6" HSS Aircraft Extension Drills

Champion CS6X 6″ Aircraft Extension Drills — Long-Reach 135° Split Point HSS Drills

The Champion CS6X 6″ Aircraft Extension Drills are high-quality extension drills designed for drilling holes in hard-to-reach places where extra reach and control are needed. Ideal for aircraft assembly, structural fabrication, and maintenance work, these drills deliver consistent penetration in aluminum and low to medium steel alloys.

Built with black oxide treated high speed steel (HSS), these extension drills resist heat build-up and extend tool life in demanding drilling applications. A 135° self-centering split point ensures accurate hole starts and prevents “walking” on the workpiece surface, while spring-tempered shanks reduce bending when drilling at non-perfect alignment angles.

Key Features

• 6″ Overall Length for extended reach in deep or obstructed drilling applications.
• 135° Self-Centering Split Point reduces walking and improves hole accuracy. 
• Black Oxide High Speed Steel resists heat and increases tool life. 
• Spring-Tempered Shank prevents permanent bending and ensures durability.
• Compatible with standard drill chucks and drill presses. 

Typical Applications

• Aircraft assembly and structural drilling. 
• Maintenance and repair where deep access is required. 
• Drilling in aluminum, mild steel and low alloys. 
• General construction and fabrication tasks.

Available Sizes

Champion CS6X 6″ aircraft extension drills are available in a wide range of fractional sizes from 1/16″ up to 1/2″, matching standard jobber drill diameter options with extended reach.

⚠ Cutting tools can shatter and generate chips. Always wear appropriate PPE including eye protection and gloves. Use proper drilling speeds and lubrication when working with metals.
