best suited for nonchipping hard materials such as nonferrous metals, cast iron, and structural steel. Taper-Length drill bits have longer flutes to drill deeper holes than jobber-length drill bits. High Speed Steel drill bits absorb more shock and vibration than cobalt and carbide, making them suitable for use in manual drilling machines and handheld power tools. Black Oxide coating improves lubricity to reduce friction, minimize heat buildup, and improve wear resistance, chip flow, and tool life.
