Frequently Asked Questions

What is a CLE-LINE spot weld drill bit used for?

A CLE-LINE spot weld drill bit is designed to remove spot welds in automotive and sheet metal fabrication. Its 135° split point and cobalt construction allow it to drill through hardened weld nuggets without walking, making it ideal for body shops and metalworking industries.

What are the specifications of the CLE-LINE C20878 spot weld drill bit?

The CLE-LINE C20878 is a 6 mm (0.2362 inch) cobalt spot-weld drill bit with a 135° split point and a straw/bronze finish. It features a 3-flats shank for secure chuck grip. The cobalt alloy provides heat resistance for drilling through tough weld joints.

Where to buy CLE-LINE spot weld drill bits worldwide?

CLE-LINE spot weld drill bits are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for pricing and lead time on the C20878 model.

How to select the right spot weld drill bit size?

Select a spot weld drill bit diameter that matches the weld nugget size, typically 6 mm to 8 mm for automotive work. The CLE-LINE C20878 at 6 mm suits standard spot welds. Ensure the bit has a 135° split point to prevent walking and a cobalt grade for durability on hardened steel.
