Review on 🔲 Stainless Triangle External Chamfer Deburring Tool by Jerry Mangum

I made the mistake of using it on my impact wrench because of the quick release hex head. The hex head would not engage my drill bit. I tried to deburr the broken bolt and click! The whole piece exploded. It looked like the inner metal was coated with a cheap silver film. Then I used a triangular base bit and it worked better. With a little work I was able to tighten the nut.
