An aircraft extension bit gets a hole where a standard jobber-length bit cannot reach - through wall cavities, into framing bays, and around obstructions. The 135-degree split point starts cutting on contact instead of skating across the surface, and the black oxide finish resists corrosion.

• 135-degree split-point tip starts drilling immediately and eliminates walking
• Premium high speed steel with a black oxide coating for corrosion resistance
• Straight shank
• Drills metal, plastic, and wood
• Bit diameter: 1/8"
• Flute length: 1-5/8" - this is the deepest the bit will cut
• Overall length: 6"
• Ideal where extended reach is needed, such as running wire and cable. Not recommended for deep drilling applications.
