Product Description

The CLE-LINE Aircraft Extension Drill (#31, MPN C23691) is a high-speed steel aircraft-extension drill bit with a black oxide finish, 6" overall length, and a 135° split point. It is designed for extended-reach drilling applications where standard-length bits cannot access tight spaces.

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 extended 6" overall length and 135° split point allow precise entry without walking, while the black oxide HSS construction provides heat resistance and durability for repeated use on metals.

What are the specifications of the CLE-LINE C23691 drill bit?

The CLE-LINE C23691 is a #31 high-speed steel aircraft-extension drill bit with a 6" overall length, 135° split point, and black oxide finish. The wire-gauge diameter is 0.1200 inches. It is designed for extended reach applications and is manufactured by CLE-LINE under part number C23691.

Where to buy CLE-LINE aircraft extension drills worldwide?

CLE-LINE aircraft extension drills are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver this item worldwide, handling full logistics, customs clearance, and delivery to your facility. Contact 3G Electric for availability and lead time on the C23691 drill bit.

How to select the right CLE-LINE aircraft extension drill?

To select the right CLE-LINE aircraft extension drill, match the wire-gauge size (e.g., #31 with 0.1200" diameter) to your hole requirement. Choose the 6" overall length for extended reach in confined spaces. The 135° split point reduces walking on curved surfaces, and black oxide HSS suits ferrous metals. Always verify shank compatibility with your chuck.
