Product Description

The CLE-LINE Extra Long Drill Bit (13/32") is a high-speed steel extended-length drill bit with an 18" overall length, 118° notched point, and black oxide finish (MPN C20491). It is designed for deep-hole drilling applications requiring extended reach.

Frequently Asked Questions

What is the CLE-LINE Extra Long Drill Bit used for?

The CLE-LINE Extra Long Drill Bit is designed for drilling deep holes in metal, wood, and plastic where standard-length bits cannot reach. Its 18-inch overall length and 118° notched point enable precise entry and chip evacuation in industrial maintenance, fabrication, and construction applications.

What are the specifications of the CLE-LINE Extra Long Drill Bit?

This CLE-LINE drill bit has a 13/32-inch diameter (0.4063 inches), an 18-inch overall length, and a 118° notched point. It is made from black oxide high-speed steel (HSS) for increased wear resistance and heat dissipation. The manufacturer part number is C20491.

Where to buy the CLE-LINE Extra Long Drill Bit worldwide?

You can source the CLE-LINE Extra Long Drill Bit through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other CLE-LINE tooling.

How to select the right CLE-LINE extra long drill bit for deep hole drilling?

Select a CLE-LINE extra long drill bit based on hole depth, material hardness, and required hole diameter. For deep holes, choose a bit with a 118° notched point to reduce walking and improve chip flow. Black oxide HSS provides better lubricity and heat resistance than plain HSS in ferrous metals.
