Frequently Asked Questions
What is a CLE-LINE aircraft extension drill used for?
A CLE-LINE aircraft extension drill is used for drilling deep holes in tight spaces, common in aerospace and metal fabrication. Its 12" overall length and 135° split point allow precise entry without walking, while the black oxide HSS construction reduces friction and extends tool life.
What are the specifications of the CLE-LINE C23742 drill bit?
The CLE-LINE C23742 is a 25/64" (0.3906") high-speed steel aircraft extension drill bit with a 12" overall length, 135° split point, and black oxide finish. It is designed for deep-hole drilling in metal and is manufactured under part number C23742.
