Drill America GLBCOX615/64 15/64 x 6 Cobalt Aircraft Extension Drill Bit

Drill America Cobalt Aircraft Extension Drills are manufactured to National Aerospace Standard 907, and they 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 135° split point tip prevents the drill from walking, and the round shanks allow for use with a wide variety of tool holding systems.

Gold oxide is a thinner oxide surface treatment than black oxide, typically used to identify cobalt steel tools, but the performance of these drills is similar to uncoated tools. Drill America Aircraft Extension Drills are available in 6-inch and 12-inch overall lengths, providing extra reach when needed.
