CLE-LINE Aircraft Extension Drill: #3, 12" Overall Lg, 135° Split Point

A CLE-LINE aircraft extension drill is used for drilling deep holes in tight spaces, common in aerospace and metal fabrication. Its extended length reaches recessed areas where standard drills cannot. The 135° split point reduces walking on curved surfaces, making it ideal for precision work on aircraft skins and structural components.

The CLE-LINE C23763 is a #3 high-speed steel aircraft extension drill with a 12-inch overall length and a 135° split point. It has a black oxide finish for increased lubricity and wear resistance. The wire-gauge size #3 corresponds to a 0.2130-inch diameter, suitable for drilling in hard-to-reach locations.

Select a CLE-LINE aircraft extension drill based on hole diameter, depth, and material. The #3 size (0.2130 inch) suits small fasteners in aluminum or steel. For deeper holes, choose a longer overall length like the 12-inch model. The 135° split point aids self-centering on curved surfaces, reducing pilot-hole needs.
