CLEVELAND Aircraft Extension Drill: #7, 12" Overall Lg, 135° Split Point, HSS

The CLEVELAND #7 Aircraft Extension Drill is used for drilling precision holes in aircraft structures and aerospace assemblies. Its 12-inch overall length and 135° split point allow access to tight spaces and reduce walking on curved surfaces. It conforms to NAS 907 Type B specifications, making it suitable for demanding aerospace maintenance and manufacturing applications.

The CLEVELAND C13223 is a #7 aircraft extension drill bit with a 0.2010-inch diameter, 12-inch overall length, and a 135° split point. It is made from high-speed steel (HSS) and conforms to NAS 907 Type B standards. The 135° split point reduces thrust and prevents walking, ideal for drilling in hard-to-reach aircraft locations.
