Chicago-Latrobe 11009 High Speed Steel Aircraft Extension Drill Bit, 3/16 In Cut Diameter, 135°, 6 In

The Chicago-Latrobe 11009 High Speed Steel Aircraft Extension Drill Bit is engineered for applications requiring extended reach into deep or obstructed areas. Its high-speed steel construction and steam oxide finish provide the durability and heat resistance necessary for consistent performance in demanding industrial environments.

• Extended 6-inch overall length allows for precise drilling in hard-to-access locations without sacrificing tool stability.
• The 135-degree split point tip is self-centering, which eliminates bit walking and reduces the thrust required for faster starts.
• Steam oxide surface treatment improves chip flow and reduces chip welding, extending the life of the tool during repetitive use.

This aircraft extension drill is ideal for professionals in the aerospace, automotive, and maintenance industries who need reliable, long-reach tools for drilling in mild steel and general-purpose metalworking applications.
