How to select the right spot weld drill bit for sheet metal?

Select a bit diameter matching the spot weld nugget size, typically 6–10 mm for automotive work. A 135° split point like the CLE-LINE C20879 helps prevent walking on curved surfaces. Cobalt construction is ideal for high-strength steel. Always use cutting fluid and moderate speed to extend bit life.
