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 reduces walking and allows precise entry into tight weld joints, making it essential for body shops and metalworking.

What are the specifications of the CLE-LINE C20478 spot weld drill bit?

The CLE-LINE C20478 is a 6 mm cobalt spot weld drill bit with a 135° split point and straw/bronze finish. It has a shank diameter of 0.2362 inches. The cobalt construction provides heat resistance for drilling hardened weld zones.

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

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 for standard automotive welds. The 135° split point on CLE-LINE bits helps center the cut. Always match the bit material (cobalt) to the base metal hardness for longer life.
