Review on 🔪 Recut Plastic 8 Inch SC16 - Pack of 16 by Richard Sallah

These are excellent cutting attachments. I recently used them to cut holes for door locks in a 1/8" sheet steel gate post. They are made from HSS high speed steel. It's an alloy that's harder than common tool steel. Mild steel and anything softer without dulling. The only downside is that the harder the edge the more brittle it becomes. They don't bend when you cut towards the end. If you push too hard they will snap. I have a metal shop and a repair shop , and I have a bag of my Rigid 12V tool kit in my pocket, which is also excellent by the way.
