How to select the right CLE-LINE aircraft extension drill bit?
Select based on hole size, material, and access constraints. The #28 (0.1405-inch) bit suits small-diameter holes in aluminum or steel. The 135° split point aids self-centering on uneven surfaces. For deeper or angled drilling, the 6-inch extension length provides reach without sacrificing rigidity. Always match speed and feed to the workpiece material.
