Frequently Asked Questions

What is a CLE-LINE Jobber Length Drill Bit used for?

This 8.8 mm cobalt drill bit with a 135° split point is designed for general-purpose drilling in hard materials like stainless steel and alloy steels. The straw/bronze finish reduces friction and heat, making it suitable for production and maintenance work across machining and fabrication industries.

What are the specifications of the CLE-LINE C18978 drill bit?

The CLE-LINE C18978 is a jobber length drill bit with an 8.8 mm diameter (0.3465 inches), a 135° split point, and a straw/bronze cobalt finish. It is a general-purpose cobalt bit designed for durability and heat resistance in demanding drilling applications.

Where to buy CLE-LINE drill bits worldwide?

How to select the right jobber length drill bit for hard materials?

For hard materials like stainless steel, choose a cobalt jobber bit with a 135° split point, such as the CLE-LINE C18978. The split point reduces walking and requires less thrust, while cobalt alloy maintains hardness at high temperatures. Match the bit diameter to your hole size and use proper cutting fluid.
