Frequently Asked Questions
- Q: What materials can the Drill America Cobalt Aircraft Extension Drill Bit effectively drill? A: The Drill America Cobalt Aircraft Extension Drill Bit is effective in drilling tough, high tensile strength materials such as stainless steel, inconel, and titanium.
- Q: What is the purpose of the 135° split point on this drill bit? A: The 135° split point is designed to be self-centering and helps reduce thrust, preventing the drill from walking during use.
- Q: What is the overall length of the Drill America Cobalt Aircraft Extension Drill Bit? A: This drill bit has an overall length of 6 inches, making it suitable for applications where extra reach is required.
- Q: Are these drill bits suitable for high-speed steel applications? A: Yes, these cobalt drill bits are similar to high-speed steel but offer improved performance when cutting harder metals.
- Q: What type of shank does the Drill America Cobalt Aircraft Extension Drill Bit have? A: The drill bit features round shanks, allowing for compatibility with a wide variety of tool holding systems.
- Q: How does the gold oxide surface treatment affect the drill bit? A: The gold oxide is a thinner oxide surface treatment that provides performance similar to uncoated tools while helping to identify cobalt steel tools.
- Q: What standards are the Drill America Aircraft Extension Drills manufactured to? A: These drill bits are manufactured to National Aerospace Standard 907, ensuring they meet high-quality specifications.
- Q: What sizes are available for the Drill America Aircraft Extension Drill Bits? A: The Drill America Aircraft Extension Drills are available in various sizes, including options for 6 inches and 12 inches overall lengths.
- Q: Can I use these drill bits for drilling materials other than metals? A: While they are primarily designed for tougher metals, they may also be used for drilling other materials, but performance may vary.
- Q: Is a specific drill bit point angle required for materials smaller than 1/16 inches? A: Yes, sizes smaller than 1/16 inches feature a 118° standard point instead of the 135° split point.
