Review on 🔵 BOSCH RM618 6-Inch 18T Metal Cutting Reciprocating Saw Blades - 5 Pack: High-Performance Efficiency in Blue by Brian Cooper

Purchased to fell a metal basketball post embedded in concrete. Cut off the top half very quickly and I was really impressed. I went to cut just below ground level and after a few seconds the blades started to smoke very heavily. I tried again on a different part of the bar with the same results. I changed the blades and the same. Then I realized that when sinking the bar I had also filled the hole with concrete about 18 inches - the blades went through the metal and hit the hard concrete - not good for a blade! So then I just walked through the metal and hit it with a sledgehammer to knock it off. For metal these blades are great!
