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 reduce walking and cutting force, making it ideal for precision hole-making in sheet metal and structural assemblies.

What are the specifications of the CLE-LINE C23800 drill bit?

The CLE-LINE C23800 is a #40 high-speed steel aircraft extension drill with a 12" overall length, 135° split point, and black oxide finish. The wire-gauge diameter is 0.0980 inches. It is designed for extended reach in confined spaces and resists wear on ferrous materials.

Where to buy CLE-LINE C23800 aircraft extension drill worldwide?

3G Electric supplies and delivers the CLE-LINE C23800 aircraft extension drill worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure the drill reaches your facility, whether for aerospace maintenance or general fabrication.

How to select the right aircraft extension drill for tight spaces?

Select an aircraft extension drill like the CLE-LINE C23800 based on reach length, shank diameter, and point geometry. For confined areas, a 12" overall length with a 135° split point reduces bit walking. Match the wire-gauge size (#40, 0.0980") to your fastener or hole requirement for clean results.
