Eastwood Skip-Proof Spotweld Cutter
Product Review (submitted on March 21, 2013):
The cutter does well at first. When doing a project as involved as the cowl vents on early Mustangs, the cutter does not last very long. Even with the use of oil and the constant removal of debris, I think they get dull way too fast. It is good that there are replacement cutters and pilot bits, but they too are a bit pricey, especially when you add the shipping. Botom line though, I don't know of another product that would do a better job.
