Cobalt Aircraft Extension Drill Bit, GLBCO Series

Drill America Cobalt Aircraft Extension Drills are manufactured to National Aerospace Standard 907 and are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. The 135° split point is self-centering and reduces thrust, while sizes smaller than 1/16 in. have the 118° standard point. These drills are effective in drilling tough, high tensile strength materials like stainless steel, inconel, and titanium.

The round shanks of the Drill America Aircraft Extension Drills allow use with a wide variety of tool holding systems, and the drills are available in 6 in. and 12 in. overall lengths when extra reach is required. The gold oxide surface treatment is thinner than the typically used black oxide, and the performance is similar to uncoated tools.

The 135° split point tip of the Drill America Cobalt Aircraft Extension Drills prevents the drill from walking, ensuring precise and efficient drilling. This feature, combined with the increased cobalt content for improved performance on harder metals, makes these drills a reliable choice for a variety of aerospace and industrial applications.

Overall, the Drill America Cobalt Aircraft Extension Drills offer a range of features and benefits that make them well-suited for demanding drilling tasks. The combination of the 135° split point, the gold oxide surface treatment, and the availability in different lengths provides users with a versatile and high-performing drilling solution.
