Frequently Asked Questions
What is a CLE-LINE aircraft extension drill used for?
A CLE-LINE aircraft extension drill is used for drilling in tight or hard-to-reach spaces common in aerospace and metal fabrication. Its 12" overall length and 135° split point allow precise entry without walking, while black oxide HSS construction provides heat resistance and chip flow.
What are the specifications of the CLE-LINE C23728 drill bit?
The CLE-LINE C23728 is a black oxide HSS aircraft extension drill bit with an 11/64" diameter (0.1719"), 12" overall length, and a 135° split point. It is designed for deep or angled drilling in metal and composite materials, reducing thrust and improving hole accuracy.
