Product Description

The Chicago-Latrobe 559TA series short length drill bit is made from cobalt steel with a TiAlN coating and has a 135-degree split point for penetrating without a pilot hole when used on ferrous materials, high-temperature alloys, and titanium. The short length provides rigidity and strength to reduce tool deflection and breakage. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool’s toughness and hardness in high drilling temperatures. The TiAlN (titanium aluminum nitride) coating provides wear and corrosion resistance in high-speed drilling. The 135-degree split point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118-degree point. Compared to a standard drill bit, this bit has a thicker web for increased strength and rigidity. The round shank accommodates most drill chucks.

Chicago-Latrobe manufactures drill bits and accessories, reamers, countersinks, and blanks. The company, founded in 1890 and headquartered in Clemson, SC, meets International Organization for Standardization (ISO) standard 9001.
