LenoxTools Demolition Reciprocating Saw Blade with Power Blast Technology, Bi-Metal, 9-inch, 10 TPI, 5/PK (20372960R5)

Great saw blades. Lenox is usually my go to blades for any application.

These are called Fire and Rescue blades but they couldn't cut through an eighth inch piece of steel. I burned through three of them and ended up switching to my angle grinder, which cut through no problem. They are tough blades, but evidently won't cut through very hard metals.

Excellent

Excellent quality. Used only 1 for the whole exhaust on my F250. Would buy again.

Purchased locally. I cut (so far) 20 inches worth of 3/4 inch thick hot roll mild steel plate on one blade. I think the other reviewer may have been loosing teeth on his thinner plate. You need more teeth per inch on thinner steel so individual teeth dont grab and break off. Cuts surprisingly fast, comparable to a 7 inch abrasive cutoff wheel I would say, but almost no sparks or dust.
