Frequently Asked Questions

What is the CLE-LINE Jobber Length Drill Bit 8.1 mm used for?

This CLE-LINE cobalt jobber-length drill bit is designed for general-purpose drilling in hard materials such as stainless steel and alloy steels. The 135° split point reduces walking and allows precise entry without a center punch, making it suitable for maintenance, fabrication, and production environments.

What are the specifications of the CLE-LINE C18971 drill bit?

The CLE-LINE C18971 is an 8.1 mm jobber-length drill bit with a 135° split point and a straw/bronze cobalt finish. It has a manufacturer part number C18971 and a decimal equivalent of 0.3189 inches. The cobalt construction provides heat resistance and extended tool life in demanding applications.

Where to buy CLE-LINE drill bits worldwide?

3G Electric supplies CLE-LINE drill bits worldwide. As a global industrial equipment distributor established in 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on the C18971 or other CLE-LINE tooling.

How to select the right CLE-LINE cobalt drill bit for stainless steel?

For stainless steel, choose a cobalt jobber-length bit like the CLE-LINE C18971 with a 135° split point. Cobalt alloy maintains hardness at high temperatures, reducing work hardening. Use proper cutting fluid and moderate speeds to extend bit life. Match the bit diameter to your hole size requirement.
