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. The 12" overall length and 135° split point reduce walking and improve accuracy on curved surfaces.

What are the specifications of the CLE-LINE C23791 drill bit?

The CLE-LINE C23791 is a #31 high-speed steel aircraft-extension drill bit with a 0.1200" diameter, 12" overall length, and a 135° split point. It features a black oxide finish for increased lubricity and heat resistance.

Where to buy CLE-LINE C23791 worldwide?

3G Electric supplies the CLE-LINE C23791 aircraft extension drill bit worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other CLE-LINE tooling.

How to select the right aircraft extension drill bit?

Select an aircraft extension drill bit based on hole size, material, and reach required. For hard metals and angled starts, a 135° split point like the CLE-LINE C23791 reduces walking. Black oxide HSS provides better chip flow and wear resistance in production drilling.
