Silver cobalt aircraft extension drill bit 6 inch length

Drill America

Drill America GLBCOX6F 6 inch Cobalt Aircraft Extension Drill Bit

SKU CH-ENYE-S0APZ

Cobalt aircraft extension bit drills deep holes in stainless steel, inconel and titanium with 135 split point and 30% higher speeds

  • Cobalt alloy enables up to 30% faster drilling speeds than M2 high speed steel
  • 135° split point is self-centering and reduces thrust for accurate hole starts
  • 6 inch aircraft extension length provides extra reach in deep or confined spaces
  • Manufactured to Aerospace Standard 907 for consistent quality in demanding applications
  • Effective on tough high tensile strength materials including stainless steel, inconel and titanium

Aerospace Extension Drill

The Drill America GLBCOX6F is a 6 inch cobalt aircraft extension drill bit manufactured to Aerospace Standard 907. It is designed for users who need extra reach when drilling tough, high tensile strength materials such as stainless steel, inconel and titanium. The cobalt construction provides high red hardness for demanding applications.

Compatibility Check

Verify that your drill chuck can accommodate the bit shank and that the 6 inch overall length suits the depth and access requirements of your workpiece. Ensure the material you intend to drill matches the bit's capability for high tensile alloys. The 135 degree split point is self-centering and reduces thrust during operation.

Thermal And Power Characteristics

Cobalt steel maintains hardness at elevated temperatures, permitting speeds up to 30 percent greater than conventional M2 high speed steel. This heat resistance supports sustained cutting performance in difficult metals. The split point geometry lowers the force required, reducing load on the drill motor during normal use.

Questions about this item

What comes in the package and is anything else needed to start drilling?

The box contains the single 6 inch cobalt aircraft extension drill bit; no extra accessories are required to use it with a compatible drill chuck.

How do I choose between the available point styles for this bit?

This model uses a 135 degree split point that is self‑centering and reduces thrust, making it the preferred choice for tough, high tensile strength materials such as stainless steel, inconel and titanium.

What does the 30 percent higher speed claim mean when the bit is in a real drill?

The cobalt construction delivers high red hardness, allowing drilling speeds up to 30 percent greater than conventional M2 high speed steel when cutting the same hard alloys.
