Frequently Asked Questions
What is a CLE-LINE Extra Long Drill Bit used for?
This CLE-LINE 7/16" extra long drill bit is designed for deep-hole drilling in metal, wood, and plastics where standard-length bits cannot reach. Its 18" overall length and 118° notched point provide efficient chip evacuation and reduced walking on curved surfaces, making it ideal for maintenance, fabrication, and production environments.
What are the specifications of the CLE-LINE C20493 drill bit?
The CLE-LINE C20493 is a 7/16" (0.4375") diameter high-speed steel extra long drill bit with an 18" overall length. It features a black oxide finish for corrosion resistance and a 118° notched point for self-centering. The bit is made from HSS for durability in ferrous and non-ferrous materials.

How to select the right extra long drill bit for deep hole drilling?
Choose a bit with sufficient overall length to reach the hole depth, typically 3-4x the hole depth. For steel, use HSS with a 118° point; for harder alloys, consider cobalt or carbide. The CLE-LINE C20493's black oxide finish reduces friction, and its notched point helps prevent walking on entry.
