Frequently Asked Questions

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

The CLE-LINE Jobber Length Drill Bit (MPN C18930) is a general-purpose cobalt drill bit for drilling into hard metals like stainless steel and cast iron. Its 135° split point reduces walking and requires no center punch, making it ideal for production and maintenance applications in metalworking and fabrication.

What are the specifications of the CLE-LINE 4 mm drill bit?

This CLE-LINE Jobber Length Drill Bit has a 4 mm diameter (0.1575 in), a 135° split point, and a straw/bronze cobalt finish. The cobalt alloy provides heat resistance and durability for drilling tough materials. The manufacturer part number is C18930, and it is designed for general-purpose metal drilling.

Where to buy CLE-LINE drill bits worldwide?

You can source CLE-LINE Jobber Length Drill Bits worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times on the C18930 or other CLE-LINE tooling.

How to select the right CLE-LINE drill bit for metal?

For drilling hard metals, choose a cobalt jobber bit like the CLE-LINE C18930 with a 135° split point for self-centering. Match the bit diameter to your hole size (4 mm here) and ensure your drill speed matches the material. Use cutting fluid to extend bit life and prevent overheating during operation.
